Review for Park Tool HCW-6 Head/Crank Wrench – 2019
32mm head wrench and 15mm pedal wrench. Our popular and versatile Head Wrenches feature our 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 its worth the extra effort.
