The Wera High quality L-keys out of stainless steel for imperial hexagonal socket screws by Wera. Stainless steel prevents the formation of extraneous rust. The Hex-Plus profile 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. Hexagonal ballpoint end on the long arm the ballpoint drive profile means that it is possible to swivel the tool axis away from the screw driving axis, thus enabling "round the corner" screw driving.
