BSOS-440-10 - Blind Threaded Standoffs by PennEngineering ® (PEM ® )

The PEM® BSOS-440-10 is a high-precision, unified blind threaded standoff engineered to create solid structural gaps within thin sheet metal chassis. Utilizing a field-proven self-clinching design, the fastener inserts into a properly sized round hole with a standard squeezing force, cold-flowing the host metal into its unique retention profile to become a permanent, high-strength fixture. Because it features a blind-threaded (closed) cavity, the opposite side of the metal sheet remains completely flush and unmarred, maintaining a sleek external cosmetic profile while acting as a reliable barrier against dust, air, and environmental contaminants. Manufactured from premium 300 Series Stainless Steel, it provides outstanding pullout and torque-out resistance combined with long-lasting corrosion protection, making it an excellent choice for medical devices, datacom/telecom racks, consumer electronics, and automotive enclosures.

Self-Clinching Integration: Installs quickly with a standard pressing action, eliminating messy welding, tapping processes, or reliance on loose secondary hardware.

Closed-Bottom Blind Design: Ensures the reverse face of the host sheet metal is completely flat, unmarred, and tightly sealed from outside elements.

Premium Stainless Steel: Fabricated from 300 Series Stainless Steel to deliver optimal mechanical durability and superior rust and corrosion defense.

Precision Unified Spacing: Engineered to provide an exact 0.312-inch physical offset height, making it ideal for stacking printed circuit boards or safeguarding delicate.
