Eye bolts according to this standard can be used in a temperature range from −20 ° C to +200 ° C without any restriction of the load capacity.
Domestic Forged Industrial Eye Bolts with a Shoulder Shank
Forged Eye Bolts - An eye bolt is a threaded rod with a ring for a head. In a shoulder pattern Eye Bolt, the ring is used to hold a fitting or a load, commonly seen in industrial applications. Shouldered eye bolts are eyebolts are used to secure an eye to a structure so that a rope, cable or other fixture may be attached to it.

What is an eyebolt?
An eyebolt is a mechanical fastener with a threaded shaft and a head forming a ring. Eyebolts are used to attach an eye to a structure, through which rope, cable or shackles can be secured. A common use is to create a lifting eye so that a crane can be attached to machinery, with special purpose lifting eyes rated for their safe working load.
What is pigtail eye bolt?
Pigtail eye bolts: These are a formed from a length of bar, similar to ordinary low strength eyebolts, but the head is bent into a helix so that it does not fully close on itself but can continue past 360 degrees. This allows the middle of a rope to be threaded into the eye without requiring access to an end.
What is shank in a shaft?
A shank is an unthreaded section of the shaft, below the shoulder , which provides a better transfer of load into the surface of the hole and is less likely to crack under a fatigue loading. Special types of eyebolt include: Anchor eyebolts: Eyebolts with some form of anchor bolt to enable fastening into masonry structures.
Why is it important to have an eyebolt on an off axis sling?
The ability to support off-axis loads is often important in lifting applications where lifting slings with multiple legs are used to attach to multiple lifting eyes. When lifting machinery, it is common for an eyebolt to be screwed directly into a tapped hole in the structure.
What is an anchor eyebolt?
Anchor eyebolts: Eyebolts with some form of anchor bolt to enable fastening into masonry structures. Screw eyes (or eye screws): The are similar to an eyebolt but with a wood screw in place of a machine screw. These are used for attaching an eye to wood or plastic structures.

Can an eyebolt be used for off axis loads?
The head is simply bent into a ring from an unthreaded section of the bar. These types of eyebolts can carry axial loads reasonably well but should not be used for off-axis loads. The opening where the end of the bar is closed to complete the ring may be welded but is likely to remain a possible point of failure.
