CSOS-032-12 is a concealed-head self-clinching stainless steel standoff designed for permanent installation in steel or aluminum sheets as thin as 0.062 in. (1.6 mm), providing a smooth, unmarred surface on the opposite side of the sheet. It installs using a blind hole with minimum depth and requires a HAEGER® or PEMSERTER® press with specified anvil and punch tooling. The standoff features an external thread compliant with ASME B1.1 2B and ASME B1.13M 6H standards, and is passivated per ASTM A380. It is rated for use in sheets with hardness up to HRB 70 / HB 125. Installation ensures sealed ingress protection (IP) integrity. The part is part of the CSS/CSOS series, which shares the same installation method and performance criteria as other concealed-head standoffs in the PEM® line.
These standoffs 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.
