Ensure that threads on shank and receiving hole are clean. Please copy and paste this embed script to where you want to embed Embed Script. Always tighten nuts securely against the load. Never undercut eye atsm to seat shoulder against the load. Alloy steel eye bolts are forged, quenched, and tempered with improved toughness properties, intended primarily for low- temperature applications.

Reeving will alter the angle of loading on the eye bolt as shown below. 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.

ASTM A489 Specification

Proper thread engagement must be maintained. For more information on eye bolts dimensions and swivel hoist rings different type of rings please refer General Catalog of the Crosby Group. One Response Jar Allah Says: 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. The mechanical properties to which the lifting eyes shall adhere are proof, breaking strength, tensile stress and strength, bend strength, impact strength, yield point, elongation, and reduction of area.


Link to Active This link will always route to the current Active version of the standard. 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.

Thank you for interesting in our services. Use a washer with approximately the same diameter as the eye bolt shoulder and the smallest inside diameter that will fit the eye bolt shank. ASTM F requires the The mechanical properties to which the lifting eyes shall adhere are proof, breaking strength, tensile stress and strength, bend strength, impact strength, yield point, elongation, and reduction of area.

When eye bolts cannot be properly seated and aligned with each other, aa489 steel washer or spacer not to exceed one thread pitch may be required to put below the eye bolt. Therefore, in order to minimize the possibility of a brittle cleavage failure, these lifting eyes should never be loaded above the proof load, and should not be used when surface discontinuities exist on the awtm eyes.

Material, Specification and Marking Eye bolts are made from forged carbon steel or alloy steel.

ASTM A – 18 Standard Specification for Carbon Steel Eyebolts

We are a non-profit group that run this website to share documents. This specification covers two types denoting shank pattern, and one style denoting shank length, as follows: This standard specifies the basic dimensions, material, lifting capacity and conditions of use of lifting eyebolts of Grade M. The lifting eyes shall be manufactured as specified for the melting, forging, heat treatment, and machining processes.


No other units of measurement are included in this standard. Only one leg should be attached to each eye bolt. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine aatm applicability of regulatory limitations prior to use.

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. I Washers Manufacture of D.

ASTM A – 18e1 Standard Specification for Carbon Steel Eyebolts

Eye Bolt Inspection Visually inspect each eye bolt before use. 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.

Use two nuts if thickness is less than or equal to eye bolt diameter. If the plane of the machinery eye bolt is 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.

For vertical loading, eye bolts without shoulders have the same load-carrying ability as shouldered eye bolts. This abstract is a brief summary of the referenced standard. For installation, tap the load tap depth to a minimum depth of one-half the eye bolt size beyond the shank length of the 4a89 eye bolt.
