Metric Stainless Steel Multi-Colour Ball End Hex Key Set, 9 Piece - 3950/9 - 

High quality Hex Key set made 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 “round the corner" screwdriving. "Take it easy" Tool Finder: colour coding according to size. In an almost wear-free hex-key clip fastener.
