DIN 766 Stainless Steel Anchor Chain for Boat Anchoring
DIN 766 Stainless Steel Anchor Chain for Boat Anchoring
TheDIN 766 stainless steel anchor chain is a calibrated short-link round steel link chain manufactured to German standard DIN 766. Available in 316 and 304 stainless steel, this marine anchor chain is designed for yacht and ship anchor windlass systems, providing smooth, even feeding through the chain gypsy. Mirror polished surface finish ensures excellent saltwater corrosion resistance and a clean, premium appearance.
What Is a DIN 766 Anchor Chain?
DIN 766 is the German standard for short-link calibrated chain, commonly used in anchor and windlass applications. The links maintain consistent dimensions so the chain feeds evenly and reliably through the anchor windlass gypsy, reducing jerky running and wear. In stainless steel (AISI 316 or 304) it is a corrosion-resistant choice for saltwater anchoring on leisure yachts and boats.
Marine Applications
Note: Typical uses based on industry practice; selection should be in line with vessel size, windlass rating and anchoring conditions.
| Application | Typical Use |
|---|---|
| Yacht anchor chain | Main anchor rode for leisure boats |
| Fishing boat anchoring | Reliable anchor line for small craft |
| Windlass systems | Feed chain smoothly through the chain gypsy |
| Mooring & guard chain | Non-lifting tethering and guarding uses |

FAQ
Why choose stainless steel for an anchor chain?
Stainless steel (316 or 304) provides excellent corrosion resistance against saltwater and chloride attack, keeping the chain stronger and better-looking for longer in marine environments compared to plain carbon steel.
What does"calibrated"mean in DIN 766?
Calibrated means the chain links maintain consistent, uniform dimensions, allowing smooth and even feeding through the anchor windlass chain gypsy with reduced wear.
What link sizes are available?
Standard sizes are 4mm, 6mm, 8mm, 10mm, 12mm, 13mm, 14mm and 16mm. Other dimensions can be manufactured to custom specifications.
Is it suitable for lifting?
No. DIN 766 anchor chain is designed for anchoring and non-lifting applications, not for overhead lifting. Use approved lifting chain for load handling.
Does it come with certification?
We do not claim classification society approval, but the product complies with classification society rules and can be supplied with material certificates and third-party inspection.
