The CHA-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 requires a blind hole with a diameter of 0.213 in. and a minimum mounting depth of 0.312 in. The stud is compatible with aluminum sheets having a hardness of HRB 50 or less and leaves the opposite side of the sheet smooth and unmarred. Installation is performed using a standard press with a PEMSERTER or similar tool. The design satisfies ingress protection requirements by maintaining a sealed surface.
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.
