    I think 1 inch for the length is a little short. 2 inches would be better.

    Are you serious? One of their selling points has always been their strength. Are they stripping out that easy or just from torquing down on them?

    I got these for free from my uncle. He runs a machine shop and had to order 100 min. He filled up his little bin and gave the rest to me. He says they are stronger than a grade 8 bolt and resist corrision better too. I can't complain
