Screw turnbuckles are the basic tensioning device that connects two items. They help secure structures to the ground, screen doors flush with openings, set fences on end posts, and many other things. They can provide tension in a fence or perimeter cable, or help build a suspension bridge, straighten a tilted TV antenna, or secure a tractor to a travel trailer.
Like other rigging hardware products, screw fasteners are available in many different sizes, configurations and types. With this article, our goal is to help you gain a basic understanding of screw fasteners, how they work, and how to use them properly in your next project.
The metal frame in the center of the device that connects the two threaded end fittings. The body itself adjusts tension by extending and retracting the end fittings.
The main body can be one of two types: closed or open. The open type is the more traditional type, where the threads are visible through the frame. The body wraps the threads in the closed frame to create a slimmer profile to fit into a more compact space.
Also known as locknuts, nuts can be placed on the threads of the end fitting and tightened against the body of the hub to help prevent the unit from loosening or unthreading.
These are the two connections that screw into the opposite ends of the body of the screw fastener. One end fitting has a right-hand thread, while the other has a left-hand thread. This allows you to turn the body to adjust the tension after installation without having to move the end fittings.
There are three main types of end fittings that can be used together in any combination at either end of the screw fastener.
Hook end fittings are used to create temporary connections because they are easy to connect and disconnect quickly. They should never be used in connections where tension may be accidentally released.
Jaw end fittings consist of jaws and bolts that are held together by nuts or pins. Eye End - An eye end fitting is a closed loop that can be attached to a release buckle or quick link.
An eye end fitting is a closed loop that can be attached to a release latch or quick link. You can follow HAIFAN to find all kinds of end fittings you want.
This is the measurement of the diameter of the threaded portion of the end fitting. The larger the thread diameter, the greater the load carrying capacity of the spline, and vice versa.
