Machinery Eye Bolt Working Load Limits
Important:
The working load limits on this page apply only to machinery eye bolts and machinery eye bolts with shoulders. The working load limits for regular forged eye bolts can be found on our Forged Eye Bolt Working Load Limits page.
Working load limits for eye bolts are based on a straight vertical lift in a gradually increasing manner.
Load limits are based on a safety factor of 5 to 1.
Angular lifts will significantly lower working load limits and should be avoided whenever possible. If an angular lift is required, a properly seated shoulder pattern machinery eye bolt must be used.
Loads should always be applied to eye bolts in the plane of the eye, not at an angle to this plane. Angular lifts must never be more than a 45 degree pull.
