Product Description
The PEM® BSOS-M3-22 is an extra-long, metric self-clinching blind threaded standoff manufactured exclusively by PennEngineering® to establish strong, permanent internal threads in thin metal sheets. These fasteners install with a squeeze into properly sized round holes, using a self-clinching design that displaces host material to become permanently mounted in the sheet. When these blind-threaded standoffs are used, the outer sheet surfaces remain completely flush and closed. This ensures a smooth, unmarred exterior profile while creating an unbreached physical barrier that isolates internal components and the thread cavity from external dust, debris, and contaminants.
Blind-Threaded Engineering: Keeps the outer sheet surfaces completely flush and closed, safeguarding sensitive interior components from environmental debris.
Self-Clinching Design: Installs permanently into thin metal sheets via a simple squeezing action, completely eliminating the risks associated with loose hardware.
No Welding Necessary: Provides high-strength, robust attachment points without the thermal distortion, panel warping, or surface blemishes caused by welding.
Corrosion-Resistant Composition: Manufactured from 300 Series stainless steel to deliver reliable, long-lasting mechanical performance in demanding application environments.
