CSOS-032-6 is a stainless steel 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 opposite side smooth and unmarred. It requires a blind hole of minimum depth and is installed using a press with compatible HAEGER® or PEMSERTER® tooling. The fastener meets ASME B1.1 2B internal thread specifications and is passivated for corrosion resistance. It is recommended for use in sheets with hardness up to HRB 70 / HB 125. Installation tooling includes HAEGER® anvil part number H-109-10/M4L and PEMSERTER® punch part number 975200048. This part is part of the CSS/CSOS series, which shares concealed-head design, installation method, and material properties with other variants.
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.
