The CSS-832-8 is a concealed-head self-clinching standoff designed for permanent installation in steel or aluminum sheets as thin as 0.062 in. It provides a threaded hole for mating hardware and allows the opposite sheet surface to remain smooth and unmarred. It requires a blind hole with a diameter of 0.172 in. and a minimum mounting depth of 0.290 in. for installation. The fastener is installable using a standard press and satisfies strict ingress protection requirements. It is rated for a maximum tightening torque of 18 in-lb in cold-rolled steel and 5,300 lbf installation pullout force in cold-rolled steel, and 4,000 lbf in 5052-H34 aluminum. It meets NAS63540/4 specifications.
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.
