Top Questions And Answers For Eye Bolts

What Is An Eye Bolt Used For?

Eye bolts allow for the attachment and suspension of various structural elements. Their threaded end is installed into a structural material or the part to be suspended. Their looped end allows for the connection of other hardware, as well as chain, cable, rope, etc. Eye bolts facilitate lifting and hanging. They may be used temporarily for hoisting or may be used with permanent structural or decorative fixtures.

What Is A Shoulder Eye Bolt?

Shoulder eye bolts or shoulder pattern eye bolts can be identified by a rim or shoulder at the base of the eye. This feature is designed to facilitate even bearing on the installation, making them tough fastening solutions that are useful in many applications. Shoulder eye bolts can be attached with a nut as part of a fastener assembly or placed directly into the material using an anchor.

What Is A Lifting Eye Bolt?

Lifting eye bolts may be called lifting eyes or hoist rings, These components are used for vertical rigging and facilitate lifting at a 90-degree angle from the installation surface that remains in-line with the bolt. They facilitate single-point lifting or dual-point lifting with the incorporation of a spreader bar.

What Is A Bent Eye Bolt?

Bent eye bolts resemble a partially threaded rod with the unthreaded end bent back to create a loop or eye. This serves as a link point for cable, chain, turnbuckle, or other types of hardware, while the threaded end is embedded into the mounting material. These bolts represent one of the simpler types of eyebolts. They are more often used for lighter duty loads.

What does an eye bolt look like?

Eye bolts can be identified by a closed loop on one end, which allows cord, chain, or cable to be attached. This allows the piece to be hoisted or suspended. Eye bolts have a threaded shank or neck. This portion is installed into the material or paired with a nut to create a fastener assembly.

What Are Eye Bolts Made From?

Materials like carbon steel, alloy steel, stainless steel, and similar industrial-grade metals, are most frequently used in the manufacture of eye bolts. Coatings and finishes like hot-dipped galvanization can be applied to improve qualities such as corrosion resistance. Base material and treatments are a significant factor in whether a type of eye bolt is suitable for an application.

What Are Eye Bolt Applications?

Applications of eye bolts include posts made of wood, steel, and other structural materials. They are secured by a nut or can be installed into the material via an anchor, which is used when installing eye bolts into concrete. They allow for the attachment of cable, chain, or other hardware such as a turnbuckle. Eye bolts come in various types, the best choice of which will depend on the application.

How much weight can an eye bolt hold?

The working load limit or weight capacity of an eye bolt varies by factors that are integral to the bolt itself, such as its diameter, material, as well as its installation, and load angles. As the angle of suspension grows, the load limit of the eye bolt will decrease.

How is an eye bolt measured?

An eye bolt’s length is measured from the base of the loop to the tip of the threaded end. The diameter is consistent with other types of bolts. The dimensions of the loop are defined by the outer diameter of the eye and the inside diameter of the eye.

How Do You Screw In An Eye Bolt?

Eye bolts can be installed as a fastener assembly with a washer and nut. They are often tightened directly into the material but first, a pilot hole must be drilled to accommodate the length and diameter of the bolt. It can then be screwed in place manually or with a tool such as a screwdriver or pliers. The shaft of the bolt should be fully inserted up to the base of the loop.
