Eye Bolts are one of the most common types of rigging gear, and they’re used as a lifting or securement point. Eyebolts, like sling hooks, slings, and shackles, exist in variou
s configurations and designs. As a result, this can help in rigging, anchoring, pulling, pushing, and lifting objects.
An integrated shoulder helps secure heavy-forged bolts with a continuous eye, and industrial sectors use it to raise pretty heavy off-axis weights, without a shoulder, on the other hand, cannot lift massive off-axis weights. Instead, you can use the smaller in tension cables, secure weights, and perform non-load-bearing tasks.
Vertical lifting applications require load-rated, and you should not use them for angular lifting. You can use non-load-rated bolts for tie-down and guided wire applications, and you cannot use them for lifting. When selecting the eye bolt best suited to your needs, keep the rated weight in mind. You may be curious about the various bolts and their use. So, this post covers it all for you. Keep reading to find all your answers.
Shouldered Eye Bolts
Eye Bolts with a shoulder design are similar to the “shoulder pattern”. This is because these bolts come with a shoulder where the eye and the shank meet. When you place the shoulder in the load correctly, this shoulder design will decrease bending strains on the shank and allow the eye bolt to perform the task of angular lifting.
To perform correctly, you may use it for sideloading or angle loading, but make sure the shoulder is perfectly flush. In addition, always adhere to the manufacturer’s requirements, which may include capacity reductions due to different loading angles.
Non-Shouldered Eye Bolts
Non-shouldered bolts or “simple pattern” are synonymous. You can only use it for fully vertical or in-line lifts because they don’t have a shoulder. Non-shouldered bolts are not helpful for side or angular loading.
Forged Eye Bolt
In electric power lines or overhead lines, forged eye bolts are commonly used to support thimbles, links, clevises, and dead-end insulators on wooden poles. A drop forged eye bolt is another name for it. One or more square nuts can help secure the eye bolt when you use it across a wooden pole.
Bent Eye Bolt
Bent, turned eye, or wire eye bolts, come from a single bent or curved piece and help create the eye. Bent eye bolts are mainly suitable for light-duty applications, and you must not use them for strong loads that might force the eye to open or angular loads that could bend or break the bolt.
Collar Eye Bolts
An oversized collar is present between the eye and the screw thread on these. They’re perfect for axial-loading situations requiring two or more lifting points. The collar’s strong connection to a machined face provides eye support and prevents screw thread bending. There is also little leverage due to the small eye size. Wire tensioning and the secure connection of unevenly weighted weights are only two uses for these.
Nut Eye Bolts
The bottom of the shank juts through the bottom of the load with these eye bolts, and a nut fastens it to its place. Forge, wedge, or bent eye processes can help you make shouldered or non-shouldered nut.
Carbon Steel Eye Bolt
The carbon steel bolts use a mixture of iron and carbon, where the inclusion of carbon results in an improvement in the bolt’s hardness and strength. Manganese is occasionally used to improve the material’s strength. However, carbon bolts are more difficult to weld than steel-based counterparts, resulting in lower elasticity.
Galvanized Metal Eye Bolt
Zinc, along with galvanized metal bolts, helps keep them from rusting. When you immerse the bolt in a molten zinc solution in the hot-dip galvanizing process, it forms the galvanized metal eye bolts. It also prevents corrosive chemicals from coming into touch with the steel due to the zinc coating. It also has a scratch-resistant coating over the steel.
Screw Eye Bolts
Screw bolts are nothing more than a screw with an eye on it. A screw eye bolt, or a lag eye, has an eye on one end and a threaded shank that tapers to a point. You can screw them into wood or lag anchors and use them for light applications. In addition, there is no operating load restriction on them. Thus, it would be wise not to use them in overhead lifts or oversized loads.
Stainless Steel Eye Bolts
It retains its corrosion resistance when you scratch or beat up the stainless-steel . As a result, stainless steel greatly benefits rigging, tie-downs, and other demanding applications. Stainless steel comes in various grades, with 304 being the most prevalent. However, you can use the 316 grade in marine applications since it is resistant to salt and ocean spray.
Long Shank Eye Bolts
Long shank bolts come in various diameters and have a coating to prevent corrosion. In addition, these bolts commonly come in stainless steel and have a long lifespan. As a result, you can use them in a variety of applications.
