GearWrench offers the 13-piece XL GearBox Double Box Ratcheting Wrench SAE Master Set, No. 85999. GearWrench XL GearBox ratcheting wrenches feature a zero-degree offset and a slim profile to access the tightest spaces and recessed fasteners. The longer XL beam increases leverage to maximize torque at the non-ratcheting end for breaking loose stubborn fasteners. The ratcheting box end needs as little as 5 degree of swing arc to turn fasteners compared to 30 degrees for standard box end wrenches. Exclusive GearWrench Surface Drive technology reduces fastener rounding.
