Self-clinching nuts of the S and SS types provide load-bearing threads in thin steel or aluminum sheets with high pushout and torque-out resistance. They are designed for installation in materials with a hardness of HRB 80 or less and HB 150 or less. The fasteners install permanently by cold flowing sheet metal into an undercut beneath the head, with a serrated clinching ring to prevent rotation after installation.
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 and SS are recommended for use in steel or aluminum sheets HRB (Rockwell “B” scale) 80 or less and HB (Hardness Brinell) 150 or less.
