The original subject was "Re: Manifold Nuts, Stainless Steel Or Brass?".

The small Continental aircraft engines around 100 HP use brass fine thread nuts. Other than squeeking a little when removing, they always seem to come off okay. On the 150 HP Lycoming, they use course thread and steel nuts (and this is what most seem to want on their Fergusons). I have always favored the Brass as they don't rust. I have bad luck in gauling of SS screws and about the only advantage is RUST. In Florida, rust is the winner. About half of the steel nuts overall on my tractor were about rusted off or else extremely pitted. One wrap with the chisel and they POP off.

Guess that I will use a grade 8 steel nut as they are more rust-proof.

Depends if the stainless is 300 or 400 series. Depends if the bolt is counterfeit. There is a real problem in the market with brittle bolts head stamped or painted to any spec you want. You should be applying 1800F nickel based anti seize on the threads before installation.

I prefer brass. Been used for years and at least they undo cleanly. Haven't had any problems with manifolds coming loose or anything.

Cheers,

Definitely a grade 8 nut or above. Brass nuts do not hold torque values. SS nuts are actually more susceptable to corrosion than steel nuts. In effect, the harder the nut, the less likely it will stick to the stud. Take for example the IH manifold nuts. These nuts are long, and are very very hard, just like any other IH bolt. IH purely made the best bolts in the industry.

If brass nuts wont hold why are all the A and B FARNALLS still running around with brass nuts and the manifolds aren getting loose Ive got some ive had for 20pluss yrs and havent never been off and they are not loose. You can tell after sandblasting for repaint.

Brass work great and I think they hold torque just fine. Otherwise my manifolds would be leaking. If you use steel maybe some hi temp paint would be in order to control the corrosion.
