PEM® Type SL™ self-clinching steel locknuts from PennEngineering® integrate a unique TRI-DENT® locking feature to hold mating screws tight over time by providing sufficient torsional resistance to withstand vibration, thermal cycling, and other disruptive forces that could loosen the screws in service. These prevailing torque locknuts, which meet 3 cycle locking performance to effectively “self-lock” the threads of mating screws, further will allow for the screws to be removed and re-attached repeatedly as needed without compromising the locking threads.
