Nut Exhaust Flange Nuts for Early Ford Bronco
These are the correct THIN WALL course thread nuts to bolt up stock exhaust flanges to stock manifolds. Standard nuts use an 11/16 socket making it a tight fit between the exhaust pipe and wall of the socket, This usually allows one side of the 2 bolt flange to be tighter letting the gasket fit tighter on one side making a leak. These new nuts use a 5/8 socket making it easy to tighten them up evenly.
