Product Description
The BSO-440-10ZI is a self-clinching blind threaded standoff designed for permanent installation in thin metal sheets. Using a proven clinching profile, the fastener is pressed into a round hole using a standard squeeze action, becoming an integral part of the panel. The blind-threaded (closed-end) design is a vital feature that ensures the outer sheet surface remains flush and closed, protecting internal threads from environmental contaminants and ensuring a smooth exterior finish. Fabricated from heat-treated carbon steel with a zinc finish, this standoff provides high-strength mounting and precise spacing for components in electronic and industrial enclosures.
Sealed Barrier: The blind thread keeps the exterior side of the panel flush and protected from dust and moisture.
Permanent Attachment: Becomes an integral part of the metal sheet with high pushout and torque-out resistance.
Flush Finish: Provides an unmarred, smooth appearance on the mounting side of the assembly.
Hardware Simplification: Eliminates the need for secondary operations like tapping or welding and reduces loose hardware.
Durable Performance: Heat-treated carbon steel ensures reliable thread integrity and mechanical strength.
