Park Tool HCW-15 32/36mm Headset Wrench

The Park Tool HCW-15 wrench features the proven "Y" head design and laser cut openings to ensure a tight, accurate fit. Precise sizing is achieved by high voltage computer controlled laser technology after heat treat. Waiting until the wrench is heat treated eliminates shrinkage and expansion of the steel after the wrench is sized. Although it takes longer and costs a little more, it's worth the extra effort. Size: 32mm and 36mm.
