SL locknuts are self-clinching fasteners with a deformed-thread locking feature that provides 3-cycle prevailing torque performance, suitable for applications requiring cost-effective locking against vibration. They are designed for use with steel socket head cap screws of 180 ksi / property class 12.9 and are recommended for sheet materials with hardness of HRB 80 or less or HB 150 or less. The fastener maintains its locking strength up to 800°F / 426°C, though temperatures above 300°F / 149°C will dehydrate the conversion coating. The part is constructed of heat-treated carbon steel with a thermal oxide finish and light oil coating.
Type SL self-locking nuts are designed with a unique and economical TRI-DENT® locking feature, which meets demanding locking performance requirements.
