Product Description
The PEM® BSOS-0420-16 is a high-performance blind threaded self-clinching standoff designed to establish strong, permanent internal threads in ultra-thin metal sheets. Manufactured from durable 300 Series stainless steel, this fastener features a specialized self-clinching design that integrates into round holes using a standard press, eliminating complex welding or tapping operations. The standout blind-threaded barrel keeps the outer surface of the hosting panel completely closed and flush, protecting delicate components from screw penetration while shielding internal electronics from dust, debris, and external contaminants.
Self-Clinching Installation: Presses smoothly into place with any standard squeeze action tool, reducing production time by eliminating sheet-tapping or welding.
Blind-Threaded Structure: Extends a closed barrel that isolates the screw thread, ensuring the reverse side of the metal sheet remains completely flush and sealed.
Premium Material Construction: Fabricated from 300 Series stainless steel for reliable strength and excellent longevity in demanding environments.
High Torque-Out Resistance: Clinches permanently into the panel to deliver robust resistance against twisting or pushing forces during assembly.
Passivated Finish: Features a standard factory-passivated surface treatment to maximize environmental durability and fulfill strict manufacturing specs.
