CLS-1224-2 is a self-clinching nut designed for installation in aluminum, steel, or stainless steel sheets, providing high pushout and torque-out resistance with a serrated clinching ring to prevent rotation after installation. It uses a thread form compatible with Class 3A/4h or Class 2A/6g screws and is dimensionally equivalent to NASM45938/1 specifications. The part is installed by applying parallel force, causing the host material to cold-flow into an undercut around the head. It is intended for use in materials meeting specified hardness limits, as detailed in the manufacturer's selector guide. The exact physical dimensions and mounting requirements follow standard CLS series design.
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.
