SL locknuts are self-clinching fasteners with a deformed thread locking feature that provides 3-cycle prevailing torque performance. They are made from carbon steel and are designed for use in sheets with a hardness of HRB 80 or less or HB 150 or less. The locking mechanism is formed by deforming one or more threads on the head side of the nut to resist loosening under vibration. These nuts are compatible with Class 3A/4h or no smaller than Class 2A/6g screws. They maintain fastening strength up to 800° F (426° C), though temperatures above 300° F (149° C) may dehydrate the conversion coating.
Type SL self-locking nuts are designed with a unique and economical TRI-DENT® locking feature, which meets demanding locking performance requirements.
