CSOS-832-16 is a concealed-head self-clinching standoff designed for permanent installation in steel or aluminum sheets as thin as 0.062 in (1.6 mm), providing a threaded hole for mating hardware while leaving the opposite sheet surface smooth and unmarred. It installs using a blind hole of minimum depth, with the flange flush to the sheet surface upon pressing. The standoff is made of stainless steel with a passivated finish and meets ASME B1.1 2B thread standards. It is rated for a maximum tightening torque of 18 in-lbf in cold-rolled steel and 200 in-lbf in 5052-H34 aluminum. Installation requires HAEGER® or PEMSERTER® tooling, with HAEGER® anvil part number H-109-8/M3.5L and PEMSERTER® punch part number 975200048. The fastener is compatible with sheet hardness up to HRB 70 / HB 125. Distances to edge and hole dimensions are specified per the manufacturer's charts. No aerospace or military certification is explicitly stated for this variant.
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.
