CFHC-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 reusable #10-32 threads while leaving the opposite sheet surface smooth. It requires a blind hole with a diameter of 0.205 in and a minimum mounting depth of 0.312 in. Installation is performed using a press with a hollow anvil and solid punch, with the flange seating flush to the sheet. The stud is made of stainless steel, passivated, and meets ASME B1.1 2A thread specifications. The CFHC type is rated for use in materials with hardness up to HRB 70 / HB 125.
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.
