Product Description
The BSO4-440-32 is a self-clinching blind threaded standoff engineered for permanent installation into stainless steel sheets. Manufactured from heat-treated 400 Series Stainless Steel, this fastener is designed to clinch into sheets with a hardness up to HRB 88 on the Rockwell B scale. The blind-thread (closed-end) design is a vital feature, ensuring the outer sheet surface remains flush and closed, providing a clean, unmarred appearance while effectively sealing the assembly against environmental contaminants. This standoff is an ideal solution for applications requiring maximum spacing and secure mounting in stainless steel chassis and enclosures.
Stainless Steel Compatibility: Specially hardened for successful installation into 300 Series stainless steel panels.
Environmental Protection: The closed-end design prevents dust, moisture, or debris from entering the enclosure through the fastener hole.
Permanent Attachment: The self-clinching action creates a permanent bond with the host sheet, offering high resistance to pushout and torque-out.
Flush Mounting: Maintains a smooth exterior panel surface for high-end aesthetic and functional requirements.
Maximum Precision Spacing: Provides a reliable 1" standoff height for consistent internal component clearance and stacking.
