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. Extra-hard. ¼” hexagon, suitable for holders as per DIN ISO 1173-D 6.3.
