Flat Keyway for Kart Axles. Note that this keyway will fit many axles, not just Righetti! 

Each keyway noted here is a flat keyway, (meaning it fits into a keyway slot rather than drilled holes in the axle) and has the following dimensions:

• 6mm Keyway Width
• 40mm Keyway Length
• 6mm Keyway Height
• Rounded Edges

• This keyway is ideal for non Righetti Hubs mounting onto the axle, that need some additional height (such as OTK hubs).
