WebTorque Performance Test (WN 900.1) 1 Before testing make sure nut threads are within specified tolerances. 2 Turn the screw into the test nut (max 10 rpm’s) until the patch is positioned within the nut thread. In doing so mea-sure the maximum driving torque (see table, column I). 3 Back off the screw by 90° and then without stopping measure ... Prevailing torque differentiates a locknut from a free spinning nut based on a value of how much torque is required during installation before clamp loading. For example, on a nylon-insert nut, it is the torque needed to overcome the resistance of the nylon dragging across the mating thread. This torque value is usually not very high relative to final installation torque. Tolerance ranges for torque are specified in some standards such as (ISO, DIN, IFI, ASME, SAE, AN-, MS-, NAS- NASM-).
