The AH-TYPE RADIUS CORNER HEX BODY INSERT provides exceptional spin out resistance in punched hex holes and is recommended for use with mating thread-locking fasteners. The radius corners of these inserts expand and fill the corners of a hex hole. (Avoid stress fractures of your material and prolong punch and die life by specifying a radius corner in your hex hole.) These inserts are available with either standard Open End (as pictured), or Closed Ends for leakage protection past the threads. For complete weathertight security, we also offer a variation with a foam seal under the head (listed in the Blind Threaded Inserts section of this Engineering Guide). Radius Corner Hex Body Inserts are designed to be used with Grade 5 or Metric Class 8.8/9.8 mating screws, and can be installed either prior to or after finish. For varying degrees of corrosion resistance, these inserts are offered in several material/finish options to suit your needs. Please contact EFC International directly for design configurations and materials/finishes not specified below.
