The BSO series are blind-threaded, self-clinching standoffs designed for permanent installation in metal sheets as thin as 0.63 mm, providing flush, closed-end mounting. The BSO-440 variant has a minimum hole size of 0.040 in, a nominal thread size of #4-40, and a barrel length of 0.375 in. It is intended for use in steel or aluminum sheets with a Rockwell B hardness of 80 or less. The ZI suffix indicates optional nickel plating for 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.
