Questions And Answers On Eye Bolts

What Are Eye Bolts Made From?

Carbon steel, alloy steel, stainless steel, and other industrial-quality metals are among the most common materials used to make eye bolts.

They can also be treated with resistance-boosting finishes like hot-dipped galvanization in the same manner as other construction bolts. The materials and treatments of the eye bolt can be a considerable factor in how it will perform in an application.

What Is A Shoulder Eye Bolt?

Shoulder eye bolts, sometimes called shoulder pattern eye bolts, are similar to regular eye bolts but they feature a rim or shoulder. This improves bearing and better secures the bolt to the installation surface.

Shoulder eye bolts are tough fasteners that can be used in varied industrial settings. They may be installed into the material or secured with a nut as a fastener assembly.

What Is A Lifting Eye Bolt?

Lifting eye bolts are used in rigging when hoisting must be done at a 90-degree angle from the installation surface in a way that remains in-line with the bolt.

They can be used for single or dual-point lifting, provided a spreader bar is used when two points are required. These fasteners are sometimes referred to as lifting eyes or hoist rings.

What Is A Bent Eye Bolt?

A bent eye bolt is formed from a partially threaded rod. The unthreaded end is bent around, which creates the loop or eye of the bolt.

The eye serves as a connection point for chain, cable, turnbuckles, or similar hardware. The threaded end is tightened into the mounting material.

Bent eye bolts are one of the simpler types of eyebolts. They are best suited for lighter duty loads.

What Does An Eye Bolt Look Like?

An eye bolt’s most notable feature is the closed loop end. This portion is meant to hold cord, chain, or cable, which is attached with other hardware.

Various fixtures and structural elements can be hoisted or suspended from this connection point. The opposite end has a threaded shank or neck, which is installed into the material or attached with a nut.

What Is An Eye Bolt Used For?

Eye bolts are used to hang and hoist various structural elements. They are also installed into structures to permit the suspension of fixtures, furnishings, and parts.

Hardware, cable, or chain can be attached to the looped end of the bolt, while the threaded end is installed into a wall, beam, ceiling, or other part.

They may be installed temporarily for lifting purposes or may be a permanent fastener.

What Are Eye Bolt Applications?

Eye bolt applications include wood and steel posts and various rigging equipment. They are sometimes secured with a nut or can be embedded into a material such as concrete with an anchor.

They facilitate cable and chain connections or the attachment of other hardware such as a turnbuckle. The specific type of eye bolt will be a factor in whether or not it is a suitable application.

How Much Weight Can An Eye Bolt Hold?

The weight capacity or working load limit of an eye bolt will vary based on a number of factors, including the material from which it is made, the diameter of the shank how it is installed, and the angle of the load.

Weight capacity or working load limit of an eye bolt will decrease as the degree of the suspension angle increases.

How Is An Eye Bolt Measured?

Eye bolt measurements are based on its length and diameter. The length is taken from the base of the loop, starting from the point that will sit flush within the material, to the end of the threads.

These dimensions are consistent with other types of bolts, except for the head. As eye bolts have a loop, the inner and outer diameters of the loop must be accounted for.

How Do You Screw In An Eye Bolt?

Eye bolts are installed with a washer and nut or directly into the material or workpiece. Once a pilot hole is drilled, the eye bolt can be screwed in place by hand, using manual tools, or heavy-duty construction equipment.

The eye bolt should be tightened so that the base of the loop sits flush with the material surface.
