Radius Corner Hex Body Insert w/Sealed Head

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 below. 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. Contact EFC International directly for design configurations and materials/finishes not specified below. KEY BENEFITS:Weathertight to 50PSI (3.4 bars) Spin Out Resistance in punched hex holes Avoid Stress Fractures and prolong punch & die lifeSuperior Thread Strength from internal rolled thread manufacturing processThreads Gauge before & after installation, preventing thread dilationReduce Inventory - 250% larger grip range than standard rivet nutsSuperior 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. (Special Installation tools are available at EFC-Automation.com, or EFC International directly) NOTES: Grip Range can be affected by parent material density & actual hole size. Trial installations are recommended to determine optimum grip. Underhead seals reduce standard grip range based on seal thickness. Grip Call Outs listed are based on the standard parts without seals; Grip Ranges shown are specific to Sealed Inserts.TOLERANCES: (Hole Size Across Flats) +.004in/.10mm(HD)
