ASTM A489 Specification

ASTM A489 - Standard Specification for Carbon Steel Lifting Eye Bolts

This specification covers weldless forged, quenched and tempered carbon steel threaded lifting eyes or eyebolts for overhead lifting. ASTM A489 covers two types of lifting eye one denoting shank patter and other denoting shank length as defined in ANSI / ASME B18.15. Only imperial size eyebolts are available as per this specification with information mentioned in inch pound units. BoltPort can manufacture lifiting eye bolts as per ASTM A489 and supply with EN 10204 type 3.1 certification.

A The Stress area is calculated as follows: As = 0.7854[D-(0.9743/n)]2
Where As = Stress area, in2, D = Nominal bolt size, and n = Threads per inch. B Proof load is calculated as 2 times the rated capacity in straight pull (0 degrees) specified in ANSI/ASME B18.15.

ASTM A489 Grain Size Requirement

The finished lifting eye shall have an as-finished grain size of ASTM No. 5 or finer. The grain size shall be rated from a broken tensile specimen and representing a heat treated lot of one size.
