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.
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.

Small screw eyes are used to hang picture frames and curtain wire. Ring bolt: An eyebolt with a captive ring passing through the eye of the head, effectively forming two chain links. This can reduce bending forces on an eyebolt.
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.
What is an eye bolt?
One of the most commonly used pieces of hardware in material handling, an eye bolt has a simple design, consisting of a threaded shank with a ring/eye at one end. Eye bolts are threaded to structures such as wood or steel posts and often supported by a nut.
Why are eye bolts available in different sizes?
As mentioned previously eye bolts are available in various sizes. The reason for this is to safely accommodate various loads/weights to be lifted.
How to find minimum depth of machinery eye bolt?
The minimum depth of the tap is obtained with the following formula: Minimum tap depth = basic shank length + half the nominal eyebolt diameter.
Why are stainless steel eye bolts so popular?
For this reason stainless steel eye bolts will endure longer in marine applications. Moreover, the smooth appearance makes this type of eye bolt suitable in architectural applications, and a popular choice in pharmaceutical and food processing industries, due to lack of peeling and flaking.
What is a standard lift on a bolt?
A standard lift applied through the shank of the eye bolt is when the load is pulled completely vertically or perpendicular to the shank of the eye bolt. This type of list is also referred to as a 0° lift.

Nor are the bolts designed to help pull a car out of mud or a ditch, a common misconception.
Do loading eye bolts work?
Nor are the bolts designed to help pull a car out of mud or a ditch, a common misconception. “Loading eye bolts have minimal strength for side force. They’re just designed to pull straight ahead, and only if the vehicle is still in an adequate condition to roll, i.e. still has 4 wheels/tires,” says Muzamel.
