• AH-Type Radius Corner Hex Body Inserts

    AH-Type Radius Corner Hex Body Inserts provide exceptional spin out resistance in punched hex holes and are recommended for use with mating thread-locking fasteners. The radius corners of these inserts expand and fill the corners of a hex hole. (These insert can help avoid stress fractures of your material and prolong punch and die life by specifying a radius corner in the 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 heading "Blind Threaded Inserts" in this section of the Encyclopedia.

  • Low Profile Knurled Threaded Inserts

    The Low Profile Knurled Threaded Insert features a knurled body with a smaller diameter, reduced profile head to provide virtually flush installation without special hole preparation. Countersink drilling or dimpling of the parent material can be eliminated. During insertion, the knurled body expands 360° to fill the hole, creating exceptional torque strength and resistance to vibration. A backside flange is also formed, even in multiple thicknesses of materials without any need for adjustments. These inserts are to be used with Grade 5 or Metric 8.8/9.8 mating screws. All sizes available are listed on this page, in a representative sampling of materials, finishes and end options (Open Ends for most versatility, and Closed Ends to eliminate leakage past threads).

  • AL Type Blind Threaded Inserts

    AL Type Inserts have a knurled body with a low-profile, large diameter head for maximum all-around strength and spin out resistance in drilled or punched holes. During insertion, the knurled body expands 360º to fill the hole, creating exceptional torque strength and resistance to vibration. A backside flange is formed, even in multiple thicknesses of materials without any need for adjustments. These inserts are to be used with Grade 5 or Metric 8.8/9.8 mating screws.

  • AL Type Knurled Inserts with Large Sealed Head

    The Knurled Insert with Large Sealed Head combines all the features of the standard knurled inserts plus weathertight security provided by a PVC foam seal bonded to the underside of the head. These sealed inserts will withstand 50 PSI (3.4bars) of pressure and can be used in punched or drilled holes. During insertion, the knurled body expands 360º to fill the hole creating exceptional torque strength and resistance to vibration. A backside flange also forms, even in multiple thicknesses of materials without any need for adjustments.

  • AO Type Small Diameter Low Profile Blind Threaded Inserts

    Small Diameter Low Profile Blind Threaded Inserts have reduced profile heads and smaller diameter bodies to provide excellent spin out resistance in smaller holes or close to edge applications. During insertion, the insert's body expands 360º to fill the hole, thus creating exceptional torque strength and vibration resistance. A backside flange is also formed, even in multiple material thicknesses, without any need for adjustments.

  • AT Type Knurled Blind Threaded Inserts for Thicker Panels

    These Knurled Inserts for Thicker Panels have tiny knurls under their head, and are designed to be installed into most materials over 0.030in/0.76mm in thickness. Their reduced length makes them ideal for limited clearance applications. They can be installed using lightweight, handheld pneumatic tools that can be located at any position in your assembly sequence. As the insert is installed, the threaded nut portion is drawn into the upper sleeve portion. This 360º swaging action expands the sleeve to firmly hold the insert in position in the hole. They are to be used with Grade 8/Metric 12.9 mating screws.
