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
 
Due to their head geometry, these screws can only be subjected to limited loads, see DIN EN ISO 3506-1
