Lifting Eye Bolt

ASTM A489 Type 1 Lifting Eye Bolts are forged, carbon steel threaded eye bolts intended for use with tapped holes that have been engineered as a lifting point. Dimensional specifications are governed by ASME B18.15 in sizes 1/4" through 2-1/2". According to ASME B30.26 - Rigging Hardware, each eye bolt shall be marked to show: 1. Name or trademark of manufacturer, 2. Size or rated load and 3. Grade for alloy eye bolts.

^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).
