Manifold & Down-pipe Brass Nut. 5/16" UNF.  (Sold as a Set of 6)   GHF261-SetA

Brass nut 5/16" UNF standard length for exhaust manifold or combined inlet/exhaust manifolds:

Sold as a Set of six Brass Nuts

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
