High-quality L-key set for hex screws in a practical clip closure made of wear-resistant material, allowing for secure storage of the L-keys and easy removal. L-keys with Hex-Plus profile provide a larger contact surface in the screw head, minimizing wear effects and nearly eliminating the risk of damaging the screw head slot. The ball head on the long arm enables reliable work even in difficult installation situations. The BlackLaser surface treatment ensures excellent surface protection, even against corrosion, and guarantees a long service life. The tools are quickly accessible thanks to the laser-engraved and wear-resistant size markings on the L-keys.
