WERA (Torx-Plus) driver bits

High quality bits for concave Torx Plus screws. Compared to the normal Torx profile, the enlargement of the 6 torque transmission flanks between the tool and the screw is achieved by an oval instead of circular profile design. This means that the force applied during screw tightening is distributed over a larger area, which results in a higher torque being transmitted and a longer life for the screw and the tool. High viscosity and versatile. Suitable for holders according to 1/4 inch hexagon, DIN ISO 1173-F 6.3.
