Wera 667/1 IP Torx Plus Bit – 40 IP x 25mm. High quality bits for recessed Torx Plus screws. Torx Plus profile: in comparison to normal Torx profiles the enlargement of the 6 torque-transferring flanks between the tool and the screw is effected by means of an ellipse-shaped profile design and not a circular one. This means that the power applied when screwdriving is spread over a larger area. Higher torque is transferred and the service life of the screw and tool is also enhanced.
