Re: 3/8 shaft, is it strong enough.
Prior to going to half inch hex shafts for everything we almost exclusively made our wheel axels out of 3/8" Grade 8 hex cap screws we still use them quit a bit when they are correct for the application.
As said above the material and the loading are important in determining if this will work which is why we used hardened bolts.
