High-quality Wera flag key for internal TORX PLUS screws. TORX PLUS profile: Compared to the standard TORX profile, the increase in the six torque-transmitting faces between the tool and the screw is achieved through an elliptical rather than circular profile design. This distributes the applied force during screwing over larger surfaces. Higher torque is transmitted, and the lifespan of both the screw and the tool is additionally extended. High torque transmission for small screws. Particularly suitable for changing indexable inserts. The BlackLaser surface treatment provides excellent surface protection, even against corrosion, and ensures a long service life. Multi-component design for an especially good grip.
