CLS-M3-5-2 is a self-clinching nut designed for permanent installation in aluminum or steel sheets, providing high pushout and torque-out resistance with a serrated clinching ring to prevent rotation after installation. It is dimensionally equivalent to NASM45938/1 specifications. The part installs into sheets compatible with the CLS series, which is rated for use in materials with specified hardness limits, though exact thickness or thread pitch for this variant is not stated. The nut features a metric M3 thread and is intended for use with Class 3A/4h or Class 2A/6g screws.
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.
