CLS-M4-0 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 installs permanently by cold-flowing sheet metal into an undercut beneath the head, with a serrated clinching ring to prevent rotation. The nut is compatible with thin sheets and meets performance requirements for applications requiring vibration resistance and corrosion protection. The part is dimensionally equivalent to nuts manufactured to NASM45938/1 specifications.
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.
