GEARWRENCH XL GEARBOX Double Box End metric ratcheting wrenches need as little as 5° to move the fastener as opposed to 30° for standard box end wrenches. The standard box end combined with the long pattern length gives this wrench excellent torque capabilities to break a stubborn, rusted fastener. The ratcheting box end then makes the loosening or tightening of the fastener fast and safe. The box end features improved strength from GEARWRENCH's off-corner loading, which also reduces fastener rounding. The double box end ratcheting wrenches are made from the finest chrome vanadium steel for precision long-lasting tool life. Comes with a blow molded carrying case that can be hung on a wall or to keep your wrenches organized in your tool box or rollaway.
