Increase in assembly productivity



When elements are joined using hexalobular (TX) fasteners, the force is transmitted over a large surface area across the flanks of the drive rather than being centred on one point, as is the case with hexagon socket drives, for example. This has a number of advantages:


  • Reduced tool wear

  • Tool does not slip because force is distributed optimally

  • No damage to surface coating

  • No wobbling

  • Screw locates securely


Hexalobular drives must comply with DIN EN ISO 10664


  • As a result, connection elements with hexalobular heads are standardised and can be used all over the world

Notice
  • Head dimensions in ISO 14581 countersunk screws are gauged in accordance with ISO 7721

  • Some screws with short dimensions are threaded up to the head, see ISO 14581

  • Countersinks for screw heads in accordance with ISO 14581 must comply with ISO 15065
