The Avdel Hexsert provides a blind threaded insert with a hexagonal body, providing high torque-to-turn and pull-out performance, particularly in soft metals. The Hexsert can be used in very thin materials with quick and easy insertion and includes a near flush version.

Key features and benefits

  • Hexagonal section and bore improves torque-to-turn by up to 200% in sheet metal compared to round body inserts
  • Superior pull-out performance
  • Can be used for very thin sheet materials from 0.50mm (0.02")
  • Double diameter body and lead-in chamfer provide easy insertion into hole
  • Access needed from only one side of the application, for high speed assembly
  • Provide a female thread in application
  • Can be installed in pre-coated or post painted applications without damaging the surface
  • Clamp two or more sheets
  • Various platings available to increase corrosion resistance
  • Low profile head allows near flush fit to application and clamps two or more sheets of material together, within the grip range
  • Large flange head provides a load bearing surface and reinforces the hole to prevent push-out. Can be used as a spacer and can be supplied with an underhead seal.
  • Closed end prevents the ingress of dirt and fluids into thread and electrical circuits
  • High strength option available for use with metric bolts and screws up to Property Class 12.9
  • Can be used with hand tools, pneumatic tools and fully automated machines to suit a wide range of assembly methods

Complementary Information

74290 tool for hexagonal hole production
The 74290 tool compliments and extends the range of Avdel hand tools for installing threaded inserts, by offering the capability of producing hexagonal holes for threaded Hexsert® inserts into materials where access is only possible from one side. The 74290 tool allows customers to benefit from the non-rotational properties of hexagonal inserts compared with round inserts. This is achieved by drilling a round hole, then inserting the 74290 tool and forming a hex hole.
