CHC-032-10 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), offering a reusable #10-32 thread. It installs flush with the sheet surface, leaving the opposite side smooth and sealed, suitable for ingress protection applications. The stud requires a blind hole of 0.210 in. diameter and minimum depth of 0.312 in., with a minimum edge distance of 0.210 in. from the hole center. Made from stainless steel, it is recommended for use in sheets with hardness up to HRB 70 / HB 125. Installation is performed using a press with a hollow anvil and solid punch.
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.
