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
