Common Turnbuckle Terms:

Body Types:
Closed Body
The turnbuckle bodies are made from hollow tubing and threads of the body are machined out. The threads of the end terminals are protected within the body. The turnbuckle, once adjusted, is usually held in place by nuts on either end. The ones we carry are all 316 stainless steel.
Open Body
These bodies are, as the name implies, open. The threads in the body are at either end and are connected on two sides which leaves the threads of the end terminals exposed. The bodies themselves are either cast or forged and can be made out of various metals. Forged bodies have a higher working load limit. We carry forged bronze (chromed or plain) and 316 stainless steel that in both forged or cast.
Threads:
UNC
Coarse threads.
UNF
Fine threads; preferred for marine use.
End Terminals:
Toggle Jaw
The preferred end fitting for marine use. The fitting acts a a "universal" joint and allows movement and proper lines of force. The fitting significantly helps to reduce fatigue that would ultimately result in the failure of the rig. If ever in doubt on which end fitting to get use this one!
Jaw
Similar to the toggle jaw but movement is only allowed in one direction. Excellent when pull is in only one straight line. Often a "Rigging Toggle" is used in conjunction with a jaw to acheive the same effect as a toggle jaw.
Swage
This end fitting allows the wire rope to be connected directly to the turnbuckle body. Also referred to as a swage stud when used seperately. Swaging is done by squeezing the metal of the terminal around the wire rope with extreme force. On a turnbuckle for a boat, the swage, or "wire end" is usually right-hand thread and the "boat end" is left-hand thread.
Quick Attach®
A "swagless fitting". The best of several mechanical fittings on the market today to attach wire rope. With simple hand tools a person do their own rigging. For more info click here.
Eye
Eye form a round hole for attachments. They can be unwelded, welded, cast, forged, or machined.
Hook
A hook is a hook... bent metal, don't know what else to say.
