An eyebolt is a bolt with a loop at one end. The eyebolt has a threaded shank or rod which is securely screwed into a structure. Once the bolt is secured in place, ropes or cables can be anchored to or fed through the protruding loop (eye). Heavy-duty eye bolts can be used in rigging for lifting heavy loads, a smaller eyebolt can be used for tensioning wires, securing loads and other non-load bearing applications.
Shouldered Eye Bolts: Shouldered eye bolts are also referred to as “shoulder pattern” eye bolts. These eye bolts are designed with a shoulder at the point where the eye and the shank come together. This shoulder design reduces bending stress on the shank and allows the eye bolt to be used for angular lifting if the shoulder is properly seated in the load. If you are lifting with slings at ANY angle, you must use a shouldered eye bolt.
Non-Shouldered Eye Bolts: Non-shouldered eye bolts are also referred to as “plain pattern” eye bolts. Designed without a shoulder they can be used for truly vertical or in-line lifts. Non-shouldered eye bolts are not designed for any type of side loading or angular loading.
Forged Eye Bolts: Forged eye bolts are hammered or pressed into form which changes the grain structure of the metal to create a stronger and more durable product. Forged eye bolts are useful for heavy duty lifting applications as they are significantly stronger than wire eyes and can withstand loads up to the tensile strength of the material they are made from. They are available in larger sizes. When equipped with a shoulder, forged eye bolts can be used for in-line or angular loading.
Welded Eye Bolts: Welded Eye Bolts are ideal within light duty, non-lifting applications. Welded Eye Bolts are generally supplied with two washers and two nuts. Often these are made from Stainless Steel. This provides longevity in harsh environments or applications where rust should be avoided.
Bent Eye Bolts: Also referred to as turned eye or wire eye bolts these eye bolts are made from one-piece that is bent and shaped to form the eye. Bent eye bolts are used for lighter-duty applications and should not be used for heavy loads, which can cause the eye to open, or for angular loads, that can bend or break the bolt.
Nut Eye Bolts: The bottom of the shank protrudes through the bottom of the load and is secured in place with a nut. Nut eye bolts can be shouldered or non-shouldered and they can be fabricated through forged, welded, or bent eye methods.
Machinery Eye Bolts: The shank of these eyebolts is threaded and designed to be installed into tapped holes that have been engineered specifically as a lifting point.
Screw Eye Bolts: Screw eye bolts are just a screw with an eye. Also commonly referred to as lag eye, a screw eye bolt has an eye formed on one end and a threaded shank that tapers to a point. They are used for light applications and are screwed into wood or lag anchors. They don’t have a working load limit and are not recommended for use in overhead lifts or with heavy loads.
At Precision metal open or closed Eyes, Forged or Machined we offer all of these. We manufacture Eye Bolts as per Custom Specification across materials from stainless steel, carbon steel, Duplex and other exotics steels or any material composition as per custom specification.
Eyebolts can be supplied with many thread forms such as Left-Hand Threads, Right-Hand Threads, Metric Threads, Imperial Threads, ACME Threads. BSW, BSF, UNC, UNF are also available.
