Park Tool Spoke Key SW-42C - for 3.45mm Nipples

The Park Tool SW-42 features the same world-renowned design and high-quality materials as our three-sided spoke wrenches, but with a unique four-sided wrench design that provides extra strength and support to help prevent slipping and deformation of nipples. Each SW-42 is proudly made in the USA, heat treated, and nickel plated for long-lasting service. Park Tool spoke wrenches are vinyl dipped for easy size identification at a glance.
The SW-42 matches the 3.45mm (0.136") size of the SW-2 (red).
