Flat Head Full Hex Body


  • Fully cold-formed, sharp cornered hex body for ultimate spin-out resistance.
  • Minimum body size and counter-bore for minimum application space packaging and mating screw cross-thread avoidance.
  • Thick wall construction for ultimate tensile and push-out strength.
  • Heavy hex design for increased tensile loads.



  • The TW (thin wall) line is designed as a lower cost alternative for applications with reduced load requirements, and with a wider grip range. The Böllhoff TW line is compatible with both spin-spin and spin-pull tooling. The half hex body is a great solution for applications where higher spin out resistance is required.
