Not really, I assume he picked grade 8 bolts as cheap source I known material but I don't know. For all I know he has a bucket full of them. Should I go to the big B and buy some Zenith bolts or just turn them up from any old black bar? I guess it would probably work.
I have a bolt but no way to measure how hard it is other than a file.
Thanks for the links Chris, some interesting stuff there.
Hi Frank,
The bottom bolt in the picture would appear to be exactly what I am dealing with, necking included ;). I've past the info along....though my BIL may know this it cant hurt to ask.
This may all be for nort*. My BIL replied this morning Keith Wilson is the guy building his wheels. He added that he has found some bolts in USA and is waiting for them to arrive, though isn't 100% sure as yet they are what he needed. Fingers crossed.
