Park Tool HCW-15 Headset Wrench 32/36mm

The Park Tool HCW-15 Headset Wrench features Park’s proven Y head design and all headset wrench openings are lazer cut to ensure a tight, accurate fit. Precise sizing is achieved by high voltage computer controlled lazer technology after heat treat. Waiting until the wrench is heat treated eliminates shrinkage and expansion of the steel after the wrench is sized. It takes longer, and costs more, but it’s worth the extra effort. The HCW-15 has a 32mm and 36mm wrench.
