Wera 3950 PKL Hex-Plus SW 4mm Hex Key

Wera 3950 PKL Hex-Plus SW 4mm Hex Key. High quality L-keys constructed out of stainless steel for 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 screwdriving axis thus enabling "round the corner" screwdriving.
