The Sealed Radius Corner Hex Body Blind Threaded Insert provides all the spin-resistance features of the Standard Radius Corner Hex Body version in punched holes with the addition of a weathertight PVC foam seal bonded to the underside of its head. This seal will withstand 50 PSI (3.4 bars) of pressure. The radius corners of the body of this insert expand during installation to fill the corners of the hex hole, maximizing spin resistance. A backside flange is also formed, even in multiple thicknesses of materials without any need for adjustments. They are available with either standard Open Ends (as pictured), or Closed Ends for leakage protection past the threads, in a variety of corrosion resistant Materials and Finishes listed.

Features and Benefits N/A
  • Spin Out Resistance in punched hex holes
  • Avoid Stress Fractures and prolong punch & die life
  • Superior Thread Strength from internal rolled thread manufacturing process
  • Threads Gauge before & after installation, preventing thread dilation
  • Reduce Inventory - 250% larger grip range than standard rivet nuts
  • Superior Corrosion Resistance offered by several material/finish options
  • Quality Installation for varying thickness materials needs no adjustment when using special installation tools, locatable anywhere in assembly, before or after finish.
Additional Information N/A For optimal performance, specify a radius corner in your hex hole to avoid stress fractures and prolong punch and die life, and use these inserts with Grade 5 or Metric Class 8.8/9.8 mating thread-locking screws. PVC Foam Seal is not recommended for use with petroleum based liquids.
