Self-clinching nuts of types S, SS, CLS, CLSS, and SP provide load-bearing threads in thin sheets with high pushout and torque-out resistance. They are installed in aluminum, steel, or stainless steel sheets by applying parallel pressure, causing the sheet material to cold flow into an undercut and form a permanent bond. A serrated clinching ring prevents rotation after installation. These nuts are compatible with sheets meeting specified hardness limits and require screws of Class 3A/4h or Class 2A/6g fit. The series is suitable for use in materials as thin as 0.030 inch (0.8 mm) for stainless steel applications.
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.
