An eye bolt is a bolt with a loop at one end. They are used to firmly attached a securing eye to a structure, so that ropes or cables may then be tied to it. Machinery eye bolts are fully threaded and may have a collar, making them suitable. for use with angular loads up to 45°. eye bolts without a shoulder should not be used for angular loads.The eye bolt is different with ring bolts. It has a single ring forged to the top of the shank, while the ring bolt has an additional ring that articulates around this first forged ring. This means that the eye bolt is designed to accommodate forces from straight above or below, while the ring bolt can handle forces coming from an angle.

▲Shouldered Eye Bolts vs. Non-Shouldered Eye Bolts When selecting the proper eye bolt for your application, one of the most important considerations is whether you need a shouldered or non-shouldered (plain pattern) eye bolt. A shouldered eye bolt can be used for vertical in-line lifts or for angular lifts. Non-shouldered eye bolts should be used for in-line or vertical lifts only and should NEVER be used for angular lifts. ▲Shouldered Eye Bolts Shouldered eye bolts are also commonly 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 stresses on the shank and allows the eye bolt to be used for angular lifting if the shoulder is properly seated in the load. When used for side loading or angular loading, you must ensure that the shoulder is completely flush to function properly. Always follow the manufacturer’s specifications and reduction in capacity based on the different angle of loading. 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 commonly referred to as “plain pattern” eye bolts. Designed without a shoulder, they can only be used for truly vertical or in-line lifts. Non-shouldered eye bolts are not designed for, or intended to be used for, any type of side loading or angular loading.
