What is PEM screw?
PEM® brand fasteners utilize self-clinching, broaching, flaring, surface mount, or weld technology to provide strong, reusable, and permanent threads and mounting points in thin sheet metal, P.C. board materials, and other ductile or non-ductile thin material.
How strong are PEM nuts?
PEM SH nuts are engineered to install into high-strength steel sheets at 975MPa maximum ultimate tensile and as hard as HRC 30 or less on the Rockwell “C” scale. Host panels can be as thin as 1.4 mm / . 056”.
