Stud link anchor chains are a type of heavy-duty chain commonly used for anchoring and mooring vessels. They have a central stud in each link that helps to prevent kinking, deformation, and fouling. These chains are known for their strength and are often preferred for large vessels and applications where significant loads are involved.
Fishing chains have three specifications: short link chian, middle link chain and long link chain. Different types of fishing chains have different features.
Studless Fishing Anchor Chain are 62.5% load verified at break, very durable and able to withstand extreme and harsh weather use, it is also corrosion-resistant, ideal for use in saltwater environments. There are Short Link, Mid Link and Long Link to choose from.

The Sand Anchor has is a conventional anchor with solid construction to withstand high load.It has high holding power and weight ratio and very suitable for seabed of sand and mix Soil.
Mooring connection plates are manufactured using alloy grade material and followed by full heat treatment process.The durability ensures that the plates can withstand exposure to saltwater, reducing maintenance needs and extending the lifespan of the aquaculture setup.
Mooring shackles are manufactured with alloy steel by following ISO9001 Quality Control System. With our years know-how on forging, heat treatment and hot dip galvanized, it is ensured the mooring shackle avoid any Hydrogen Embrittle-ment and offer a longer fatigue life of safe performance compared to EN13889 requirement and safety.
The Stingray Anchor is a high-efficiency drag embedment anchor designed for aquaculture and marine mooring. With holding power exceeding 40 times its own weight, it significantly outperforms conventional anchors of similar size.
Rope K3 Thimble is used for aquaculture mooring, where the surface needs to be heat-treated to protect wire, fibre or synthetic ropes.
The 12.5mm Stud Link Anchor Chain is a heavy-duty marine chain primarily used in ship anchoring and mooring systems. Standard length (short link): typically supplied in 27.5-meter (15 fathom) lengths, connectable using Kenter shackles.
AM3 is a designation for a grade of stud-link anchor chain, specifically referring to a high-strength steel chain used for ship anchoring and mooring. These chains are designed for durability and reliability in demanding marine applications, often used on large vessels or in harsh environmental conditions.
Stud link anchor chain AM2 is a specific type of anchor chain widely used in marine applications. It's characterized by having a stud (a crossbar or bar) within each link, adding strength and preventing kinking or twisting. AM2 is a designation within the marine industry for a specific grade of this chain, indicating its strength and material properties.

1. What is an anchor chain swivel assembly (swivel forerunner)?
An anchor chain swivel assembly (also called a swivel forerunner) is a component installed between the anchor and the anchor chain. Its primary function is to allow the chain to rotate freely during deployment and recovery, preventing twisting, kinking, or tangling. It also helps distribute load evenly for smoother anchoring operations.
2. What is the difference between 3-link, 4-link, and 5-link swivel forerunner?
| Configuration | Structure | Best For |
| 3-link | E + SW + EL + C | Small to medium-sized vessels, yachts, compact design, cost-sensitive projects |
| 4-link | E + C + EL + SW + EL | Larger chains and heavier mooring requirements, more length and flexibility |
| 5-link | E + EL + SW + EL + C | Large vessels, smoother load transfer |
The 3-link or 4-link swivel forerunner is the most common swivel connector in use today due to its optimal design.
3. Can the 3-link assembly be customized to my specifications?
Yes, absolutely. The 3-link swivel assembly can be fully customized to match your anchor chain system.
We can adjust:
- Each link dimension – based on your chain diameter (d)
- Material grade – U2 (AM2) or U3 (AM3), matching your chain
- Surface finish – hot-dip galvanized or black bitumen coating
- Certification – LR, ABS, DNV, BV, CCS, NK, KR, RINA, RS, IRS
For example, if you have a specific chain diameter (say 22mm or 32mm), we will calculate and produce each component (End Link E, Enlarged Link EL, Swivel SW, Common Link C) to match your system perfectly.
4. What grades and diameters are available?
Available in U2 and U3 grades, with diameters ranging from 16mm to 132mm. Custom sizes are available upon request.
For U2/U3 grades, we can supply the swivel assembly with full classification society certification.
5. What certifications can you provide?
Class certificates from ABS, LR, BV, DNV, CCS, NK, KR, RINA, RS, IRS are available upon request. Mill test certificates and third-party inspection reports can also be provided.
