CFHA-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), providing a reusable #10-32 thread. It installs using a standard press into a blind hole with a recommended minimum depth, leaving the opposite sheet surface smooth and unmarred. The stud is specified for use in materials with hardness up to HRB 70 / HB 125 and requires a minimum hole diameter of 0.213 in and minimum edge distance of 0.185 in. Installation is achieved with a PEMSERTER press or equivalent.
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.
