Closed Eye Bolt

A: The load rating of an eye bolt (lifting eye) is considerably dependent upon its size, material, angle of loading and degree fo swiveling. There is no single answer.

For the frequently used smaller diameters such as M8, M10, and M12, prescribed vertical load capacities are in practice something like 140 kg, 230 kg or preferably 340 kg using the according standards (like DIN 580). Some of the larger industrial rotating eye bolt sizes in these include ones that can safely handle.25 tons,.4 tons and.65 tons.

Ergo M16, M20 and M24 are heavier duty alternatives with standard vertical capacities of around 510 kg, 847 kg and 1.3 tonne respectively. High-Performance Forged Swivel Hoist Ring These diameters in high-performance forged swivel hoist rings can have much greater capacities, for instance about 1.12 tons, 2 tons and even 3.15 tons.

A: Function & Use:

Eye bolt :Used for static lifting. As a permanent or temporary lifting point for lifting equipment.

Ring eye bolt: For hinged/articulating connections. It connects things that have to move or be repositioned.

Core Structure:

Eye Bolt: Features a solid forged eye for plain or arched shackles and hooks.

Ring Bolt: With pivoted ring and pin which can be rotated freely.

Load & Safety:

Eye Bolt (Carry the full load) And it needs too much vertical correction, and the requirement of safety is very high.

Ring bolt: Primarily used for shear and dynamic loads, usually higher working load than other types.
