   How much weight can a Grade 8 bolt hold?

   • If we take the 150,000 PSI and multiply it by .0491”, we get 7,365 lbs. So a Grade 8 bolt that’s ¼” in diameter should be able to hold a load of roughly 7,365 lbs. Here are some other approximates for parts of other common sizes: To expand on this even more, a Chevy Suburban weighs about 5,800 lbs.
