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
Notice

Due to their head geometry, these screws can only be subjected to limited loads, see DIN EN ISO 898-1
