Hook End Fittings for Turnbuckles—Not for Lifting
Galvanized steel fittings have a thick coating for mild corrosion resistance.
18-8 stainless steel fittings have good corrosion resistance.
316 stainless steel fittings are the most corrosion resistant and have excellent resistance to chemicals and salt water.
Forged fittings are stronger than cast and wire drawn fittings.
