SPC results, limits and rules
Below are the possible results that summarize the SPC test:
Icon | Tool application | Diagnosis | Further action |
| Can be used | The tool works correctly. | None |
| Can be used | The average is higher than the upper control limit, but it does not exceed the upper tolerance limit. | Calibrate: decrease the torque |
| Can be used | The average is lower than the lower control limit, but it does not fall under the lower tolerance limit. | Calibrate: increase the torque |
| Can be used | Excessive dispersion of the values prevents proper calibration of the tool, but the measured values are still within the tolerance limits. | Repair |
| CANNOT be used | At least one value is higher than the tolerance limit. | Remove the tool from the production line and calibrate: decrease the torque |
| CANNOT be used | At least one value is lower than the tolerance limit. | Remove the tool from the production line and calibrate: increase the torque |
| CANNOT be used | Some measured values are out of tolerance limits. Excessive dispersion of the values PREVENTS proper calibration of the tool. | Remove the tool from the production line and repair |
The SPC Rules give the results listed in the above table.
Below are the SPC test limits:
UL | Upper Limit | LWL | Lower Warning Limit |
UCL | Upper Control Limit | LCL | Lower Control Limit |
UWL | Upper Warning Limit | LL | Lower Limit |
T | Target (nominal) |
Upper Limit (UL) and Lower Limit (LL) are the SPC test limits.
The SPC test limits are calculated as follows:
Upper Control Limit (UCL) = ((UL + LL) / 2) + (A · ((UL - LL) / 6))
Lower Control Limit (LCL) = ((UL + LL) / 2) - (A · ((UL - LL) / 6))
Upper Warning Limit (UWL) = ((UL + LL) / 2) + (2/3 · (UCL - ((UL + LL) / 2)))
Lower Warning Limit (LWL) = ((UL + LL) / 2) - (2/3 · (((UL + LL) / 2) - LCL))
Range = D2 · ((UL - LL) / 6)
A and D2 are coefficients that depend on the number of the SPC tests:
Number of SPC tests | A | D2 |
|---|---|---|
1 | 0.000 | 0.000 |
2 | 2.121 | 3.686 |
3 | 1.732 | 4.358 |
4 | 1.500 | 4.698 |

Tool types
The available tool types are:
Peak wrench: hand-operated tools, defined as displaying torque wrench (type I) in the ISO 6789 standard
Click wrench: hand-operated tools, defined as breakaway torque wrench (type II) in the ISO 6789 standard
Power tool: continuously rotating tool that provides real torque to the joint, like battery tools, pneumatic tools (not impulse) and electronic controlled tools
Pulse tool: tool that provides a series of pulses to tighten the joint.
Tool check testing
In the following a description of the parameters that characterized the strategies available for the tool testing.
Click strategy
Click strategy
This strategy is applicable to a click wrench with breakaway technology with one breakaway point, defined as setting torque tools (type II and class A, C, G, B by standard ISO 6789)
A | Click point |
The click-point is detected when the torque drops and then increases again, as shown in the two following examples:
A | Click point |
If the torque drops to zero without increasing again after a peak point, the peak point is not detected as click point. For this reason, slip-wrenches cannot be tested with this method (the slip-wrenches should be tested with the Peak Wrench or Cam-over strategies):
A | Point not detected as click point |
If the test ends and the click-point is not detected, a message Not detected is shown at the bottom-left area of the display. In that case the result is the torque absolute peak.
The parameters that characterize the click point detections are:
Measure delay time: this timeout is used to filter the possible spikes or noise at low torque values. When the torque reaches the Cycle Start value, the timer starts. During this time the torque trace is not analyzed and the click point is not searched.
Torque vs time A
Cycle start
B
Ignored point
C
Measure delay time
Reset time: this timeout is used to filter the possible spikes/bounces after the click-point. When the torque goes below the cycle complete value, the timer starts. During this time the torque trace is not analyzed (any click-point possibly occurring during the reset time is not considered). This timeout can be used when the click-wrench produces such spikes-bounces after the click-point.
A
Cycle complete
B
Ignored point
C
Reset time
End cycle time: this timeout defines the end of the test. When the torque goes and remains below the Cycle Complete for the given timeout, the test ends. The test ends when torque remains under the cycle complete load for the timeout (torque during the reset time is ignored).
Torque vs time A
Cycle complete
B
Reset time
C
End cycle time
Slip Torque: The slip torque gives the requested drop in torque after the click-point. If the torque drops more than the slip torque, the peak value is considered as click-point; if not, the peak value is ignored.
