Rundown Selftap, Thread Cutting To Torque

The Selftap - Thread cutting to torque function enables tightening where the rundown torque required is greater than the Rundown complete torque, for example when tightening thin layers of metal using self-threading (or selftapping) screws. The selftap window starts when the torque value reaches SelftapTorqueMin/2. The torque must exceed SelftapTorqueMin, but not exceed Selftap-Torque-Max, during the angle window.
