Blind-threaded self-clinching standoffs designed for mounting into metal sheets, featuring a closed-end barrel for flush mounting and no protrusion on the blind side. The BSO series is recommended for use in steel or aluminum sheets with a Rockwell B hardness of 80 or less, and the 6440 thread code indicates a thicker wall for increased bearing surface and reduced risk of panel damage. Installation requires a minimum hole size of 0.040 inches and a minimum distance to edge of 0.27 inches. The 28-length code corresponds to 0.875 inches in total length. These standoffs are not suitable for stainless steel sheets without additional consideration.
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
