Unthreaded Thru-Hole Standoffs

The self-clinching, unthreaded, thru-hole standoff is ideally suited for fast and repeatable insertion via use of any standard mechanical, hydraulic, or pneumatic press. They are well suited for use as spacers between multi-layer panel assemblies. JHP Fasteners stocks these industrial fasteners in sizes and materials that will satisfy virtually any industrial or commercial application.

Application note:
Insertion of these unthreaded self-clinching standoffs can be done via a manual press or via use of an automated pneumatic or hydraulic press. The unthreaded hole will allow a threaded stud to pass directly through the standoff/spacer. When inserted properly, there will be no secondary reaming or deburring required.
