BSOS-3.5M3-14 - Blind Threaded Standoffs by PennEngineering ® (PEM ® )

The PEM® BSOS-3.5M3-14 is a metric blind threaded self-clinching standoff engineered to create high-strength, reusable internal threads in thin metal sheet materials. Constructed from premium 300 Series stainless steel, this fastener features a specialized self-clinching design that integrates into round installation holes using a standard press, fully eliminating the need for tapping or welding. Its signature blind-threaded barrel guarantees that the exterior surface of the target panel stays entirely closed and flush, ensuring a clean aesthetic profile while completely isolating internal assemblies from screw penetration and external contaminants.

Efficient Self-Clinching Mechanism: Compresses smoothly into pre-drilled round holes using any standard squeeze tool, lowering production costs by bypassing sheet-tapping processes.

Sealed Blind-Thread Design: Provides a fully enclosed thread barrel that keeps the opposite side of the hosting panel completely flat and flush, safeguarding sensitive internal electronics.

Durable Stainless Steel Body: Fabricated using high-grade 300 Series stainless steel to ensure long-term corrosion resistance and industrial-grade longevity.

High Torque-Out Resistance: Locks permanently into the host sheet metal to deliver exceptional hold and prevent hardware spinning during final assembly.

Passivated Protective Finish: Treated with a standard factory passivation process to satisfy rigorous structural cleanliness and performance regulations.
