CLS-632-0 is a self-clinching nut designed for installation in aluminum, steel, or stainless steel sheets, providing load-bearing threads with high pushout and torque-out resistance. It features a serrated clinching ring to prevent rotation after installation and is compatible with sheets as thin as 0.025 in. (0.64 mm). The part is dimensionally equivalent to NASM45938/1 specifications. It is installed using a parallel squeezing force, causing the sheet material to cold-flow into an undercut around the head. Its installation pushout resistance is rated at 110 lbf in 5052-H34 aluminum and 130 lbf in cold-rolled steel, with a torque-out resistance of 16 in.-lbf in aluminum and 20 in.-lbf in steel.
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.
