CFHA-032-6 is a concealed-head self-clinching stud designed for permanent installation in aluminum sheets as thin as 0.062 in. (1.6 mm) to provide a reusable #10-32 thread. It installs flush with the sheet surface, leaving the opposite side smooth and unmarred, and meets ingress protection requirements by sealing the hole during installation. The stud requires a blind hole of 0.213 in. diameter and minimum depth of 0.312 in., and is recommended for use in aluminum with hardness HRB 50 / HB 89 or less. Installation is performed using a PEMSERTER press or standard press.
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.
