Blind-threaded self-clinching standoffs designed for flush, closed-end mounting in metal sheets, with a thicker wall for increased bearing surface to reduce damage to mating components. These standoffs install permanently into sheets through a round hole and are suited for applications requiring no exposed threads on the back side. The BSOA series is recommended for aluminum sheets with a Rockwell B hardness of 50 or less and Brinell hardness of 82 or less. The 8632 thread code indicates a #8-32 thread with a 0.164 inch nominal hole size and a minimum distance to edge of 0.31 inch. The standoff height and thread length are determined by the product code suffix, with 18 corresponding to a length of 0.562 inches. These standoffs are made from hardened stainless steel. Minimum hole size is 0.164 inches, and the counterbore diameter is 0.312 inches.
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.
If you require a standoff which we do not offer in this bulletin, please contact us. We will be happy to work with you to satisfy your special need.
Standoffs with thread codes offer greater wall thickness