A
Slip torque
B
Torque drops less than the slip torque → the peak is ignored
C
Torque drops more than the slip torque → the peak is a click-point result
However, it is possible to give the slip torque manually. This option is useful in case the click-point is not detected when the slip torque is set to Automatic. In this case do the following procedure: do some tests and make an analysis by looking at the traces. Then, select the proper value in order to detect the click-point.
Suggestions: Setting this value too low increases the risk of detecting a false click-point, while setting this value too high increases the risk of not detecting the real click-point. The best trade-off can be figured out only looking at the characteristics of the specific click-wrench under test.
Cam-over strategy
This strategy is applicable to a wrench or screwdriver with clutch technology that "slips-free" when the set torque is reached, preventing under and over tightening.
The click wrenches with clutch technology are defined as setting torque tools (Type II by standard ISO 6789).
The slip-wrench test provides the maximum torque measured during the test.
The parameter that characterize the peak point detections is:
End cycle time: it defines the end of the test. When the torque goes and remains below the transducer minimum load (which is normally the 5% of the transducer full scale) for the given timeout, the test ends.
If the torque goes over transducer minimum load before the timeout, the test continues. The test ends when torque remains under the transducer minimum load for the timeout.
Torque vs time A

B
Transducer full scale
C
Timeout
Peak strategy
This strategy is applicable to a peak wrench, defined as indicating torque tools (type I by standard ISO 6789).
The peak wrench test provides the maximum torque measured during the test.
The parameters that characterize the peak point detections are:
End cycle time: it defines the end of the test. When the torque goes and remains below the transducer minimum load (usually 5% of the transducer full scale) for the given timeout, the test ends.
If torque goes over transducer minimum load before the timeout, the test continues. The test ends when torque remains under the transducer minimum load for the timeout.Torque vs time A
Transducer min load
B
Transducer full scale
C
End cycle time
Relaxation time + End cycle time: due to the mechanical relaxation of the wrench, the torque peak detected by the wrench slightly decreases after a short time interval. The relaxation time allows to adjust the peak detection in case of wrenches that do not save the torque peak, thus reducing discrepancies between the transducer and the wrench torque peak detections. If Relaxation time > 0, the End cycle time starts when the Relaxation time expires.
Torque vs time A
Torque peak
B
Relaxation time
C
End cycle time
Direct driven strategy
For power tool test, the torque result is the peak value measured during the test.
In case of multiple peaks, the result is the highest peak.
Testing the tool with a torque/angle transducer makes possible to define a torque/angle window in which the result is OK.
The parameter that characterize the peak point detections are:
Measure delay time: this timeout is used to filter the possible spikes or noise at the beginning of the test. When the torque reaches the Cycle Start value, the timer starts. During this time the torque trace is not considered.
Torque vs time A
Cycle start
B
Ignored point
C
Measure delay time
Reset time: this timeout is used to filter the possible spikes/bounces after the tool clutch release the torque. When the torque goes below the cycle complete value, the timer starts. During this time the torque trace is not considered.
Torque vs time A
Cycle start
B
Ignored point
C
Reset time
This timeout can be used in those cases where the power tool produces such spikes-bounces at the end of the test.
End cycle time: this timeout defines the end of the test. When the torque goes and remains below the Cycle Complete for the given timeout, the test ends.
Torque vs time A
Cycle complete
B
Reset time
C
End cycle time
The Cycle Complete must be equal or less than the Cycle Start. The value of the End cycle time must be equal or greater than the Reset time value.
Measure angle from
Below an example of a complete curve in which the measurement of the angle starts as soon as the torque reading starts, to be compared with the curves representing the angle measured from One step/Second step/Starting second step:
A | Torque [Nm] | B | Angle [°] |
C | Time [ms] |
One step: the measurement of the angle starts as soon as the Final monitoring torque value is reached.
A | Torque [Nm] | B | Angle [°] |
C | Time [ms] |
Second step: the measurement of the angle starts in the second step, when the Final angle monitoring torque value is reached.
A | Torque [Nm] | B | Angle [°] |
C | Time [ms] |
Starting second step: the measurement of the angle starts at the starting of the second step.
A | Torque [Nm] | B | Angle [°] |
C | Time [ms] |
Only angle strategy
This strategy is available for the power tools.
It is possible to make a specific test to verify the angle of a tool.
