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.
- Screw Eyes: 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.
- Eye Nut: These are nuts that perform similar functions as an eyebolt but are sometimes identified as eye nuts in certain catalogs.
- Ring Bolts: 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.
- Roller Eyebolt: 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.
