We need your help to maintenance this website. 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.
ASTM A489 Specification
Installation for In-line Loading For in-line loading application use regular nut eye bolt or shoulder nut eye bolt. Superfast Fasteners India Pvt. I Washers Manufacture of D. Use one nut if thickness is more than one eye bolt diameter. 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.
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. Ensure that threads on shank and receiving hole are clean. This standard specifies the basic dimensions, material, lifting capacity and conditions of use of lifting eyebolts of Grade M.
Application It is recommended axtm use shouldered eye bolts for rigging hardware, except when prohibited by the ast, of the item to which the eye bolt is attached. This specification covers two types denoting shank pattern, and one style denoting shank length, as follows: 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.
This standard does not purport to address all of the safety concerns, if any, associated with its use.
Proper thread engagement must be maintained. Thank you for interesting in our services.
a4489 Always countersink receiving hole or use washers to seat shoulder. Historical Version s – view previous versions of standard. Link to Active This link will always route to the current Active version of the standard. 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. When eye bolts cannot asmt 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.
For vertical loading, eye bolts without shoulders have the same load-carrying ability as shouldered eye bolts. The lifting eyes shall be manufactured as specified for the melting, forging, heat treatment, and machining processes. ASTM F requires the 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.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. We are a non-profit group that run this website to share documents. 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. This specification covers the chemical, q489, grain size, and dimensional requirements for weldless forged, quenched, and tempered carbon steel threaded lifting eyes formerly pertained to as eyebolts for overhead lifting.
Reeving of Sling Slings shall not be reeved through an eye bolt or reeved through a pair of eye bolts. 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.
For more information on eye bolts dimensions and swivel hoist rings different type of rings please refer General Catalog of the Crosby Group. Please help us to share our service with your friends. Reeving will alter the angle of loading on the eye bolt as shown below.
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. Material, Specification and Marking Eye bolts are made from forged carbon steel or alloy steel. Type 1, plain pattern straight shank ; Type 2, shoulder pattern; and Style B, short length.