Suggestion: In this case the Final angle monitoring torque defines the torque value from which the angle is measured. Leave it to zero to measure the angle without applying any torque.
Pulse strategy
To calculate the tool frequency, the Pulse Tool strategy uses a configurable threshold to identify a peak.
The parameter that characterize the peak point detections are:
End cycle time: when the torque goes and remains below the transducer minimum load (which is normally the 5% of the transducer full scale) for the given time, the test ends.
Timeout can be set from 0.1 s up to 5 s. The default value is 0.4 s.
Torque vs time A
Transducer min load
B
Transducer full scale
C
End cycle time
Torque coefficient: Pulse tools do not provide a continuous torque output, but they generate single high energy pulses of very short duration (» 1ms). This series of pulses results in the tightening of a joint. Due to the physics of the tool the final torque reached cannot be measured directly as for real torque tools. The reason for this is that pulse tools provide a very high torque for such a short time that only a part of these peaks translates into the tightening of the joint (generating more clamping force). This depends on many factors such as the bolt mass, friction, the stiffness of the joint, etc... The torque coefficient can be used to align the torque measured by the transducer with the real torque produced on the joint. The torque produced on the real joint will be always smaller (ideally equal) than the peak torque measured on the transducer. Therefore, this coefficient can be set to values between 0.1 and 10.
Torque vs time A
Peak value measured on the torque transducer
B
Actual torque measured on the joint
The only way to evaluate the actual torque is to make a residual torque check on the real joint (for instance, by using a STwrench). The relation between the peak torque measured on the transducer and the actual torque on the joint is affected by all the components: The pulse tool, the adapters, the transducer and the joint itself. If any of these components is changed, the relation peak torque – actual torque should be recalculated.
The following process should be used to adjust the pulse tool in order to provide the desired torque on the real joint and to calculate the proper coefficient K:
A
Set a value torque
B
Check the residual torque
C
Slightly increase torque
D
Too low
For instance, assume a target torque for the joint of 100 Nm, and after the tool regulation the residual torque check gives 100 Nm; if the torque measured on the transducer is 120 Nm, in that case the coefficient is 100/120 = 0.83.
Threshold: it is used to filter the trace for proper peak detection for the frequency calculation. After each peak is detected, all the values under the threshold are discarded. This filters all the bounces always present in a pulse tightening.
The threshold can be set from 1 to 99 %. The default value is 80%.
Torque vs time A
Peak
B
Bounce
ACTA pulse strategy
To calculate the tool frequency, the ACTA Pulse Tool strategy uses a set of timers and recalculates the Cycle Start dynamically each time a peak is measured (the Cycle Start is set to the last peak value divided by 1.5).
The parameters that characterize the ACTA pulse strategy are:
Measure delay time: when the torque goes over the cycle start value, the torque is ignored during this Measure delay time. This can be helpful to exclude noise and “false pulses” at the low torque values. The timeout can be set from 0 s up to 5 s. The default value is 0 s (no delay applied).
Torque vs time A
Cycle start
B
Transducer full scale
C
Measure delay time
Reset time: after each peak, the reset time defines a time during which the STa 6000 / STa 6000 Plus does not consider the torque trace. This can be helpful in order to avoid considering as two real peaks the real peak and the bounces possibly produced by the peak itself.
Torque vs time A
Peak
B
Bounce
C
Reset time
The value of this parameter depends on the frequency of the pulse tool and on the bounces possibly present in the trace. The timeout can be set from 0 s up to 5 s. The default value is 0 s (no reset time applied).
End cycle time: when the torque goes and remains below the Cycle complete for the end cycle time, the test ends.
Torque vs time A
Cycle complete
B
Transducer full scale
C
End cycle time
Joints check testing
The quality control strategies are used to check tightening operations already performed, by executing the residual torque check operation.
In the following a description of different strategies.
Residual Torque/Angle
This strategy evaluates the residual torque on a joint, looking for the residual point of the Torque / Angle trace.
A | Cycle start | B | Minimum torque |
C | Maximum torque | D | Breakaway = Residual |
A | Cycle start | B | Minimum torque |
C | Maximum torque | D | Breakaway |
E | Residual |
Define the torque limits such that the residual point is OK in the result.
The Final angle monitoring torque, which must be greater than the Cycle start, defines the point from which the device algorithm starts analyzing the torque/angle trace. This is useful to filter all the noise that may occur at low torque value, and that could be detected as a false residual point.
Torque result:
If the residual point is detected, the result is associated with the residual point; the test is OK if the residual falls within the limits.
