Specification

DIN 34805-2, TX drive, steel 010.9, zinc flake coating silver (ZFSHL)

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

Notice

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