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-). WebA prevailing torque nut is any type of lock nut that has a prevailing torque to assist in preventing self loosening. Technically speaking, nylon insert locknuts fall under this …
WebNOTE: The prevailing torque value is that required to thread the nut onto the bolt. It's a measurement to ensure the locking mechanism is working as designed. Do not confuse this with final torque, which is that used to … Webprevailing-on torque torque to rotate the nut on its mating externally threaded component with the torque measured while the nut is in motion and with no clamp force 3.4 prevailing-off torque torque to rotate after backing off the nut until the removal of the clamp force in the externally threaded component in the following 360° rotation of ...
WebDec 8, 2011 · 1-Prevailing Torque Type Lock Nuts: All metal prevailing torque type lock nuts achieve their prevailing torque by altering the shape of the nut in some way – most commonly by distorting the threads of the nut which then bites into the mating part when tightened. These include: 2-way reversible lock nuts, Flex-Type Lock Nuts, Stover Lock …
WebPrevailing torque is the amount of torque needed to screw a locking nut down a thread.
