Self-Clinching Nuts – Types S, SS, CLS, CLSS, SP
Type S, SS, CLS, and CLSS nuts provide load-bearing threads in thin sheets with high pushout and torque-out resistance.
Type SP, PEM 300® nuts provide strong load-bearing threads in stainless steel sheets as thin as .030”.
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.
