Posting this here since we dont have a specific hardware/fastener forum.
I dont know if anyone here has experience with shopping from these guys. Looks like a nice crowd but they only ship to the USA. Still a family business I am sure Bob G would know them.
But what i wanted to share that anyone can get hold of by download is the link to their various excellent charts. Take a look i am sure you will save or print more than a few of them for your shop.
