Eye Bolts
Eye Bolts are specialized fasteners featuring a looped or circular head, designed for lifting, rigging, securing loads, and anchoring applications. These bolts offer exceptional tensile strength, load distribution, and safety, making them ideal for construction, industrial lifting, marine, and heavy machinery applications.
At Rajal Industries, we manufacture precision engineered Eye Bolts that conform to ISO, ASME, and DIN standards, ensuring high load-bearing capacity, corrosion resistance, and durability in demanding environments.

- DIN 580 Grade 8.8 Lifting Eye Bolt : 12,500 N (M10)
- ISO 6474 Stainless Steel Eye Bolt : 10,000 N (M8)
- ASME B18.12 Forged Eye Bolt : 20,000 N (1/2")
Head & Eye Design Specifications
Looped or Circular Head for Secure Load Attachment
- The eyelet allows secure fastening of cables, hooks, and chains, ensuring safe lifting and anchoring.
- Designed to handle static and dynamic loads, preventing deformation or failure under stress.
Threaded & Unthreaded Variants for Versatile Use
- Fully Threaded Eye Bolts – Provide secure engagement with nuts and mating surfaces.
- Shoulder Eye Bolts – Designed for angled lifts and high-load applications.
- Collar Eye Bolts – Offer reinforced grip strength in heavy lifting operations.
Precision-Machined Threading for Load Transfer
- Threads conform to ISO metric and UNC/UNF standards, ensuring high-strength connections in industrial use.
- Available in coarse and fine thread profiles for better load distribution and reliability
Thread Specifications & Precision Engineering
| Thread Type | Description | Application |
|---|---|---|
| Coarse Thread (UNC/ISO Metric) | Provides high durability and easy installation | General lifting, anchoring, rigging |
| Fine Thread (UNF/Metric Fine) | Offers higher tensile strength & load control | Precision lifting, seismic applications |
| Fully Threaded Eye Bolts | Allows maximum engagement with nuts | Adjustable load-bearing connections |
| Partially Threaded Eye Bolts | Provides higher shear strength & rotational stability | Machinery lifting, industrial mounting |
Thread Fitment & Compliance
- Metric threads conform to ISO 6g tolerances, ensuring secure and stable lifting.
- Imperial threads comply with ASME B18.12 and DIN 580 for high-load performance.
Corrosion Resistance & Environmental Suitability
Eye Bolts are used in marine, industrial, and outdoor environments, requiring protective coatings for longevity.
| Coating Type | Corrosion Protection Level | Ideal Applications |
|---|---|---|
| Plain Steel (No Coating) | Low | Indoor applications |
| Zinc Plated (Yellow/Blue/White/Black) | Moderate (48-96 hours SST) | General lifting, light-duty rigging |
| Hot-Dip Galvanized (HDG) | High (600+ hours SST) | Outdoor, heavy industrial use |
| Electropolished Stainless Steel | Extreme (1000+ hours SST) | Marine, aerospace, high-humidity environments |
Salt Spray Testing (SST) per ASTM B117 & ISO 3266 ensures long-term rust prevention and surface protection.
Common Applications of Eye Bolts
- Lifting & Rigging Equipment – Used in hoists, cranes, and pulleys for secure lifting
- Marine & Offshore Engineering – Essential for shipbuilding, oil rigs, and dockyard applications.
- Construction & Structural Anchoring – Used in scaffolding, safety harnesses, and framework assembly.
- Industrial Machinery & Heavy Equipment – Provides secure attachment points for transportation and lifting.
- Renewable Energy & Aerospace – Used in wind turbines, aircraft maintenance, and solar panel installations.
