WERA Ball Hex Stainless 172mm 022666 L-Type Wrench, Steel, 6.0mm Diameter, Length,

Hex size (mm): 6.0, total length (mm): 172, neck length (mm): 31 High-quality stainless steel L key for hex socket screws. Stainless steel prevents rust. Hex Plus is designed to make contact with the recess (screw depression) over a surface rather than a point, and the contact surface is designed to be wide, so when force is applied, it is dispersed and transmitted, preventing damage to the recess (screw depression) and making it less likely to strip. Minimizes the notch effect and virtually eliminates screw head damage.
