Spoke Wrench Park Tool SW-40 Black 3.23 mm

Spoke Wrench Park Tool SW-40 Black 3.23 mm

The Park Tool SW-40 is a high-quality spoke wrench for 3.23 mm spoke nipples. It uses Park Tool’s well-known ergonomic shape and premium materials, while the unique four-sided wrench design provides extra strength and support to help prevent slipping and deformation of nipples.

Each SW-40 is made in the USA, heat treated and nickel plated for long service life, even with regular workshop use. The black vinyl coating allows the size to be identified at a glance and also improves grip during use.

This size is often found on higher-end bikes and is typically compatible with many common nipple brands, including DT Swiss, Sapim, Wheelsmith, Pillar and others. Always measure the spoke nipple first to ensure the correct fit.
