BSOA-440-12 is a blind-threaded, self-clinching standoff designed for installation into sheets of aluminum with a Rockwell B hardness of 50 or less and a Brinell hardness of 82 or less. It features a through-hole thread size of #4-40 and a length of 0.375 inches (12 in 32nds). The standoff installs permanently into metal sheets as thin as 0.025 inches (0.63 mm) and provides a closed-end barrel for flush mounting. It is made from hardened stainless steel, and the optional nickel plating can be specified with the NC suffix for corrosion resistance. The minimum hole size is 0.040 inches, with a minimum edge distance of 0.187 inches. The product belongs to the PEM® self-clinching standoff series, engineered for permanent mounting in thin sheet metal without access to the rear side.
These standoffs, which use the proven self-clinching design, install with a squeeze in properly sized round holes - and become permanently mounted in the thin sheet.
When blind-threaded types are used, outer sheet surfaces are not only flush, but closed as well.
