# Synchronized Tightenings

It is only possible to use Multistep tightening programs for Synchronized tightening. Synchronization points are used to synchronize the tools in a set-up. At these points, the tools will wait for each other before continuing with the next step in the multistep tightening program.

It is only possible to assign tightening programs to different tools in ToolsTalk2.

Reject Management

When switch to Off:

Action if failure | Description
End all | All channels will end the tightening and report status NOK. The tightening that did not have an error itself will report additional info Terminated by other bolt.
Continue OK | The failing channels will end the tightening with status NOK. The remaining channels will continue with the rest of the tightening program.

When switch to On:

Parameter | Description
--- | ---
Max number of failing steps | Specifies the maximum number of different steps that can fail during the whole tightening. It does not matter if the same step fail more than once, it still only counts as one failing step. If not set an unlimited number of steps can fail.
Action if exceeded | Specifies the action if Maximum number of failing steps is exceeded.
Action if NOK during repair | Specifies the action if a new error (NOK) is detected while a repair is ongoing.
