Use number of nuts based on thickness of load aetm shown below. Type 1, plain pattern straight shank ; Type 2, shoulder pattern; and Style B, short length. When eye bolts cannot be properly seated and aligned with each other, a steel washer or spacer not to exceed one thread pitch may be required to put below the eye bolt.

This standard specifies the basic dimensions, material, lifting capacity and conditions of use of lifting eyebolts of Grade M.

ASTM A489 Specification

Always countersink receiving hole or use washers to seat shoulder. One Response Jar Allah Says: 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.

Thank you for interesting in our services. 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. We are a non-profit group that run this website to share documents.

Never undercut eye bolt 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. Always tighten nuts securely against the load. 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.

ASTM A – 18 Standard Specification for Carbon Steel Eyebolts

Material, Specification and Marking Eye bolts are made from forged carbon steel or alloy steel. 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. For installation, tap the load tap depth to a minimum depth of one-half the eye bolt size beyond the shank length of the machinery eye bolt.

Superfast Fasteners Astk Pvt. For vertical loading, eye bolts without shoulders have the same load-carrying ability as shouldered eye bolts. Size px x x x x Eye bolts that are worn, cracked, bent, We need your help! If the eye bolt protrudes so far through the load that the aa489 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.

Only one leg should be attached to each eye bolt. Sketches in this article are based on sketches in General Catalogue by Crosby Group. Historical Version s – view previous versions of standard. This abstract is a brief summary of the referenced standard.

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.

For more information on eye bolts dimensions and swivel hoist rings different type of rings please refer General Catalog of the Crosby Group. ASTM F requires aetm No other units of measurement are included in this standard. This specification covers two types denoting shank pattern, and one style denoting shank length, as follows: No other units of measurement are included in this standard.

Installation for In-line Loading For in-line loading application use regular nut eye bolt or shoulder nut eye bolt.

Reeving will alter the angle of loading on the eye bolt as shown below. Working Load Limit shown is for in-line pull. 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.

Ensure that threads on shank and receiving hole are clean. Reeving of Sling Slings shall not be reeved zstm an eye bolt or reeved through a pair of eye bolts. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

If the hook does not go completely into the eye bolt, use a shackle to avoid loading astk hook tip. We need your help to maintenance this website. If the plane of the machinery eye bolt is not aligned with the sling line, add shims washers of proper thickness adtm adjust the angle of the plane of the eye to match the sling line as shown below.

The lifting eyes shall be manufactured as specified for the melting, forging, heat treatment, and machining processes.
