Eye Bolt Inspection Visually inspect each eye bolt before use. Therefore, in order to minimize the possibility of a brittle cleavage failure, these lifting astmm should never be loaded above the proof load, and should not be used when surface discontinuities exist on the lifting eyes.
Never undercut eye bolt to seat shoulder against the load.
Always tighten nuts securely against the load. For more information on eye bolts dimensions and swivel hoist rings different type of rings please refer General Catalog of the Crosby Group. The lifting eyes shall be manufactured as specified for the melting, forging, heat treatment, and machining processes.
No other units of measurement are included in this standard. If the hook does not go completely into the eye bolt, use a shackle to avoid loading the hook tip.
ASTM A489 Specification
ASTM F requires the 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: Historical Version s – a498 previous versions of standard. 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. For installation, tap the load tap depth to a minimum depth of one-half the eye bolt size beyond the shank length of asmt machinery eye bolt.
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 asgm the eye to match the sling line as shown below.

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 astn steel threaded lifting eyes formerly pertained to as eyebolts for overhead lifting. Only one leg should be attached to each eye bolt. Eye bolts that are worn, cracked, bent, September 18th, at Reeving will alter the angle of loading on the eye bolt as shown below.
We need your help! 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. Thank you for interesting in our services. 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.
Use number of nuts based on thickness of load as shown below. 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. We need your help to maintenance a48 website.
