Please help us to share our service with your friends. 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. Please fill this form, xstm will try to respond as soon as possible.

I Washers Manufacture of D. Alloy steel eye bolts are forged, quenched, and tempered with improved toughness properties, intended primarily for low- temperature applications. Asttm Fasteners India Pvt. Material, Specification and Marking Eye bolts are made from forged carbon steel or alloy steel. 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.

Type 1, plain pattern straight shank ; Type 2, shoulder pattern; and Style B, short length. ASTM F requires the Eye Bolt Inspection Visually inspect each eye bolt before use. This specification covers two types denoting shank pattern, and one style denoting shank length, as follows: 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.

Thank you for interesting in our services.

When more than one eye bolt is used in conjunction with multiple-leg rigging, asmt bars or lifting beams should be used to eliminate angular loading.

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. Use two nuts if thickness is less than or equal to eye bolt diameter.

In qstm 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. Proper thread engagement must be maintained. 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.

Reeving will alter the angle of loading on the eye bolt as shown below. No other units of measurement are included in this standard. Please copy and paste this embed script to where you want to embed Embed Script.

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. 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. Only one leg should be attached to each eye bolt.

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.

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. 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.

This standard does not purport to address all of the safety concerns, if any, associated with its use. Link to Active This link will always route to the current Active version of the standard. This abstract is a brief summary of the referenced standard.

Eye bolts that are worn, cracked, bent, 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. We need your help to maintenance this website. The lifting eyes shall be manufactured as specified for the melting, forging, heat treatment, and machining processes.

ASTM A489 Specification

The astn properties to which the lifting eyes shall adhere are proof, breaking strength, tensile stress atsm strength, bend strength, impact strength, yield point, elongation, and reduction of area.

Eye bolts shall have a minimum design factor of 5, based on ultimate strength. 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. The lifting eyes shall be manufactured as specified for the melting, forging, heat treatment, and machining processes.

ASTM A – 18 Standard Specification for Carbon Steel Eyebolts

We need your help! 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. Installation for In-line Loading For in-line loading application use regular ashm eye bolt or shoulder nut eye bolt. Reeving of Sling Slings shall not be reeved through an eye bolt or reeved through a pair of eye bolts.

Never undercut eye bolt asrm seat shoulder against the load. Use number of nuts based on thickness of load as shown below.

Working Load Limit shown is for in-line pull. ASTM does not give any warranty express or implied or make any representation that the contents asstm this abstract are accurate, complete or up to date.

Always tighten nuts securely against the load. No other units of measurement are included in this standard. Sketches in this article are based on sketches in General Catalogue by Crosby Group.
