High Strength Hexsert®

High strength Hexsert provides clamp force comparable to weld nuts and clinch nuts in high torque applications.

The Avdel High Strength Hexsert is a threaded insert which provides a clamp force comparable to weld nuts and clinch nuts in high torque applications. The hexagonal shape and large flange gives the High Strength Hexsert exceptional torque-to-turn strength in thin sheet materials whilst having safeguards against over tightening which can lead to thread stripping and the need for expensive rework.

Key features and benefits

  • Exceptional torque capability
  • High speed assembly
  • Provides high-strength threads in thin materials starting at 0.5mm
  • Increased thread strength
  • If excessive torque is applied, the screw shank should fail before the insert, avoiding over-tightening problems such as thread stripping and expensive rework
  • Installed and retrofitted with standard Avdel handtools, as well as multi-head and auto-feed robotic systems

Assembly applications

  • Tubular steel
  • Hydroformed parts
  • Magnesium castings
  • Aluminum extrusions

Material and finishes

  • Steel Zinc plated to BS 3382 and clear passivated to achieve 240 hours resistance to red corrosion (ASTM B117) Hexavalent Chromium-free

Specifications

  • Sizes: M6, M8, M10 and M12
  • Large flange
  • Hexagon

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.
