CFHC-032-8 concealed-head self-clinching studs install permanently in steel or aluminum sheets as thin as 0.062 in. (1.6 mm) to provide reusable .190-32 threads. The fastener's head remains flush and concealed after installation, leaving the opposite sheet surface smooth and uninterrupted. Installation requires a blind hole of 0.205 in. diameter and minimum depth of 0.210 in. The stud is made of stainless steel and passivated for use in sheets with hardness up to HRB 70 or HB 125. It is installed using a PEMSERTER® press or equivalent with the specified anvil and punch tooling.
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.
