About Turnbuckles and End Fittings

Zinc-plated steel and galvanized steel are mildly corrosion resistant.

Aluminum is lightweight and has good corrosion resistance.

18-8 stainless steel has good corrosion resistance.

316 stainless steel is the most corrosion resistant and has excellent resistance to chemicals and salt water.

Forged bodies and components are stronger than cast and wire drawn bodies and components.

Oval eyes provide more room to attach connectors.

316 stainless steel is the most corrosion resistant and has excellent resistance to chemicals and salt water.

Forged fittings are stronger than wire drawn fittings.

Oval eyes provide more room to attach connectors.
