GEARWRENCH XL GearBox Double Box End Metric Ratcheting Wrenches have a ratcheting box end that needs as little as 5° to move the fastener as opposed to 30° for other 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 fasteners safe and fast. The box end features improved strength from GEARWRENCH's off-corner loading design which reduces fastener rounding. Made from the finest chrome vanadium steel for precision long-lasting tool life, the wrenches come in a blow-molded carrying case that can be hung on a wall or to keep your wrenches organized in your tool box or rollaway.
