BSOS-M4-16 is a blind-threaded, self-clinching standoff designed for permanent installation in thin metal sheets, providing a flush, closed-end mounting surface. It features an M4 x 0.7 thread and a length of 16 mm, with a minimum hole size of 4.8 mm and minimum edge distance of 7.9 mm. The part is made from hardened stainless steel and is suitable for use in stainless steel sheets with a Rockwell 'B' hardness of 88 or less. Its closed-end barrel ensures no protrusion on the reverse side. The designation implies optional nickel plating for corrosion resistance, as indicated by the absence of an NC suffix requirement in the part code structure, consistent with SO4-type variants described for stainless steel applications.
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.
