Blind-threaded self-clinching standoffs install permanently into metal sheets, providing flush, closed-end mounting with internal threading for component attachment. These standoffs are designed for sheets with a minimum hardness of HRB 80 or HB 150 and support metric threads including M3. The minimum hole size for M3 threads is 4.22 mm, with a nominal counterbore diameter of 6.4 mm and a minimum distance to edge of 4.8 mm. The series includes hardened stainless steel variants suitable for demanding applications.
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.
