CHC-832-6 concealed-head self-clinching studs install permanently in steel or aluminum sheets as thin as 0.062 in (1.6 mm) to provide reusable threads for mating hardware. The stud's head remains flush and unmarred on the opposite side of the sheet, enabling smooth finishes and sealed enclosures. Installation requires only a blind hole of 0.290 in diameter with a minimum depth of 0.289 in for aluminum or 0.219 in for steel. The part, sized for #8-32 thread, is designed for use in materials with hardness up to HRB 70 / HB 125. It installs using a standard press and meets NAS63540/4 specifications when ordered accordingly.
These studs ensure permanent mounting in metal sheets as thin as .062 in.
The fastener head is locked securely in a blind, milled hole and is able to handle substantial loads. The concealed-head feature allows the side of the sheet opposite installation to remain smooth.
Sheet preparation only requires a milled blind hole to the recommended minimum depth. Center-cutting end mills for hole preparation are available from PennEngineering. Installation of the concealed-head studs and standoffs is simple using a hollow anvil and solid punch. Place the head of the fastener in the hole and insert using any standard press. Displaced sheet metal flows smoothly around the head into the undercut.
