Self-clinching nuts are permanently installed threaded fasteners designed to provide strong, reusable threads in thin sheet metal and other ductile materials. These nuts are installed by placing them into properly sized holes and applying a parallel squeezing force to the head. The sheet metal surrounding the head cold flows into an undercut, locking the fastener in place without the need for welding or adhesives. A serrated clinching ring around the nut ensures it will not rotate after installation, providing high pushout and torque-out resistance.
Type SP nuts are made from 400 series stainless steel and are recommended for use in Stainless Steel sheets of HRB 90 / HB192 or less.
