Blind-threaded self-clinching standoffs install permanently into metal sheets through a blind hole, providing flush, closed-end mounting. The BSO series is designed for use in steel or aluminum sheets with hardness up to HRB 80 / HB 150. The 5M3 thread size indicates a metric thread with a 3.5 mm nominal diameter and 0.6 mm pitch. The part has a minimum hole size of 5.39 mm, a barrel outer diameter of 7.9 mm, and a length of 18 mm. Minimum distance to sheet edge is 6.8 mm. A thicker wall provides increased bearing surface to reduce risk of panel damage.
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
