Blind-threaded self-clinching standoffs install permanently into metal sheets, providing flush, closed-end mounting with internal threads for panel assembly. The BSO series is designed for use in steel or aluminum sheets with hardness up to HRB 80 / HB 150, and features a closed-end barrel for structural integrity. Part BSO-M3-18ZI corresponds to the M3 x 0.5 thread size with a length of 18 in 32nds of an inch, equivalent to 0.562 inches. The part is suitable for clinching into sheets as thin as 0.63 mm and requires a minimum hole size of 4.22 mm and a minimum edge distance of 4.8 mm. The 'ZI' suffix indicates nickel plating for enhanced corrosion resistance.
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.
