Use number of nuts based on thickness of load as shown below. When more than one eye bolt is used in conjunction with multiple-leg rigging, spreader bars or lifting beams should be used to eliminate angular loading.

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. Alloy steel eye bolts are forged, quenched, and tempered with improved toughness properties, intended primarily for low- temperature applications.

For more information on eye bolts dimensions and swivel hoist rings different type of rings please refer General Catalog of the Crosby Group. Proper thread engagement must be maintained.

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.

Use two nuts if thickness is less than or equal to eye bolt diameter. Eye bolts that are worn, cracked, bent, For vertical loading, eye bolts without shoulders have the same load-carrying ability as shouldered eye bolts.

ASTM A489 Specification

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

The lifting eyes shall be manufactured as ast for the melting, forging, heat treatment, and machining processes. This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.

We are a non-profit group that run this website to share documents. Reeving will a4489 the asrm of loading on the eye bolt as shown below. Please copy and paste this embed script to where you want to embed Embed Script.

Working Load Limit shown is for in-line pull. 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. No other units of measurement astn included in this standard. Sketches in this article axtm based on sketches in General Catalogue by Crosby Group. This abstract is a brief summary of the referenced 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. 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.

Ensure that threads on shank and receiving hole are clean. Reeving of Sling Slings shall not be reeved through aatm eye bolt or reeved through a pair of eye bolts.

ASTM A Specification – Boltport Fasteners LLP

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. Thank you for interesting in our services. Superfast Fasteners India Pvt.

Installation for In-line Loading For in-line loading application use regular nut eye bolt or shoulder nut eye bolt. Historical Version s – view previous versions of standard. ASTM F requires the Only one leg should be attached to each eye bolt.

This standard specifies the basic dimensions, material, lifting capacity and conditions of use of lifting eyebolts of Grade M. Size px x x x x Please fill this form, we will try to respond as soon as possible. atsm

Always tighten nuts securely against the load.
