Lifting eyes, also commonly known as eye bolts, have widespread use in industrial plants. They are commonly used on dies, cabinets, compressors, 

Here are some terms you should familiarize yourself with to help you understand the different types and design of lifting eye bolts: Eye - loop formed at the top that can be either bent, welded, or forged Shoulder - "skirt" where the eye and shank come together designed to resist bending Shank - threaded shaft that attaches to the eye

Shoulder Eye Bolts Never Exceed Working Load Limits. Never use regular nut eye bolts for angular lifts. Always use shoulder nut eye bolts for angular lifts.

391 products. Eye bolts have a shank for anchoring to structures or equipment and a ring (or loop) at the top for attaching rope, hooks, or other hardware. They're used as anchor eye bolts for routing or tying down wire and cable. Machinery or lifting eye bolts are rated for vertical or angular lifting up to their specified capacity. Application.

Bolts can fail by due to several reasons including (1) the bolt had not been sufficiently preloaded/tension during installation, (2) had lost its preload during service, (3) the applied cyclic loading had been excessive – far beyond the strength of the bolt and/or (4) the bolt had been understrength (quality issue/wrong grade).

Internally Threaded Rod End Bolts with Partial Threads. Also known as swing bolts and eyebolts, these internally threaded rod end bolts have no moving parts. They're designed to make pivoting or hinge movements in applications that don't need to compensate for misalignment.

The bolts which are used with collars are suitable even for angular loads whereas those which do not have a shoulder are not suitable for angular loads. However, for heavy off-axis loads, an eye bolt with continuous eye and integral shoulder can be used. Be sure to restrict the axis angle to less than 45 degrees.

Eyebolts, one of the most commonly used items of lifting gear, have severe limitations in usage and a high level of accidents occur as the result of misuse. Eyebolts are used in a wide variety of applications to provide lifting points on loads. Sometimes the hole they are screwed into is there specifically for the eyebolt.

An eyebolt can be used to attach an eye to a structure with something like a cable or rope. You can also use a lifting eye so a crane can 

Failure to do so may allow the coil rod to bend and precipitate a premature failure. WARNING: Eye Bolts are intended for straight tension loading only. Angular loading severely reduces the safe workloads and must be avoided or properly considered. See reduction factors below. Performance Data Print Product Email Product Inquire About this Product
