Bolts all fit well, and no leaks yet. I used them for a set of headers for my Silverado with a 5.3 L, and the headers had a 3/8” thick flange. The bolts still fit well.

Overall a good product. Allen socket is cheaply made and easily broken. Use your own socket when installing these. Still Holding strong at proper torque.
