CSOS-832-5 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), leaving the reverse side smooth and unmarred. It installs using a blind hole with minimum depth and requires a HAEGER® or PEMSERTER® press for proper fixation. The standoff features an 8-32 thread and is made from 300 series stainless steel with no finish, suitable for sheet materials up to HRB 70 / HB 125 hardness. Installation and performance data align with the CSS/CSOS series, including a maximum installation punch load of 440 lb for aluminum and 5,300 lb for cold-rolled steel, and tightening torque of 18 in-lb. The part meets ASME B1.1 and ASME B1.13M thread standards.
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.
