How To Choose And Use The Right Eye Bolts For Your Application

Eyebolts are among the most common sorts of rigging gear, and they’re used as a hoisting or outstanding security point. Like a sling, hook bolts, and chain, they exist in various forms and arrangements. Lifting, attaching, tugging, pushing, and lifting operations can all benefit from them.

An eyebolt is widely utilised for industrial purposes, but they’re also frequently misinterpreted or misused. It might be challenging to know the kind of eye bolt to operate with your other hoisting equipment for your specific purpose.

What Exactly Are Eye Bolts?

An eyebolt is essential hardware consisting of a slotted shaft with a circle at one head. It is threaded into wooden or metal frames and is typically provided by a nut. To hoist items, they are intended to have a string or wire fed through all the circles. The circle could be dip cast (inside one block with the eye completely sealed) or twisted into a loop. Just utilise twisted eye bolts in gentle situations or never use them to conduct angular lifts.

There are two types of eyebolt, including rated and unrated eyebolts. Rated eye bolt has been professionally lab validated for efficiency and material property compliance with regulating standards. At the same time, an unrated eyebolt is a device that has not been evaluated to guarantee conformity with any governmental regulations, as the name indicates. These eyebolts are often less costly and are best used in situations with modest loads.

What Are The Materials For Eye Bolts?

Steel, carbon, and alloy steel are among the most prevalent materials used in eye bolts. Owing to the steel structure, which comprises iron, chromite, magnesium, silica, nickel, and trace quantities of carbon, metal eye bolts are almost rust-proof.

As a result, metal eye bolts in maritime situations will last longer. Furthermore, given the absence of flaking and cracking, this eyebolt is appropriate for construction purposes and is a standard option in the food and pharmaceutical processing sectors.

How Do You Choose The Correct Bolt?

Please use the eye bolt with the maximum weight imprinted on it. The needle size of an eye hook bolt is not the same as the stated capacity. Ensure you get the right eyebolt for the job, depending on the kind and capability of the lift.

  • Regarding vertical loads application, use a standard or direct eye bolt (non-shoulder) or a hook bolt. Angle pressure will deform or fracture non-shouldered bolts.
  • Regarding vertical or angle loads, apply shoulder eye bolt. Keep in mind that elevating eye bolts at such an elevation limits the amount you may safely carry.
  • When it comes to angle mounting, stick to the manufacturer’s guidelines.
  • Choose an eye bolt made from materials that can endure any conditions in which it will be utilised.

What Are The Safest Ways To Utilise Eye Bolts?

It’s just as vital to choose the right eye bolt as it would be to use and maintain it correctly. Here are some ways of utilising an eyebolt safely.

  • Each eyebolt should be aligned with the slings. It can bend if the force is applied laterally.
  • To guarantee that the eye bolt securely touches the force area, spacers should be placed between both the shoulder and the force area. Ensure that the screw is tensioned appropriately.
  • When employing shims or washers, be sure that at least 90% of the screws in the reception holes are engaged.
  • Just one holster leg should be attached to every eye bolt.
  • Examine and polish the screws of the eye bolt and the hole. Examine the screws for any bends, splits, or wear.
  • Install the eye bolt completely downward and ensure that it is positioned correctly.
  • Keep in mind that the threaded hole for a tightened eye bolt (central bolt) is at least one and one-half duration the size of the bolt.
  • Attach the shoulder at such an elevation to the belt’s centre. The shoulder must be in complete touch with the lifting image.
  • Apply a spreading bar with an ordinary eye bolt to maintain the elevation angle at 90 degrees to the ground.
  • It would help if you used an eye bolt at a particular angle higher than 45 degrees. At 45 degrees, slinging strength is 71% of vertically slinging capability. At a 45° horizontal plane, eye bolt power declines to 30% vertical lifting ability.
  • For slanted raises, use a rotating hoisting ring. The rotating hoisting ring rotates an all-around bolt to accommodate any slinging position, and the elevating eye swivels 180 degrees.


Eye bolts can provide extra functionality based on the material structure and polish – a few are appropriate for low-temperature activities. In contrast, others are meant not to reflect sunlight and fade into the backdrop. Furthermore, it is vital to determine the force transmitted to the eye bolt in choosing an eye bolt. If you’re not sure how much weight you’ll be carrying, go with a bigger eye bolt to be secure.
