CHC-032-8 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 #10-32 thread. The stud installs using a standard press into a blind hole, leaving the opposite sheet surface smooth and sealed, supporting ingress protection requirements. It requires a minimum blind hole depth of 0.312 in. and a hole diameter of 0.190 in., with a minimum distance from the hole center to the sheet edge of 0.210 in. The fastener is recommended for use in materials with hardness up to HRB 70 / HB 125. The thread length is 0.312 in., and the head is fully recessed after installation.
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.
