Jaw & Jaw Rigging Screws
Rigging screws are used to provide a means for length adjustment and for tensioning. They are also used with guys for masts, towers, other structures and engineering applications. Rigging screws generally have elongated eyes or clevis (Jaw) end fittings for connection to shackles, wire rope assemblies, pad eyes and the like. A central cross-hole is provided at the inner end of the thread and at each end of the body, which permits visual observation of the maximum permitted extended position of the end fitting. Rigging screw bodies are formed from tubular sections of steel and can have an almost infinite size range and scope for length adjustment. Size and adjustment of rigging screws is limited by the available end fittings. Additionally, rigging screws have the innate facility for continuing lubrication as the enclosed section of the body provides a suitable reservoir for grease or other lubrication. Hence, they have an advantage in relative corrosive applications such as ships rigging and permanent outdoor guys.
Rigging Screws and Turnbuckles in accordance with Australian Standards are available in various grades. The standard Nobles grade of supply is Grade P. Other grades (S and L) are available and some stocks may be held in specific sizes.
