Introduction
In industrial and construction projects, safety and strength are essential. The EYE Bolt is a small but powerful fastener that ensures reliable lifting, anchoring, and securing of heavy loads. Designed with a circular or “eye-shaped” head, the Lifting bolt allows for easy attachment of ropes, cables, or hooks, making it a must-have component in lifting and rigging systems.
At AN Fastener Supplier, we manufacture high-quality Lifting bolts that meet strict international standards. Whether used for machinery lifting, structural anchoring, or marine applications, our Lifting bolt provides the stability, durability, and precision your projects demand.
The Lifting bolt combines engineering strength with simplicity — its robust design ensures long-term reliability under heavy stress and harsh conditions.
What is an EYE Bolt?
An EYE Bolt is a mechanical fastener with a threaded shank and a looped head resembling an eye. It is designed to be screwed into a structure or piece of equipment to create a secure attachment point. The Lifting bolt allows chains, ropes, or cables to pass through the loop, making it suitable for lifting, pulling, and securing heavy loads.
The EYE Bolt is typically made from durable metals such as stainless steel, mild steel, or galvanized steel to withstand mechanical stress and environmental exposure. With its strength and reliability, the Lifting bolt is an indispensable part of industries like construction, shipping, machinery, and mining.
Key Features of an EYE Bolt
The EYE Bolt stands out because of its special design and versatile properties. Here are its key features:
- High Tensile Strength: The EYE Bolt can handle substantial loads without deformation.
- Corrosion Resistance: Stainless steel or galvanized finishes protect the Lifting bolt from rust.
- Thread Accuracy: Precision threading ensures secure fitting and easy installation.
- Multiple Head Designs: The Lifting bolt comes in various types, including plain, shoulder, and machinery designs.
- Ease of Use: Simple structure allows quick and secure connections.
- Durability: A high-quality Lifting bolt lasts for years, even in harsh environments.
Each Lifting bolt produced by AN Fastener Supplier undergoes quality testing to ensure maximum strength and safety.
Types of EYE Bolts
Different applications require different Lifting bolt designs. Here are the most common types available at AN Fastener Supplier:
- Plain Pattern EYE Bolt – Used for vertical loading applications where no angular tension is applied.
- Shoulder Pattern EYE Bolt – Has a shoulder that allows angular loading up to 45°, ideal for lifting at an angle.
- Machinery Lifting bolt – Precision-forged and threaded for heavy-duty machinery and equipment lifting.
- Swivel Lifting bolt – Designed to rotate under load to prevent twisting of lifting cables.
- Lag EYE Bolt – Comes with a wood screw thread, used in wood and light applications.
- Collared EYE Bolt – Equipped with a reinforced collar for maximum load capacity.
- Custom Lifting bolt – Manufactured to specific size, material, and design requirements.
Each Lifting bolt type is tested for load-bearing strength and safety performance.
Applications of EYE Bolts
The EYE Bolt is used in a wide range of industries and projects due to its versatility and load-bearing capabilities. Common applications include:
- Construction: For lifting and securing structural steel and concrete elements.
- Marine: Stainless steel Lifting bolt resist corrosion in saltwater environments.
- Machinery: Used for lifting motors, pumps, and heavy equipment safely.
- Aerospace: Used in lightweight but high-strength load applications.
Wherever heavy or dynamic loads are present, the Lifting bolt offers reliable performance.
Manufacturing Process of EYE Bolts
At AN Fastener Supplier, every Lifting bolt is manufactured using advanced technology and strict quality control measures. Here’s a step-by-step overview of how we produce durable EYE Bolts:
- Material Selection: Only high-grade steel is selected for consistent strength and ductility.
- Cutting: Rods are cut to the required lengths with precision cutting machines.
- Forging: The looped “eye” is formed using hot forging to ensure a strong, uniform structure.
- Thread Rolling: Threads are rolled (not cut) for better fatigue strength and load capacity.
- Heat Treatment: Enhances toughness and mechanical strength.
- Surface Finishing: Galvanizing or coating provides corrosion resistance and a clean surface.
- Inspection: Each Lifting bolt is checked for tensile strength, hardness, and dimensional accuracy.
This process ensures every EYE Bolt meets high safety standards and international norms.
