An eye hook is also known as an eye bolt and it is a mechanical fastener that has a threaded shaft and the head is in the shape of a ring. Eye hooks are used for attaching an eye to a certain structure through which you can secure ropes, cables, and shackles. They are also commonly used to create a lifting eye which helps to attach a crane to machinery, with a specific purpose of lifting eyes that are rated safe for the workload.
When lifting certain machinery, it is a common practice to screw the eye hooks inside a tapped hole in the structure. For this, you will need an eye bolt that is fully threaded up to the shoulder. When the eye hook needs to be inserted through a hole and then fastened by a nut on the other side, it is efficient if there is a shank present. A shank is an unthreaded area of the shaft that is present below the shaft and it offers a better transfer of load into the hole surface and there is less risk of cracking under some severe pressure.
Low-Strength and High-Strength Eye Hooks
Low-Strength Eye Hooks
Low-strength eye hooks are normally produced from the length of a bar and with a diameter that is nominal to the thread size. The head is bent into a ring from the unthreaded area of the bar. These types of bolts are suitable for axial loads but not for off-axis loads. The opening where the bar is curved to form the ring shape may be welded but it can potentially fail at such a point.
High-Strength Eye Hooks
High-strength eye bolts have produced heads that ordinarily incorporate a significant shoulder. The shoulder empowers them to help huge off-pivot loads. The capacity to help off-hub loads is frequently significant in lifting applications where lifting slings with various legs are utilized to join numerous lifting eyes.
Special Types of Eye Bolts
Anchor Eye Bolts
These are special types of eye hooks or eye bolts that consist of some anchor bolts that can be used to fasten into masonry structures.
These are similar to eye bolts but they consist of a wood screw instead of a machine screw. Screw eyes are utilized to effectively attach an eye to wood and plastic structures. Small screw eyes can be used to hang curtain wires and frames.
These are nuts that perform similar functions as an eyebolt but are sometimes identified as eye nuts in certain catalogs.
This is another form of an eyebolt that consists of a captive ring passing through the eye of the head, and creating two chain links. This can minimize bending forces on an eyebolt to a great extent.
Pigtail Eye Bolts
These are framed from the length of a bar, like standard low strength eye bolts, yet the head is bowed into a helix with the goal that it doesn't completely close on itself however can go on beyond 360 degrees. This permits the center of a rope to be strung into the eye without expecting admittance to an end.
These are designed in a way to effectively guide a cable or a rope so that they can pass smoothly with less friction. The head consists of four rollers assembled in a way through which the rope can pass smoothly.
