The Powerbuilt 13 Piece Metric Long Arm Magnetic Hex Key Wrench Set is a top-quality key wrench set offering strength, precision, and organization. Each wrench is constructed of premium chrome vanadium steel for durability and precise fit into hex head fasteners. For added versatility, wrenches also feature ball ends that drive fasteners from angles up to 25 degrees from vertical and helpful magnetic ends for retaining loose fasteners. The nonslip powder coating creates a better grip gives added protection and color-coding. The longer arms have a more extended reach and generate more torque than standard length key wrenches. Set includes common wrench sizes 2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 10mm, 12mm, 14mm, 17mm, and 19mm. The 13 key wrenches are organized with size markings inside the fold-out plastic carrier you can toss in a toolbox. Powerbuilt products meet or exceed ANSI standards. Dependable enough to last a lifetime.
