BSOS-M3-18 - Blind Threaded Standoffs by PennEngineering ® (PEM ® )

The PEM® BSOS-M3-18 is a self-clinching blind threaded standoff designed for permanent and secure installation into thin metallic sheets. Utilizing a proven self-clinching design, this fastener installs easily with a constant squeezing force into properly sized round holes, becoming an integral part of the chassis layout. The unique blind-threaded design ensures that the outer surfaces of the thin sheet metal remain completely flush and closed after installation, effectively protecting internal components from dust, debris, and contamination while preserving a clean exterior profile. Manufactured from durable 300 Series stainless steel and passivated for enhanced corrosion resistance, this standoff provides reliable, high-strength load-bearing threads to safely space components in compact electronic and industrial enclosures.

Self-Clinching Design: Installs permanently into thin metal sheets using a simple, parallel squeezing action without requiring welding or secondary tapping.

Blind-Threaded Configuration: Features a closed bottom that leaves the reverse side of the host sheet clean, smooth, and completely sealed against environment ingress.

Flush Exterior Surface: Ensures the outer face of the panel remains entirely flat for a premium aesthetic and streamlined exterior design.

Corrosion-Resistant Construction: Made of 300 Series stainless steel to reliably withstand challenging operating conditions.

High Torque-Out Resistance: Robust engineering prevents rotation or loosening during mating screw installation and field maintenance.
