The Park Tool SW-42 is a precision-engineered spoke wrench designed for professional mechanics and home bike enthusiasts who require superior grip when truing bicycle wheels. By utilizing a unique four-sided contact design, it significantly reduces the risk of rounding or deforming aluminum spoke nipples during tension adjustments, offering a more secure fit than traditional three-sided tools. While it provides excellent stability, users should be aware that this specific model is sized exclusively for 0.136-inch (3.45mm) nipples, making it less versatile for wheels utilizing different nipple sizes.

Yes, it works well with brass nipples, but it is specifically designed to provide the extra support needed to protect more delicate aluminum nipples.
Yes, the SW-42 is designed to fit the exact same 0.136-inch (3.45mm) size as the red SW-2.
No, this tool is precision-sized for 3.45mm nipples only. Attempting to use it on different sizes will damage the tool or the spoke nipples.
The SW-42 is finished in red, which is the standard Park Tool color code for 0.136-inch nipple wrenches.
Wipe it down with a clean, dry cloth after use. If it becomes greasy, use a mild degreaser and dry thoroughly.
Verify the nipple size is exactly 0.136 inches (3.45mm) and check for dirt buildup on the nipple or inside the tool head.
Ensure the wrench is pushed fully onto the nipple to engage all four sides; do not use if the nipple is already partially rounded.
The SW-42 is compatible with most standard bicycle wheels using 0.136-inch (3.45mm) nipples, sharing the same sizing specifications as the industry-standard SW-2. Before use, verify that your wheel nipples are indeed 3.45mm, as using this tool on larger or smaller nipples will lead to improper fit or damage. To maintain the tool, keep it clean from grease and road debris to ensure a positive grip. After extended use, periodically inspect the internal faces of the wrench for wear; while built to last, the precision of the four-sided interface depends on the tool remaining free from physical deformities.
