The SK Hand Tool 7 piece, 12 Point SuperKrome Fractional Short Combination Wrench Set features a high-polish SuperKrome finish for work environment protection and maximum corrosion resistance. The SureGrip wrenching design on wrench box ends, drives the side of the hex of the fastener, not the corner, to increase torque and avoid edge breakage, especially on rusted or damaged fasteners. Box ends are also countersunk to help lead the wrench over fastener heads. Heads are angled 15 degrees for greater access. Open ends feature a smooth arc radius design for improved strength and durability. Made in the U.S.A. Set contains: SuperKrome 12 Point Fractional Short Combination Wrenches: 3/8", 7/16", 1/2", 9/16", 5/8", 11/16" and 3/4".
