Blind Threaded Standoffs – Types BSO, BSOA, BSOS


Blind Threaded Standoffs – Types BSO, BSOA, BSOS

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.
