Product Description
The PEM® BSO-M5-12ZI is a self-clinching blind threaded standoff designed to stack or space components while providing a permanent attachment in thin metal sheets. Its closed-end (blind) design features a solid outer wall that acts as a barrier against contaminants, effectively sealing the assembly from dust, dirt, and moisture. This configuration also serves as a positive stop that protects delicate internal components by limiting thread penetration. Installed by being squeezed into a round hole using a standard press, the fastener causes the host material to cold-flow into an undercut for high pushout and torque-out resistance. Once seated, the head remains flush with the mounting sheet, maintaining a clean professional exterior profile without the need for secondary welding.
Closed-End Design: Provides an environmental seal and protects internal circuitry by preventing screw over-insertion and debris ingress.
Permanent Self-Clinching: Becomes an integral part of the assembly, eliminating the risk of loose hardware falling into sensitive electronics.
Flush Installation: The head of the standoff installs flush with the mounting sheet for a smooth, snag-free external finish.
High-Strength Construction: Manufactured from heat-treated carbon steel for reliable performance in steel or aluminum sheets.
Metric Spacing: Engineered to provide a consistent 12mm distance between panels or components for precise hardware alignment.
