Product Description
The BSO-M3-10ZI is a self-clinching blind threaded standoff engineered for permanent installation in thin metal sheets. Utilizing a proven clinching profile, the fastener is pressed into a round hole using a standard squeeze action, which causes the sheet material to cold-flow into the pilot. The blind-thread (closed-end) design is a critical 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 metal chassis.
Environmental Barrier: The closed-end (blind) thread prevents the ingress of dust, moisture, or debris through the fastener.
Permanent Attachment: Becomes an integral part of the metal sheet once installed, offering high pushout and torque-out resistance.
Flush Finish: Ensures a smooth exterior panel surface for high-end aesthetic and functional requirements.
Metric Efficiency: Eliminates the need for secondary operations like tapping or welding and reduces the count of loose hardware.
Precision Spacing: Provides a reliable 10 mm standoff height for consistent internal component clearance.
