The Titleist 910 wrench is used to adjust 910 drivers, fairway woods, and hybrids with SureFit technology. Titleist 910 clubs feature a tour dual-angle hosel system to optimize ball flight, higher or lower and for more draw or fade. These adjustments are made using the Titleist 910 Wrench which provides the correct amount of torque to the hosel screw to tighten it securely for play. Does not include the carrying case.
