Are these hardened steel & corrosion resistant?

Asked by: sweeneyuk
The Screw-Tite screws have been hardened in a way that gives a perfect balance of ductility & strength. Like all Zinc & Yellow screws they do possess a certain amount of proctection but if you want the extra corrosion resistant you could look at the Timber-Tite, Deck-Tite screws in Net-Coat Green which give a superior protection. Or if you are working within a marine type environment you can use the Deck-Tite Plus (316 Stainless steel) screws for ultimate corrosion resistant.
