ASTM A489-12

1.1 This specification covers weldless forged, quenched, and tempered carbon steel threaded lifting eyes (formerly eyebolts) for overhead lifting.

Note 1—Lifting eyes carrying this specification number even though they are liquid quenched and tempered may be processed from carbon steel which, in the composition range permitted by this specification, could have a fracture appearance transition temperature (50 % shear) higher than operating temperatures. 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.

1.2 The specification includes two types denoting shank pattern and one style denoting shank length (both defined in ASME B 18.15) as follows:

1.2.1 Type 1—Plain pattern (straight shank).

1.2.2 Type 2—Shoulder pattern.

1.2.3 Style B—Short length.

1.3 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.

1.4 Terms used in this specification are defined in Terminology F1789 unless otherwise defined herein.

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 specification covers two types denoting shank pattern, and one style denoting shank length, as follows: Type 1, plain pattern (straight shank); Type 2, shoulder pattern; and Style B, short length. The lifting eyes shall be manufactured as specified for the melting, forging, heat treatment, and machining processes. 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.
