Turnbuckles & Rigging Screws

Turnbuckles and Rigging Screws are common rigging components used to connect rigging and apply tension to your cables and wire ropes.

Also known as Straining Screws, they typically consist of two threaded shanks that terminate in various end fittings such as eyes, bolt shackles, forks, and wages, and are available with open or closed barrels, with various end fittings including jaws, eyes, hooks, closed eyes, or even a combination of both.

Various material and finishes are on offer from Lifting Equipment Store, including hot-dip galvanised, self-colour, or stainless steel, the latter perfect for Marine and Outdoor applications.


Turnbuckles originate from the Aircraft Industry, where they have historically been utilised for tensioning structural wires for aircraft wings - perfectly illustrating the structural integrity of these products.

Rigging Screws and Turnbuckles are seen as one of the quickest and most effortless means of tensioning your cable and wire ropes. Tension is adjusted by simply turning the main-frame to increase or release the strain of the cable/rope. This is ideal in multiple applications are you wouldn't be having to twist either the eye bolts or the cables -  a painless operation that cuts out the trivial process of removing cables and restraining the load in order to gain the correct tension for the application.

The main difference between a Turnbuckle and a Rigging Screw is that a turnbuckle features an open body, meets US standards, and are measured imperially in inches. In contrast, a Rigging Screws is designed with a closed body and are measured metrically in millimetres.
