• 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.
