A pair of Brass Nuts 5/16" UNF for exhaust manifold or combined inlet/exhaust manifolds:

Brass nuts on the manifold head pipes minimizes the possibility that the head pipe nut (s) will come loose.

The brass nuts expand/contract at a different rate than steel, therefore they are more stable.

Regular brass exhaust nuts are thicker than steel, by approximately 1/8",

therefore they get a better purchase on the stud.


Good brass exhaust nuts are very hard to find.

It is OK to use Steel washers with the Brass Manifold Nuts

5/16" UNF brass exhaust manifold nuts. Extra long  (1 Inch or 25.4mm)

Sold as a pair only
