High quality and seem super strong. I did not feel like I had to worry about breaking a bolt while torquing them with odd ratchet and wrench setups due to difficulty in reaching them. I did do a re-torque after a few heat cycles and a few of the bolts did need to be snugged back down. Unsure if that was a result of not enough torque during initial install or if they backed out, but no issues since then. Overall happy with these.

5.7L header bolts. 7/16 flange these were perfect length. I chased my threads with a tap first...made everything much easier. Especially considering some of these bolts are hard to access. These are meant for headers not exhaust manifolds. I think that's why people are saying they don't fit.

Not as described these do not fit the exhaust header for a 2017 ram 5.7 I tried returning and postage has to be paid by me which was 30 dollars
