Description Hosco Original Phillips Head Truss Rod Wrench. It is the final solution to adjust a traditional slotted truss rod nut with a “ ” shape wrench, not an “-” shape. We design only an 11mm short length x 9mm diameter head to use the wrench without taking off the neck. “ ” shape can catch the slotted nut perfectly and disperse turning torque evenly. It is the “must-buy” tool for guitar setup.
