Wera 867/1 Impaktor Torx Screwdriver Bits

This variant of the Wera 867/1 Impaktor is a T40, 25mm bit supplied in a pack of 10, designed for applications demanding a large Torx profile and high torque capacity. The T40 is typically found in heavy industrial and automotive contexts, including large structural fixings and drivetrain components, where absolute reliability under load is non-negotiable. Wera's Impaktor technology makes these bits genuinely impact-driver-ready, managing the extreme forces involved without the premature failure that plagues standard bits. The rough diamond-particle coating on the tip grips the screw recess with outstanding friction, preventing cam-out and keeping the fixing and the bit in prime condition throughout the job.
