Wera 867/1 Impaktor Torx Screwdriver Bits

This variant of the Wera 867/1 Impaktor is a T40, 50mm bit supplied in a pack of 5, built for the most demanding heavy-duty applications where a large Torx profile and extended reach are both required. The T40 is specified for high-torque industrial, automotive, and structural fastening tasks, and the 50mm length adds valuable reach when working with longer fixings or in deeper access points. Wera's Impaktor technology ensures these bits withstand the extreme torsional forces of impact drivers, whilst the rough diamond-particle coating delivers a tenacious grip on the screw head — dramatically reducing cam-out risk and preserving both the bit and the fixing even during prolonged heavy use.
