Wera 3950/9 Hex-Plus L-Key Hex Wrench Set – Metric Stainless. High quality L-key set out of stainless steel for hexagon socket screws by Wera. Stainless steel prevents the transfer of extraneous rust. The Hex-Plus profile offers a greater contact surface in the head of the screw. The notching effect is therefore reduced to a minimum and damage to the screw head more or less eliminated. Come with hex ballpoint 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 “around the corner” screwdriving. In an almost wear-free L-key clip fastener.
