I have already purchased the same bolts/nuts in Grade 8 and will swap them out soon.

These were made in Taiwan (just like every other bolt in the store) but they have the 6 marks on them and were marketed as "SAE Grade 8".

Good luck trying to buy bolts not made overseas. Even when I order bolts from McMaster Carr, they are almost always from China/Japan/Taiwan sometimes Germany for the SS rivets. Unless all these hardware stores are just flat out doing false advertising, I think I will be fine with these overseas bolts. I really hope so because I have used these Grade 8's all over my suspension in various places.

I know how people here feel about all things made in China but that seems to be the way of the world.
