Self-Clinching Nuts – Types S, SS, CLS, CLSS, SP

Self-clinching nuts are installed by placing them in properly sized holes in sheets and applying a parallel squeezing force to the head of the nut. The sheet metal surrounding the head cold flows into an undercut thereby making the fastener an integral part of the sheet. A serrated clinching ring prevents the fastener from rotating after installation. Provide load-bearing threads in thin sheets with high pushout and torque-out resistance. Type CLA is recommended for use in steel or aluminum sheets HRB (Rockwell “B” scale) 50 or less and HB (Hardness Brinell) 82 or less. Types CLS / CLSS are recommended for use in steel or aluminum sheets HRB (Rockwell “B” scale) 70 or less and HB (Hardness Brinell) 125 or less. Types S / SS are recommended for use in steel or aluminum sheets HRB (Rockwell “B” scale) 80 or less and HB (Hardness Brinell) 150 or less. Type SP is recommended for use in stainless steel sheets HRB (Rockwell “B” scale) 90 or less and HB (Hardness Brinell) 185 or less.
