S™/SS™/SP™ Self-Clinching Nuts

PEM S™/SS™/SP™ Self-Clinching Nuts prevent fasteners from rotating after installation and are installed permanently on aluminum, steel, or stainless steel sheets. The S/SS nuts provide load-bearing threads in thin sheets with high pushout and torque-out resistance, while the SP nuts provide strong load-bearing threads in stainless steel sheets as thin as .030" (0.8mm). PEM S/SS nuts are recommended for use in steel or aluminum sheets HRB 80/HB 150 or less, and the SP nuts are for use in stainless steel sheets HRB 90/HB 192 or less.
