^AThe stress area is calculated as follows: As=0.7854 [D - (0.9743/n)]²
Where:
As = stress area, in.²,
D = nominal bolt size, and
n = threads per inch.
^BProof load is calculated as 2 times the rated capacity in straight pull (0 degrees) specified in ASME B18.15.
*NOTE: Rated capacity is for zero degree vertical pulls. Please Shoulder Eyebolt Rated Capacity/Guidelines for complete lifting information. Swivel Hoist Rings are recommended for angular lifts. Per ASME B18.15-1985 (R1995).

ASTM A489	Covers weldless forged, quenched, and tempered carbon steel threaded lifting eyes (formerly eyebolts) for overhead lifting.
ASME B18.15	Covers dimensions and capacities for carbon and stainless steel forged threaded eyebolts in sizes ¼ through 2-1/2 inch for steel and ¼ through 1-1/2” for corrosion resistant stainless steel intended primarily for lifting applications.
ASME B1.1 UNC Class 2A	Specifies the thread form, series, class, allowance, tolerance, and designation for unified screw threads.
