What is a Turnbuckle?
A turnbuckle is a device used for tensioning wire, rope, chain, and other support lines. They are frequently used in rigging, architecture, and marine applications.
Constructed from a long sleeve with internal screw threads and two threaded end fittings, this tool lets you easily manipulate your anchor points. Just rotate the turnbuckle body to pull them closer together or push them apart.
Turnbuckle hardware can be manufactured using galvanized or stainless steel. We carry a full line of end fitting styles, including jaw jaw, eye eye, hook hook, eye jaw, and hook eye in various sizes.
Heavy-Duty Turnbuckle Benefits
Our hot dip galvanized and 316 stainless steel turnbuckles have high quality hardware fittings. Designed for durability, they are a valuable component in the boat and marine rigging industries.
The galvanized style has forged elongated eyes to minimize stress on the eye fitting and make attachment to sailing hardware easier. They are meant for straight or inline pulls only, and the jaw features either a nut/bolt or pin/cotter pin to secure the device to cabling.
Shop by Brand
Our wide selection of turnbuckles includes both domestic and import options. While the majority of our customers prefer those made in the USA, imported hardware is ideal if you are looking for a more economical choice. Both options meet federal specifications.

Top Materials for Heavy-Duty Turnbuckle Parts
Stainless Steel - 316L stainless steel turnbuckles offer high corrosion resistance and durability with standard UNC threading to interchange hardware. They offer the highest resistance to high chloride or high moisture environments.
Pipe - Pipe turnbuckles are an offshoot of stainless steel tensioners. Unlike standard hardware, the body is enclosed in stainless steel pipe for cosmetic reasons (such as wire railings so that threads are not visible). It's UNC threaded so the fittings can be interchanged with standard turnbuckle fittings.
Galvanized - Galvanized turnbuckles use hot dip galvanized steel for durability, resistance to corrosives, and weather-resistance. Made for in-line or straight pull applications only.
Turnbuckle Hardware Options
There are a large variety of turnbuckle end fittings available to fit your specific rigging needs, whether you are connecting to wire rope, chain, or another type of line.
Deck Toggle
A "T" shaped bar sits inside a mounting bracket with holes on either side. This configuration allows the assemblies to rotate 180 degrees within the mounting bracket. It's often used to attach to deck posts.
Drop Pin
These tie downs have a rotating pin on the end that flips flat into the body of the pin to thread through a hole. They can then be extended perpendicular to the body for a secure hold. This end fitting offers an excellent clean look.
Eye
These solid loop ends have no vulnerable connection points to allow cable to slip through. The elongated eye version minimizes stress on the components.
Fork or Jaw
These are rigging turnbuckles with wishbone-shaped anchor points. They are fitted with a nut and bolt or pin and cotter assembly. This type of fitting is ideal for situations where the anchor point is fixed and will not work with an eye or where the anchor point needs to be secured from slipping off the fitting.
Hook
Chain turnbuckle hardware shaped in an open hook. Hooked ends may open the same direction or in opposite directions, depending on your rigging requirements. This fitting offers the quickest option for attachment and release.
Lag Screw
The threaded screw end allows for permanent, secure attachment to your anchor points.
Stub End
These are used where a connecting point is not needed - instead, they can separate or push apart objects.
Swage Stud
Swage stud fittings offer a solid corrosion-resistant endpoint that is threaded to accept wires directly into the fitting and swaged to secure them permanently. This style is used to connect rope ends that don't have an end fitting.
Threaded Rod
Turnbuckle hardware end fitting with standard threads that easily form a direct connection to a post or other mounting surface.
