Blind-threaded self-clinching standoffs for mounting, spacing, or stacking panels, installed permanently into metal sheets as thin as 0.63 mm with a flush, closed-end profile. The BSOA series features a thicker wall for increased bearing surface, reducing risk of cracking in mating components. Designed for use in steel or aluminum sheets with Rockwell B hardness of 70 or less, or Brinell hardness of 125 or less. The part number BSOA-6440-12 indicates a length code of 12 (0.375 inch) and a #4-40 thread size, with a minimum hole size of 0.040 inch and minimum edge distance of 0.187 inch. No active grounding features or nickel plating are included by default.
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.
Standoffs with thread codes offer greater wall thickness
