The TORX® bits feature color coding for easy size identification. Designed for use with impact drivers and suitable for applications on hard materials. Stainless steel construction for long-lasting performance, with a torsion zone that effectively distributes force concentration. The torsion zone absorbs maximum torque values, making the bits more resistant to wear from sudden impacts, preventing premature tip breakage, and increasing their lifespan.
