Screwdriver Bit Wera 860/1 XZN Vielzahn

Wera 860/1 XZN Vielzahn screwdriver bit designed for internal multi-tooth (XZN) screws. Made for universal use, the bit combines toughness and wear resistance with a 1/4" hex shank compatible with holders to DIN ISO 1173-D 6.3. 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 bit is manufactured to deliver a secure fit in Vielzahn (XZN) fasteners and minimize cam‑out and wear. Its zähhart (tough-hardened) construction increases durability under repeated use. The 1/4" hex shank ensures compatibility with standard bit holders and quick-change systems, while the 25 mm length balances access and control.