If the residual is not detected or the torque goes over the maximum torque, the torque result is the maximum value. Therefore, if the maximum value falls within the limits, the torque result is still OK, but the overall result is marked as Not OK.
If the torque goes over the Change Screw value, the residual is no longer detected and the torque result is the maximum torque.
In the configuration of the residual torque/angle strategy, there are two advanced parameters:
Breakaway angle threshold: it specifies the maximum angle for the residual torque (measured from the Final angle monitoring torque).
Residual angle threshold: it specifies the maximum angle (measured from the Final angle monitoring torque) for the residual torque when a the residual torque is lower than the breakaway point.
If the residual point precedes the Residual angle threshold, the residual torque is detected. this is the normal condition for a residual torque test.
If the residual point is over the Residual angle threshold, the breakaway point is the result of the test. In this case, the Residual angle threshold should be increased to detect the proper residual point.
If the breakaway point is over the Breakaway angle threshold, the residual point is not detected even if the residual point precedes the Residual angle threshold
Residual Torque/Peak
This strategy evaluates the residual torque on a joint as the peak torque necessary to rotate the screw further.
With this strategy, the breakaway point is not detected automatically. Therefore, this is a less objective method of evaluating residual torque. It may be used when the residual torque/time or torque/angle methods cannot be performed.
A | Minimum torque | B | Maximum torque |
C | Torque peak |
Specify the torque limits in order to get a result “OK”.
If the Target Angle is not specified, the angle result is marked as Not Applicable.
If a Target Angle value is specified, the residual torque result is measured at the specified angle (starting from the Final angle monitoring torque) instead of the peak torque:
A | Minimum torque | B | Maximum torque |
C | Target angle |

Traceability Tags
Traceability tags are additional attributes that can be linked to routes in QA Supervisor. If a route is configured with traceability tags, during the test the operator must provide the tags to QA Inspector when requested to. According to how the route's traceability tags have been configured in QA Supervisor, there are different methods and moments in which the tags have to be provided.
Traceability tags can be requested at different Levels within the operation:
Level | Description |
|---|---|
Route | Traceability tag requested either before or after the first measurement of the first inspection in the route, depending on the configured Collection Point. |
Inspection | Traceability tag requested either before or after the first measurement in the inspection, depending on the configured Collection Point. |
Part (piece) | Traceability tag requested either before or after the first measurement of each part/piece in the route, depending on the configured Collection Point. This Level is available only for Forced by Piece Routes. |
Sample | Traceability tag requested either before or after each measurement (sample) in the inspection, depending on the configured Collection Point. |
Traceability tags can be requested in different Collection Points of the specified operation level:
Collection point | Description |
|---|---|
Before | Traceability tag requested before starting a measurement according to the selected Level. |
After | Traceability tag requested after finishing a measurement according to the selected Level. |
Traceability tags can be provided to the system from different Sources:
Source | Description |
|---|---|
Keyboard | The operator has to manually type a text string using the device keyboard when prompted. |
Barcode | The operator has to scan a barcode when prompted. |
Picklist | The operator has to select an item from a Picklist configured for the route when prompted. |
If the traceability tag is configured as optional in QA supervisor, it is possible to skip the requests without providing the tag.
If the Traceability tag on resume option is enabled in QA supervisor, the traceability tag is requested when an incomplete test is resumed.
Traceability tags are not required during the Visual Check with Instruction method.

