Product Description
The BSO-440-18ZI is a self-clinching blind threaded standoff designed for permanent installation in thin metal sheets. By utilizing a proven self-clinching design, this fastener is installed by pressing it into a round hole using a standard squeeze action, which causes the sheet material to cold-flow into the pilot. The blind-thread feature is a vital attribute, ensuring that the outer sheet surface remains flush and closed, providing a clean, unmarred appearance while effectively sealing the assembly against environmental contaminants. Manufactured from heat-treated carbon steel with a zinc finish, it is ideal for applications requiring specific spacing and secure component mounting in
Sealed Barrier: Blind threading keeps the external side of the panel flush and protected from debris, dust, or moisture.
Permanent Attachment: Becomes an integral part of the metal sheet once installed, eliminating the risk of loose hardware falling into sensitive electronics.
High Performance: Offers superior pushout and torque-out resistance in metal sheets as thin as .040 in.
Streamlined Assembly: Simple press-in installation reduces the need for secondary operations like welding, tapping, or the use of extra nuts.
Extended Spacing: Provides a precise .562 in standoff height for consistent internal component clearance and stacking.
