The CHC-832-10 is a concealed-head self-clinching stud designed for permanent installation in steel or aluminum sheets as thin as 0.062 in. It features an 8-32 thread, a shank length of 0.312 in., and is optimized for use in materials with a hardness of HRB 70 or less. Installation requires a blind hole with a minimum diameter of 0.213 in. and a minimum depth of 0.328 in., and the stud permits flush mounting with the sheet surface while leaving the opposite side smooth. The stud can be installed using a standard press with a PEMSERTER® or equivalent tool. The part aligns with the CHC type, which is recommended for steel applications and meets NAS63540/4 specifications when ordered accordingly.
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.
