Specification

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
