Concealed-head self-clinching studs, including type CHC-032-6, install permanently in steel or aluminum sheets as thin as 0.062 in. (1.6 mm) to provide reusable #10-32 threads. Installation requires a blind hole of specified diameter and depth, and leaves the opposite sheet surface smooth and unmarred. These studs are recommended for use in materials with hardness of HRB 70 or HB 125 or less. They install using a standard press and are designed to meet ingress protection requirements by sealing the sheet. The part number CHC-032-6 is not explicitly listed, but the series CHC family is fully described with corresponding dimensions and material requirements.
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.
