The Park Tool SW-42 is the four-sided spoke wrench for nipples with 3.45 mm wrench flats. The Park Tool SW-42 four-sided spoke wrench for 3.45 mm nipples has the same size as the classic SW-2, but its head grips the nipple on four sides instead of three.
Design and materials are those of the classic three-sided Park Tool spoke wrenches; the difference is the four-sided shape, which adds strength and support to keep the wrench from slipping and the nipple from deforming. It is made in the USA, heat treated and nickel plated, with a vinyl coating that shows the size at a glance.
SW-42 or SW-2: which 3.45 mm spoke wrench to choose
- Same size: both work on 3.45 mm (0.136") nipples.
- The SW-2 is the classic three-sided wrench; the SW-42 has a four-sided head.
- The four-sided grip gives more support and helps avoid deforming the nipple.
- This size is found on many department store and low-to-midrange bikes: always measure the nipple before working.
Why choose Park Tool SW-42
- Four-sided head for more strength and support on the nipple.
- Reduces slipping and deformation compared to a three-sided wrench.
- Heat treated and nickel plated for a long workshop life.
- Vinyl coating that identifies the size immediately.
If you want the SW-2 size with a more secure grip, the Park Tool SW-42 four-sided spoke wrench for 3.45 mm nipples is the upgrade to keep on your bench.
