High quality L-key set for hexagonal socket screws in a practical clip fastener made of wear-resistant material, enabling secure storage of the L-keys as well as simple removal. L-keys with Hex-Plus profile offer a larger contact surface within the screw head, reducing notching effects to a minimum and almost completely eliminating the risk of destroying the screw recess. The ball-end on the long arm allows for reliable working even in difficult installation situations. The precise chrome-plated design ensures high corrosion protection. The tools are quickly accessible thanks to the laser-engraved and wear-resistant size markings on the L-keys.
