High quality L-keys for imperial hexagonal socket screws. Hex-Plus offers a larger contact surface within the screw head. This reduces the notching effects to a minimum and almost completely eliminates the risk of destroying the screw recess. The ball-end on the long arm allows for reliable working even in difficult installation situations. The BlackLaser surface treatment provides outstanding surface protection, even against corrosion, and a long service life. The tools are quickly to hand thanks to the laser-engraved and thereby wear-resistant size markings on the L-keys.
