Collar eyebolt dims

Collared eyebolts are used when lifting on two or more points using a chain sling for example. When making your selection it is important that you remember that a reduction in the Safe Working Load must be factored in to take account of the slinging angle. The Collared eyebolt has a relatively small eye diameter and is usually specified with shackles.

Reduction Factors

When using Collared eyebolts at an inclined angle a reduction factor must be used to ensure that the eyebolts are not overloaded.
