The CSS-M3-4 stainless steel standoff from PennEngineering® is designed for permanent installation in metal sheets as thin as 1.6 mm. It features a concealed-head design that allows the opposite side of the sheet to remain smooth, which is beneficial for applications requiring strict ingress protection against air, liquid, dust, and gases. The standoff provides strong and reusable threads for mating hardware, making it suitable for a variety of assembly applications. Installation requires only a blind milled hole to the specified dimensions and can be accomplished using a standard press. The standoff is capable of handling significant loads, with a pullout strength of approximately 890 N in aluminum and 1330 N in cold-rolled steel.
These standoffs ensure permanent mounting in metal sheets as thin as 1.60mm.
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.
