Park Tool Spoke Key SW-18 - for 5.5mm Hex Nipple

The SW-18 features a 5.5mm hex socket and utilizes an extra long (3.25”/85mm) spoke wrench socket, perfect for fitting internal spoke nipples found on many deep section aero rims.

It boasts our dual density, ergonomically designed screwdriver handle for maximum comfort. The outside diameter of the shaft is 8.2mm.

Note: The DT "pro-lock" nipples are sized at 5.5mm.
