1. What is Turnbuckle Hardware?

A turnbuckle also is known as rigging screw, tensioner, straining screw, barrel strainer, or adjuster, is a device for adding or releasing the tension or length of ropes, cables, tie rods, and other tensioning systems. They are used for rigging or tensioning wires, ropes, rods, etc., typically within industries such as oil and gas, construction, shipping, mining, and fishing. You can easily twist the turnbuckle body to expand or contract the length, without rotating the end fittings on both sides.

2. Components of Turnbuckles

2.1 Body

The body of a turnbuckle is the central component that connects the end fittings. It is usually a cylindrical or hexagonal metal bar with internal threads. The body’s length determines the maximum extension or contraction of the turnbuckle.

2.2 End Fittings

The end fittings of a turnbuckle are the components attached to the cables, ropes, or rods. They come in various shapes, such as jaws, eyes, or hooks, and provide the means for secure attachment and adjustment.

2.3 Threads

The threads on the turnbuckle body allow for easy rotation and adjustment. They can be right-handed or left-handed, depending on the specific application and requirements.

3. Turnbuckle Material

The most common turnbuckle materials are carbon steel and stainless steel. We usually add a zinc layer on the carbon steel galvanized turnbuckles with protection against rust and corrosion, while stainless steel turnbuckles can be used in high chloride or high moisture environments, as they offer a higher level of corrosion protection. If corrosion is a concern, stainless steel turnbuckle is your best choice.
