Cadmium Plated or Stainless Steak hardware

[KyBearhawk]

What is everyone using for bolts,nuts, washers, and cables?

[X'N]

AN hardware only please!

I like mine medium rare myself...

What application are you referring to?

[alaskabearhawk]

Look in AC 43-13B

Galvanized cables are stronger and cheaper. Generally stainless screws provide a more troublesome corrosion situation than cadmium, so I've read.

To add to that stainless has an issue galling in nutplates and strip out easier.

Our local A&P takes out stainless and replaces them with steel precisely because of that.

Cad plated hardware and galvanized cables for mine.

You will want to use Cad Plated AN hardware and galvanized control cables.

I spent the day studying AC43.13 on the whole Stainless STEAL not STEAK question and I never saw anywhere in the document talk about Stainless hardware but yet you see them for sell with AN numbers in stainless steel. And had I not asked or read that section I would naturally assume that Stainless was the better choice.

[X'N]

just an fyi Cad coating is about the best all around material that has the least chance of dissimilar metal corrosion potential.

Personally, I like steak better than steel. But what Eric said, cad plated AN hardware and galvanized cable. You can buy AN hardware assortments on ebay at a reasonable price and have some handy.

KyBearhawk,
The thing to realize is that for "structural" applications (which is basically all of the uses in the bearhawks) we use the CAD plated steel. The reason is that the steel alloys used are stronger than the various stainless alloys. The CAD plating is applied for corrosion protection. Typically the places that you will choose to use stainless is in the non-structural areas such as the various screws that are used to hold cowlings, inspection plates, etc... where the anti-corrosion properties are most important (or the look!) There is not just one kind of stainless either. If you look at the stainless screw sections in aircraft spruce you will find some labeled structural. These have almost twice the modulus as the "other" stainless screws. They still aren't a substitute for the CAD plated but they are more resistant to stripping the head with a screwdriver.