Glossary
Parameter | Definition |
|---|---|
Angle correction | When the joint design or space limitations preclude use of standard sockets or tools, it may be necessary to use special extension spanners to fit the application. When an extension is used, the angle correction constant permits linear compensation of extension torsion due to the torque applied. It is a fixed additive value. The value is expressed in degrees at the reference torque (Torque nominal). |
Batch size | This parameter specifies how many times the test must be executed. Inside an inspection, this is the number of results expected to complete the inspection. |
Breakaway threshold | It specifies the maximum angle for the residual torque (measured from the Start Final Angle). Over this angle the test result is marked as “not detected”. |
Change screw at | Over-torque threshold that generates an alarm during the test if passed. The alarm notify to the operator that the over-torque applied has damaged the screw. The screw replacement is recommended. This must be higher than the Final Torque max value. |
Cm index | The Cm index describes machine capability; it is the number of times the spread of the machine fits into the tolerance width. The higher the value of Cm, the better the machine. |
Cmk index | The Cmk index describes the capability corrected for position. It is not much use having a high Cm index if the machine setting is way off center in relation to the middle of the tolerance range. A high Cmk index means, then, that you have a good machine with a small spread in relation to the tolerance width, and also that it is well centered within that width. If Cmk is equal to Cm, the machine is set to produce exactly in the middle of the tolerance range. |
Cp index | The Cp index describes process capability; it is the number of times the spread of the process fits into the tolerance width. The higher the value of Cp, the better the process. |
Cpk index | The Cpk index describes the process capability corrected for position. It is not much use having a high Cp index if the process setting is way off center in relation to the middle of the tolerance range. A high Cpk index means, then, that you have a good process with a small spread in relation to the tolerance width, and also that it is well centered within that width. If Cpk is equal to Cp, the process is set to produce exactly in the middle of the tolerance range. |
Cycle complete | When the torque goes and remains under this value for longer than the End cycle time parameter, the test ends (click wrench). |
Cycle start | Torque value from which to start the torque measurement. This must be higher than the transducer Minimum Load value. |
End cycle time | This timeout defines the end of the test. |
Filter frequency | Filtering is a digital operation done on the torque values in order to reject measurement noise and to improve the quality of the measurement results. The filter frequency is a value that gives an indication of what the data collector “ignores” from the process it is monitoring. This value should be chosen carefully: a value that is too small (for example 10 Hz) produces a not correct result for the fast tests made on power Tools. On the other hand, a value that is too large (1000 Hz) can be responsible for noisy traces and results. |
Final angle monitoring torque | For control strategies involving angle measurement, it specifies the torque value from which the angle measurement starts. |
Free round | Free rounds before starting the braking; used for some screwdrivers requiring a number of free rounds to reach the proper operating speed before starting the test operation. |
Friction coefficient | Dimensionless scalar value which describes the ratio of the friction force between two bodies and the force pressing them together. The coefficient of friction depends on the materials used. |
Measure delay time | This timeout is used to filter the possible spikes or noise at the beginning of the test. When the torque reaches the Cycle Start value, the timer starts. During this interval the torque is not considered. |
Measure torque at | Point at which the torque value is measured. The two options are: torque peak or angle peak. It defines which value to acquire on the curve as torque result, if on the local max torque or angle at the end of the curve. |
Minimum pulse | Minimum pulse to calculate the Cm-Cmk related to the number of pulses per second. |
Maximum pulse | Maximum pulse to calculate the Cm-Cmk related to the number of pulses per second. |
Ratchet time | Applied instead of the End cycle time when the torque goes below the cycle start but has not yet reached the Minimum torque value. This allows the operator to release the torque for a while and recharge during the test operation. |
Relaxation time | Due to the mechanical relaxation of the wrench, the torque peak detected by the wrench slightly decreases after a short time interval. This parameter allows to adjust the peak detection in case of wrenches that do not save the torque peak, thus reducing discrepancies between the transducer and the wrench torque peak detections. |
Reset time | This timeout is used to filter the possible spikes/bounces after the click-point. When the torque goes below the cycle complete value, the timer starts. During this time the torque trace is not analyzed (any click-point possibly occurring during the reset time is not considered). |
Residual angle threshold | It specifies the maximum angle (measured from the Start Final Angle) for the residual torque when a the residual torque is lower than the breakaway point. |
Slip torque | The slip torque gives the requested drop in torque after the click-point. If the torque drops more than the slip torque, the peak value is considered as click-point; if not, the peak value is ignored. |
Subgroup size | This parameter defines the number of tests (subgroup) necessary to define each point (the average value of the tests in the subgroup) of the SPC charts. |
Subgroup frequency | SPC, the points shown on the X-R chart are the averages of the set of tests defined in the Subgroup size parameter. The Subgroup Frequency parameter defines the frequency of the points considered in the chart and in the SPC rules:
|
Torque correction coefficient | When the joint design or space limitations preclude use of standard sockets or tools, it may be necessary to use special extension spanners to fit the application. In these cases, the wrench measure must be adequately compensated because the factory calibration is made for the standard arm and the extension arm increases the measured torque. The angle measure is also affected by the extensions, due to its specific torsion when the torque is applied. |
Torque threshold | Limit of the torque value. |
Yield point | Increasing a torque on a joint, this is the point at which the elastic behavior ends and the plastic elongation begins. |
Yield stress point | Theoretical point of stress (pressure) beyond which the material loses its elasticity and becomes permanently stretched. |
