Groove depth

To clarify it's the groove across the shaft of the axle I'm inquiring on
Sorry, I misunderstood the question. Still waking up.

Thanks DD, would you think I could test out both by interchanging axles or would this contaminate the assembly. When you have prepped a wheel and axle I assume they should stay marred together or I would risk getting the funk inside there when I take one out and put in another??
