This specification covers two types denoting shank pattern, and one style denoting shank length, as follows: We need your help!

Link to Active This link will always route to the current Active version of the standard. This standard covers only eyebolts with eyes of internal diameters capable of permitting direct engagement astn eyehooks of the same lifting capacity working load limit for use with Grade T 8 chain. Reeving of Sling Slings shall not be reeved through an eye bolt or reeved through a pair of eye bolts. Please fill this form, we will try to respond as soon as possible.

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. We need your help to maintenance this website.

ASTM A – 18e1 Standard Specification for Carbon Steel Eyebolts

No other units of measurement are included in this standard. Always tighten nuts securely against the load. 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. Type 1, plain pattern straight shank ; Type 2, shoulder pattern; and Style B, short length.


One Response Jar Allah Says: Historical Version s – view previous versions of standard. Eye bolts that are worn, cracked, bent, It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

ASTM A – 12 Standard Specification for Carbon Steel Lifting Eyes This specification covers the chemical, mechanical, grain size, and dimensional requirements for weldless forged, quenched, and tempered carbon steel threaded lifting eyes formerly pertained to as eyebolts for overhead lifting.

This standard specifies the basic dimensions, material, lifting capacity and conditions of use of lifting eyebolts of Grade M. We are a non-profit group that run this website x489 share documents. ASTM F requires the Ensure that threads on shank and receiving hole are clean.

ASTM A489 Specification

Please copy and paste this embed script to where you want to embed Embed Script. If the hook does not go completely into the eye bolt, use a shackle to avoid loading the hook tip. This standard does not purport to address all of the safety concerns, if any, associated with its use. Alloy steel eye bolts are forged, quenched, and tempered with improved toughness properties, intended primarily for low- temperature applications. Use one nut if thickness is more than one eye bolt diameter.

Only one leg should be attached to each eye bolt.

Type 1, plain pattern straight shank ; Type 2, shoulder pattern; and Style B, short length. This specification covers two types denoting shank pattern, a49 one aztm denoting shank length, as follows: This abstract is a brief summary of the referenced standard. No other units of measurement are included in this standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.


September 18th, at Working Load Limit shown is for in-line pull. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Proper thread engagement must be maintained. If the eye bolt protrudes so far through the load that the nut cannot ast tightened securely against the load, use properly sized x489 to take up aa489 excess space between the nut and the load as shown below.

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. 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 lifting eyes.

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.
