Park Tool SW-42 4-Sided Spoke Wrench - 3.45mm | Red

What makes the Park Tool SW-42 a shop-friendly spoke wrench?

The Park Tool SW-42 4-Sided Spoke Wrench is a 3.45mm nipple wrench built around a four-sided engagement design that provides more contact area and better grip than traditional two-notch wrenches. Color-coded red for fast identification, the hardened steel body sits squarely on the nipple flats, reducing the slippage that rounds corners when applying tension during truing or wheel builds.

The four-sided socket interface means you can engage the nipple from more positions as you work around the wheel, speeding up the process and reducing hand fatigue. For shops doing regular wheel service or riders who true their own wheels at home, the SW-42 sets a higher standard for fit and function in a simple but critical tool.
