Stud link anchor chains are essential components in the marine and offshore industries, providing reliable anchoring and mooring solutions for vessels, oil rigs, and floating equipment. These chains feature a central stud in each link, enhancing strength, durability, and resistance to deformation under heavy loads. As a modern factory specializing in the production and installation of marine anchor chains, buoy anchor chains, and outfitting products, we offer OEM services to international brands, wholesalers, and manufacturers. This article explores the top stud link anchor chain manufacturers and suppliers in America, highlighting their capabilities, products, and industry standards.
A stud link anchor chain is a type of chain distinguished by a cross-piece, or stud, inside each link. This stud prevents the link from deforming and reduces twisting or kinking during deployment and retrieval, making it ideal for maritime use. Typically made from high-grade steel such as hot-rolled anchor steel or stainless steel, stud link chains are designed to withstand harsh marine environments, including saltwater corrosion and dynamic forces from waves and wind. Their robust construction ensures secure anchoring and mooring, critical for the safety and stability of ships and offshore platforms.
The stud not only reinforces the link but also helps in maintaining the chain's shape, which is crucial when the chain is under heavy tension. This structural integrity minimizes wear and tear, prolonging the service life of the chain and reducing maintenance costs for marine operators.

Hodell-Natco's extensive product range and certifications make them a reliable partner for OEMs and end-users who demand consistent quality and timely delivery. Their chains are widely used in offshore oil and gas platforms, commercial shipping, and heavy-duty industrial applications.
Stud link anchor chains are produced according to strict international standards such as ISO 1704. They are available in various grades, including Grade 2 and Grade 3, which differ primarily in heat treatment processes that enhance strength and durability. Chain diameters typically range from 11mm to 162mm, with lengths per shot around 27.5 meters. Surface finishes include black painting and hot-dip galvanizing to protect against corrosion.
Materials used include:
- Hot-rolled anchor steel (e.g., CM490, CM690)
- Stainless steel grades 316 and 316L
Certifications from major classification societies such as ABS, DNV, GL, LR, BV, NK, KR, and IRS ensure product reliability for marine applications.
The chains' mechanical properties, such as tensile strength, elongation, and impact resistance, are rigorously tested to meet or exceed these standards. This guarantees that the chains can withstand the dynamic loads experienced during anchoring and mooring operations.
The production of stud link anchor chains involves several precise steps:
1. Material Cutting: Steel rods are cut to predetermined lengths to form individual links.
2. Heating: The steel pieces are heated in large furnaces to reach malleability.
3. Forging: Heated steel is forged into link shapes using powerful presses and hammers.
4. Welding: Links are welded, and studs are inserted to reinforce each link.
5. Heat Treatment: Chains undergo heat treatment to relieve internal stresses and improve mechanical properties.
6. Finishing: Surface treatments such as shot blasting, black painting, or galvanizing are applied.
7. Testing: Chains are rigorously tested for tensile strength, impact resistance, and magnetic particle inspection to detect defects.
8. Certification: Final products are certified by classification societies to meet international standards.
This meticulous process ensures that each stud link anchor chain delivers optimal performance in the field. Advanced manufacturing technologies, such as automated forging and robotic welding, have enhanced product consistency and reduced production lead times.
Stud link anchor chains are primarily used for:
- Anchoring large vessels, ensuring they remain securely moored even under severe weather conditions.
- Mooring floating structures such as oil rigs and buoys.
- Offshore construction projects requiring reliable heavy-duty chains.
- Marine civil engineering works including docks and piers.
Their design prevents deformation and twisting, ensuring smooth deployment and retrieval, which is crucial for operational efficiency and safety.
In addition to maritime uses, stud link anchor chains are increasingly employed in industrial applications requiring high-strength chains capable of withstanding harsh environments, such as mining and heavy construction.
Proper maintenance and regular inspection are vital to extending the service life of stud link anchor chains. Routine checks should focus on:
- Corrosion: Look for signs of rust or pitting, especially in galvanized or painted chains.
- Wear: Measure link thickness and check for elongation or deformation.
- Weld Integrity: Inspect welds for cracks or defects using non-destructive testing methods.
- Stud Condition: Ensure studs remain firmly in place without signs of loosening.
Chains subjected to extreme conditions may require more frequent inspections. Proper lubrication and cleaning after use can also prevent premature wear and corrosion.
The stud link anchor chain industry is evolving with advancements in materials and manufacturing techniques. Some notable trends include:
- High-Strength Alloys: Development of new steel alloys that provide higher tensile strength while reducing weight.
- Advanced Coatings: Use of environmentally friendly coatings that offer superior corrosion protection without harmful chemicals.
- Automation: Increased automation in forging and inspection processes to improve precision and reduce human error.
- Digital Tracking: Implementation of RFID tags and digital records for chain traceability and maintenance history.
These innovations contribute to safer, more reliable anchoring solutions and help manufacturers meet the growing demands of the global marine industry.
