HCW-7 Headset Wrench: 30.0mm and 32.0mm

The Park HCW-7 Headset Wrench is a 30mm and 32mm head 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 laser 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.

• Laser cutting is done after heat treatment to ensure a tight accurate fit
• 30/32mm headset wrench for adjusting most 1" style threaded headsets
