SL™ locknuts are self-clinching fasteners with a TRI-DENT® locking feature that provides 3-cycle prevailing torque performance, designed for applications requiring a cost-effective metal-on-metal locking solution. The locknut is constructed from heat-treated carbon steel and is rated for use up to 800°F (426°C). The locking feature is formed by deforming one or two threads on the head side of the nut to resist loosening under vibration. Installation is suitable for sheet materials with a hardness of HRB ≤ 80 or HB ≤ 150. The product accepts Class 3A/4h or minimum Class 2A/6g mating screws, and the finish includes thermal oxide with light oil. The material temperature limit for the conversion coating is 300°F (149°C), beyond which dehydration may occur.
Type SL self-locking nuts are designed with a unique and economical TRI-DENT® locking feature, which meets demanding locking performance requirements.
