Concealed-head, self-clinching studs and standoffs designed for thin metals

PEM® concealed-head, self-clinching studs and standoffs from PennEngineering® install permanently in thin metal assemblies to provide strong and reusable threads for mating hardware while preserving a smooth appearance on the side of the sheet opposite installation. The concealed-head feature satisfies ingress protection requirements in assemblies where a sheet must remain completely sealed from air, liquid, dust, and gases.

The fasteners install in steel or aluminum sheets as thin as 0.062 in. Studs (aluminum or stainless steel) are available in thread sizes #4-40 through #10-32 and M3 through M5 and in lengths from 0.250 through 1 in. Standoffs (stainless steel) are offered in thread sizes #4-40 through 1/4-20 and M3 through M6 and in lengths from 0.187 through 1 in.
