Wera 860/1 XZN Vielzahn screwdriver bit designed for internal multi-tooth (XZN) screws.

The single bit has a length of 25 mm and is sized to provide precise fit and reliable torque transfer for professional and DIY tasks.

Advantages

The 1/4" hex shank ensures compatibility with standard bit holders and quick-change systems, while the 25 mm length balances access and control.
