Wera 05073921001 Screwdriver Bit PZ 2x25mm

The Wera 867/4 IMP DC SB Impaktor TORX® Bit TX21 x 25 mm (05073921001) is a premium impact-rated screwdriver bit designed for high-torque fastening applications with impact drivers and power tools.

Engineered with Wera’s Impaktor technology, the bit is built to withstand extreme impulse loads and continuous high-torque use, significantly increasing service life in demanding professional environments. Its reinforced structure helps absorb impact forces, reducing wear and improving long-term reliability.

The tip features a diamond-coated surface, which increases friction inside the screw head, improving grip and reducing the risk of cam-out. This ensures precise and controlled driving performance, especially when working with TORX® fasteners in construction, installation, and assembly work.

The bit includes a 1/4" hex shank (DIN ISO 1173-F 6.3 compatible) for use with standard bit holders and impact drivers. Its 25 mm length makes it ideal for compact applications where direct access and short reach are required.
