Product Description
The PEM® BSOS-832-22 is an extra-long, high-reliability unified blind threaded standoff engineered to create deep structural separation inside thin sheet metal assemblies. Utilizing a field-proven self-clinching design, the fastener drops easily into a properly sized round hole and installs permanently with a standard squeezing action, cold-flowing the host metal to achieve superior torque-out and pushout resistance without the thermal distortion or structural weaknesses of welding. Its blind-threaded (closed) pocket prevents mounting screws from passing completely through, ensuring that the opposite side of the sheet metal remains perfectly flush and unmarred for an unbroken external cosmetic finish. This closed geometry also creates a resilient, dust-tight seal, safeguarding sensitive internal electronics from outside debris, air currents, and environmental contaminants. Manufactured from premium 300 Series Stainless Steel, it delivers high structural durability and long-term corrosion protection, making it ideal for deep-stack server enclosures, medical instrumentation, telecommunications housings, and aerospace sub-assemblies.
Self-Clinching Mechanical Lock: Installs rapidly with a standard pressing action to eliminate loose secondary hardware, tapping, or the thermal stress of welding.
Closed-Bottom Blind Pocket: Guarantees that the reverse surface of the host sheet metal remains entirely flat and smooth while sealing the thread chamber from outside contamination.
300 Series Stainless Steel Construction: Forged from high-grade stainless steel to ensure robust mechanical strength and premium protection against rust and oxidation.
Extended Structural Clearance: Supplies a precise 0.687-inch physical standoff gap, optimized for stacking extra-deep multi-layer printed circuit boards or isolating heavy electronic components.
