High quality TORX® L-key. With a locking function: due to the contact force generated by the contact pressure between the tool tip and the screw head profile, the screws are held securely to the tool. Extra long rod. Black Laser surface treatment provides excellent protection, incl. from corrosion, as well as a long service life of the tool. Laser-applied, and therefore wear-resistant size markings help you quickly find the right key.
