For vertical loading, eye bolts without shoulders have the same load-carrying ability as shouldered aatm bolts. 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. 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.

Eye Bolt Inspection Visually inspect each eye bolt before use. Link to Active This link will always route to the current Active version of the standard. Use two nuts if thickness is less than or equal to eye bolt diameter.

If the hook does not go completely into the eye bolt, use a shackle to avoid loading the hook tip. We need your help to maintenance this website.

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

If the eye bolt protrudes so far through the load that the nut cannot be aztm securely against the load, use properly sized a849 to take up the excess space between the nut and the load as shown below. Thank you for interesting in our services.

The mechanical properties to which the lifting eyes shall adhere are proof, breaking strength, tensile stress and strength, bend strength, asfm strength, yield point, elongation, and reduction of area. Use number of nuts based on thickness of load as shown below.

ASTM A489 Specification

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. Working Load Limit shown is for in-line pull. Only one leg should be attached to each eye bolt. Alloy steel eye bolts are forged, quenched, and tempered with improved toughness properties, intended primarily for low- temperature applications.

This abstract is a brief summary of the referenced standard. 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. Installation for In-line Loading Aetm in-line loading application use regular nut eye bolt or shoulder nut eye bolt.

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. When eye bolts cannot be properly seated and aligned with each other, a steel washer w489 spacer not to exceed one thread pitch a4889 be required to put below the eye bolt.

Reeving of Sling Slings shall not be reeved through an eye bolt or reeved through a pair of eye bolts. Superfast Fasteners Qstm Pvt.

ASTM A – 18 Standard Specification for Carbon Steel Eyebolts

We need your help! The lifting eyes shall be manufactured as specified for the melting, forging, heat treatment, and machining processes. 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. 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.

Always tighten nuts securely against the load. Size px x x x x Material, Specification and Marking Eye bolts are made from forged carbon steel or alloy steel.
