The marine boat stud anchor chain is a type of anchor chain specifically designed for ships. The marine boat stud anchor chain is equipped with crossbars, which results in a strength approximately 20% greater than of boat stud less anchor chain under the same size and material conditions. And, it has less deformation and is less prone to tangling under storage.
We can provide this marine boat stud anchor chain at the diameter range of 17.5-162mm with different grade.
And, marine society class certificate of CCS, ABS, LR, GL, NK, RS, DNV, KR, BV, RINA for this boat stud anchor chain are available.
The surface can be black paint or Galvanized.
Application scenario of this marine boat stud anchor chain “
Due to its characteristics such as high strength, small deformation and convenient storage, the marine boat stud anchor chain is widely used in the mooring and anchoring of modern large and medium-sized ships. Whether it is at the port for berthing or during offshore operations, the marine boat stud anchor chain can provide a reliable fixation effect, ensuring the safe berthing of the ships.

Q1: What is the function of the stud in stud link chains?
A: The stud's core function is stress distribution. When tensioned, it prevents excessive deformation and inward collapse of links, evenly dispersing forces across the chain. This significantly enhances tensile strength and fracture resistance.
Q2: High-strength steel vs. stainless steel?
A: Depends on budget and environment:
Steel: Cost-effective solution with galvanizing (mainstream choice)
Stainless steel: Superior corrosion resistance, extended service life, near-zero maintenance – ideal for special vessels/harsh environments (e.g., chemical tankers, desalination plants)
Q3: Why are class certificates critical?
A: Class certificates are proof of compliance with international/national safety codes (e.g., SOLAS). Without certifications the boat can’t pass the vessel inspections.
Q4: What tension load can your chains withstand?
A: Breaking load varies by Diameter (36-162mm),Material grade (R3/R4/etc.)and Manufacturing standard.We provide chains with certified breaking load data for every specification.
Q5: When to replace anchor chains?
A: Conduct regular inspections for:
① Wear: Diameter reduction exceeding class limits
② Deformation: Bent/twisted links
③ Cracks: Surface defects
④ stud damage: Loose/welding failures
⑤ Severe corrosion: Especially non-stainless chains
