The GEARWRENCH ratcheting combination wrenches are the original patented ratcheting wrench! The ratcheting box end is designed to need as little as 5° to move fasteners versus 30° for standard wrenches. The wrenches are made from strong alloy steel with a bright, full polish chrome finish. The ratcheting box end features off-corner loading for a better grip on the fastener and reduces fastener rounding. They’re available in various lengths and styles, including XL length, stubby, flex, stubby flex, and locking flex. Included Sizes: 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 21, 22, 24, and 25mm.
