The GEARWRENCH QuadBox double box ratcheting wrenches give you 4 sizes on 1 wrench reducing tool count and making more space in your tool box! There are 2 sizes on each box end. The reversing levers on both sides and ends allows for fast and easy access to turning fasteners in either direction without having to remove the 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 a 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. The 0° offset on both ends of the wrench provides greater access to fasteners in the tightest spaces. The 85227 is a 2 piece metric set that includes 2 QuadBox wrenches in sizes 8 mm, 10 mm, 12 mm, 13 mm on the first wrench, and 16 mm, 17 mm, 18 mm, 19 mm on the second wrench.
