Nuts too big!

Something weird has happened!
I have two pairs of Velocity Aeroheads wheels and I’ve been swapping them between two bikes.
The nuts for one front wheel are now too big…
I know that rear axels are bigger than front but I’ve taken the wheel to GEAR and looked through all of their nuts and still couldn’t come up with something that is the right size…

Any ideas what size will fit?

what do you mean too big

won’t bite! slip threads when tightening

are you using a rear one on a front axle? or have you stripped the threads on the axle without noticing?

Seeing I have been to a bike shop and gone through a lot of different sizes I reckon it might be stripped :frowning:
