ASTM A – 00 Standard Specification for Carbon Steel Lifting Eyes

Please help us to share our service with your friends. Material, Specification and Marking Eye bolts are made from forged carbon steel or alloy steel. Alloy steel eye bolts are qstm, quenched, and tempered with improved toughness properties, intended primarily for low- temperature applications. Eye bolts shall have a minimum design factor of 5, based on ultimate strength.

Working Load Limit shown is for in-line pull. ASTM F requires the This standard specifies the basic dimensions, material, lifting capacity and conditions of use of lifting eyebolts of Grade M.

This standard covers only eyebolts with eyes of internal diameters capable of permitting direct engagement with eyehooks of the same lifting capacity working load limit for use with Grade T 8 chain.

In the case of eyehooks for use with Grade M 4 chain, it may be necessary to use an intermediate component such as a shackle to make the connection. Application It is recommended to use shouldered eye bolts for rigging hardware, except when prohibited by the configuration of the item to which the eye bolt is attached. Where non-shouldered eye bolts are required, they shall be used only in vertical pulls or in rigging systems that are designed, analyzed, and approved by a qualified person.


For vertical loading, eye bolts without shoulders have the same load-carrying ability as shouldered eye bolts. Never undercut eye bolt to seat shoulder against the load. Always s489 receiving hole or use washers to seat shoulder.

Atsm more a498 one eye bolt is used in conjunction with multiple-leg rigging, spreader bars or lifting beams should be used to eliminate angular loading. In case two or more than two eye bolts are used without spreader bars, their orientation shall be such that load is in the plane of the eyes as shown below Orientation of eye bolts. When eye bolts cannot be properly seated and aligned with each other, a steel washer or spacer not to exceed one thread pitch may astj required to put below the eye bolt.

Proper thread engagement must be maintained. Use a washer with approximately the same diameter as the eye bolt shoulder and the smallest inside diameter that will fit the eye bolt a4899. If the hook does not go completely into the eye bolt, use a shackle to avoid loading the hook tip.

Installation for In-line Loading For in-line loading application use regular nut eye bolt or shoulder nut eye bolt. Use number of nuts astj on thickness of load as shown below.

Use one nut if thickness is more than one eye bolt diameter. Use two nuts if thickness is less than or equal to eye bolt diameter. Always tighten nuts securely against the load. If the eye bolt protrudes so far through the load that the nut cannot be tightened securely against the load, use properly sized washers to take up the excess space between the nut and the load as shown below. Reeving of Sling Slings shall not be reeved through an eye bolt or reeved through a pair asym eye bolts.


Reeving will alter the angle of loading on the eye bolt as shown below. Only one leg ast be attached to each eye bolt.

ASTM A489 Specification

For installation, tap the load tap depth to w489 minimum depth of one-half the eye bolt size beyond the shank length of the machinery eye bolt. If the plane of the machinery eye bolt a49 not aligned with the sling line, add shims washers of proper thickness to adjust the angle of the plane of the eye to match the sling line as shown below.

Eye Bolt Inspection Visually inspect each eye bolt before use. Eye bolts that are worn, cracked, bent, Ensure that threads on shank and receiving hole are clean.
