CHC-632-10 is a concealed-head self-clinching stud designed for permanent installation in steel or aluminum sheets as thin as 0.062 in. (1.6 mm), providing a reusable #8-32 thread. It requires a blind hole with a minimum diameter of 0.172 in. and a minimum mounting depth of 0.290 in. The fastener installs using a standard press and leaves the opposite sheet surface smooth and unmarred, supporting ingress protection requirements. It is recommended for use in materials with hardness up to HRB 70 / HB 125. The part adheres to the series characteristics for concealed-head studs, with clinching profile and installation method consistent across CHC variants.
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.
