Wheel bolt grade

[CS_Rally]

Eric,

I don't think McMaster sells full threaded M16 in fine pitch. They have with
2mm pitch if I remember correctly.
BTW, I would use Grade 12. It's better to err on the high side in this case.

If you can source them locally, could you tell me how much?

Cheers,

Carlos.

ps. I bet you can source them in Canada.
