Product Description
The BSO4-632-28 is a self-clinching blind threaded standoff specifically designed for permanent installation into stainless steel sheets. Manufactured from heat-treated 400 Series Stainless Steel, this fastener is engineered to clinch into sheets with a hardness up to HRB 88 on the Rockwell B scale. The blind-thread (closed-end) design is a critical attribute, ensuring the outer sheet surface remains flush and closed, providing a clean, unmarred appearance while effectively sealing the assembly against environmental contaminants. It is an ideal solution for providing extended spacing and secure mounting in stainless steel enclosures where aesthetic integrity and environmental protection are paramount.
Stainless Steel Compatibility: Specially hardened to allow for successful clinching into 300 Series stainless steel panels.
Environmental Sealing: The closed-end design prevents the ingress of dust, moisture, or debris through the fastener hole.
Permanent Attachment: Becomes an integral part of the host sheet once installed, offering high resistance to pushout and torque-out.
Flush Exterior: Maintains a smooth, professional finish on the reverse side of the mounting panel.
Extended Precision Spacing: Provides a consistent 7/8" standoff height for internal component clearance and stacking.
