Eye Bolt
An eye bolt is a fastener with a ring-shaped element ("eye") on one end and a threaded rod on the other, commonly used for lifting operations and rigging connections.
Structural Features
The eye bolt consists of a threaded rod and an integrally forged ring. The ringed part is designed to connect to cables, chains, or other linking components, while the threaded part can be secured with a nut or screwed into threaded holes for reliable fixation.
Types
1. Bent Eye Bolts: Typically made from bent metal rods, suitable for light loads (e.g., securing tents, tarps), and cost-effective.
2. Standard Eye Bolts: No additional reinforcements, designed for vertical lifting (load aligned with the rod axis), widely used in shipbuilding and construction.
3. Shoulder Eye Bolts: Feature a reinforced flange, withstand angular loads, distribute force evenly, and reduce deformation risk. Used in heavy-duty rigging systems.
Materials
• Steel: Provides high strength and cost-effectiveness for general applications.
• Stainless Steel (Grades 304 and 316): Offers enhanced corrosion resistance, suitable for humid and chemically aggressive environments.
• Galvanized Steel: Zinc coating improves anti-corrosion properties, recommended for outdoor use.
Primary Functions
Eye bolts provide secure anchoring points for connecting cables, chains, and structural components. They are used for lifting, securing, or pulling operations: in construction for material hoisting, in machinery for equipment component fixation.
Precautions
When using eye bolts, ensure:
1. Select the type based on actual load requirements.
2. Verify the rated load capacity meets operational demands.
3. Install correctly with full tightening to prevent accidents.
4. For angular loads, use only shoulder eye bolts and adhere to specified installation angles.
