Work with the same quality tools as service technicians with the STEELMAN 78340 15mm Combination Wrench with 6-Point Box End. Constructed of heat treated chrome vanadium steel alloy this tool is guaranteed to meet or exceed ASME and ANSI torque standards to give you the long lasting durability you require from your tools. Size callouts are stamped into the steel both vertically and horizontally on both sides of the wrench to make identification easy. A mirror-polish chrome plating covering provides rust and corrosion resistance and is easy to wipe clean when soiled with oil and other workshop grime. The open end on this combo wrench is angled 15-degrees to provide increased leverage and easier access to fasteners in tight places. Similarly, the box end has a 15-degree offset to provide your fingers with that little bit of extra clearance that they need as you work. The 6-point box design grips the sides of fasteners and not the corners to provide maximum torque transfer with a reduced chance of rounding off fasteners.
