CLS-348-2 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 is compatible with sheets of specified hardness and installs using a parallel squeezing force that causes the sheet material to cold-flow into an undercut around the head. The part belongs to the CLS series, which is recommended for use in steel or aluminum panels meeting specified hardness limits. All CLS nuts in this series feature non-locking threads and are dimensionally equivalent 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.
