Blind-threaded self-clinching standoffs installed into metal sheets provide flush, closed-end mounting with threaded barrels for internal engagement. The BSOA series features a thicker wall design to reduce the risk of cracking or cutting into mating panels and is recommended for aluminum sheets with a Rockwell 'B' hardness of 50 or less. The part incorporates a 0.138-32 thread and is available in a 0.875 inch length. The standoff installs into a minimum hole size of 0.050 inches and requires a minimum distance of 0.31 inches from the hole centerline to the sheet edge. The closed-end barrel ensures a flush surface on the sheet's opposite side after installation.
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
