Turnbuckles are most commonly used in applications which require a great deal of tension; they can range in mass from about ten grams for thin cable used in a garden fence, to thousands of kilograms for structural elements in buildings and suspension bridges.

Turnbuckles are also used for tensioning a ship's rigging and lashings. This device is also known as a bottle screw in this context.
