Abstract:

A square drive recess was found to provide better properties for corrosion prone fasteners than a hex drive. Coating systems were evaluated by long term environmental tests simulating the deck near steam catapults. A thick coating of electroplated nickel and cadmium was found to provide superior protection to fasteners installed in steel or manganese bronze structure. Launch valve studs and nuts with a thick electroplated nickel coating were able to survive laboratory tests at 700 F in a corrosive environment. Inconel 718 alloy fasteners also survived the tests and provided superior properties. Author
