Park Tool Headset Wrench HCW-6 32mm/36mm

Our popular and versatile Head Wrenches feature our proven “Y” head design, and all headset wrench openings are laser cut to ensure a tight, accurate fit. Precise sizing is achieved through high voltage computer-controlled laser technology after heat treatment. 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.

32mm and 36mm head wrench

The HCW-6 is a purpose-built wrench for the installation and removal of pedals, as well as the installation, removal, and adjustment of races on threaded headsets. It features our classic headset wrench design, nickel plated with wrench openings that are laser cut after heat treating to ensure a tight, accurate fit.
