Blind Threaded Standoffs - Types BSO, BSOA, BSOS - Unified
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.
