The PEM S-RT self-clinching, free-running locknuts feature a modified thread angle, which allows mating screws to spin freely until clamp load is induced during the screw-tightening process. The applied clamp load engages the locknuts’ vibration-resistant locking feature, which secures the screw in place. PEM S-RT locknuts install into aluminum or steel sheets as thin as 0.030 in. and become permanent parts of an assembly.
