Stud Link Anchor Chains – The Industry Standard for Secure Mooring
Superior Strength & Stability for Marine Applications
Stud link anchor chains are the preferred choice for commercial and industrial vessels due to their enhanced strength, stability, and resistance to deformation. The integral studs in each link provide critical reinforcement, making these chains ideal for:
-
Primary ship anchoring
-
Heavy-duty offshore mooring
-
High-stress marine operations
Key Advantages Over Studless Chains:
✔ Higher Tensile Strength – Withstands greater loads without elongation
✔ Reduced Tangling – Studs prevent twisting during deployment/storage
✔ Better Load Distribution – Minimizes point stress on individual links
✔ Longer Lifespan – More resistant to wear and fatigue
