CFHC-032-6 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. It installs via a blind hole with a minimum diameter of 0.205 in. and a minimum depth of 0.312 in., leaving the opposite sheet surface smooth and intact. The stud is manufactured from 300 series stainless steel with a passivated finish, suitable for sheets with hardness up to HRB 70 / HB 125. Installation requires a standard press and compatible tooling, with inserts flush to the sheet surface. The part supports ingress protection requirements by maintaining a sealed mounting interface.
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.
