8mm axles

[Gustav]

Does anyone know what size of nut/threaded section is used on the UE 8mm axles.I'm going to make some 8mm axles for the LST.

If it's more than 5mm are there some 14mm hexes that fit,i'd be using 8x16mm bearings so i doubt they could be much bigger than 5mm anyway for the hex to fit the inner race.

Also any suggestions for material and/or hardening would be much appreciated.I'm guessing tempering will make them too brittle,maybe it's possible to differentially heat treat them to just harden the pin area.

I was going to try to get hold of some spring steel,bad idea?

Thanks.
