WebTorque-controlled tightening procedure Within screwdriving technology, torque is still used most frequently as the control parameter. The pre-load force resulting from the tightening torque is significantly influenced by the fluctuating coefficient of friction as well as the screwdriving device’s torque spread.

AF4. 30 foot pounds initial to compress … WebTypically the procedure for tightening a compression fitting is specified using the rotation of the nut as the key metric, rather than torque. Compression nuts are threaded, meaning that the number of rotations of the nut is directly correlated to the linear compression of the ferrule, based on the thread’s pitch.
