SL locknuts feature a TRI-DENT® deformed-thread locking design that provides prevailing torque for mating hardware, with a 3-cycle locking performance rating. They are designed for use in sheet materials with hardness up to HRB 80 or HB 150. The locking feature is achieved by deforming the last threads on the head side of the nut, and the fastener accepts Class 3A/4h mating screws. Temperature resistance for the fastening strength is maintained up to 800°F (426°C), though above 300°F (149°C) the conversion coating dehydrates.
Type SL self-locking nuts are designed with a unique and economical TRI-DENT® locking feature, which meets demanding locking performance requirements.
