PARKTOOL SW-4.2 4 SIDED SPOKE WRENCH 3.4MM

The Park Tool SW-42 uses the same world famous design and high quality materials as our three-sided spoke wrenches, with a unique four-sided wrench design for extra strength and support to help prevent slipping and deformation of nipples. Each SW-42 is made in the USA, and is heat treated and nickel plated for long service. Park Tool spoke wrenches are vinyl dipped to indicate the size at a glance.

• Sized for spoke nipples with 3.45 mm (0.136") wrench flats
• Equivalent to Park Tool SW-2
• This size is often found on most department store bikes, as well as many other low-to-midrange bikes — always measure to be sure
