The H-Lift Stainless Steel DIN 766 Link Chain is a standardized, short-link chain renowned for its reliability and excellent corrosion resistance in demanding marine and industrial environments.
Manufactured to DIN 766 specifications, ensuring consistent dimensions for general-purpose engineering and maritime applications.
Premium stainless steel construction provides superior protection against rust, chemicals, and harsh saltwater elements.
Short link configuration offers greater density and flexibility, making it highly suitable for boat mooring, securing, and general utility.
Available in wire diameters ranging from 2mm to 13mm to accommodate various sizing and environmental requirements.
Marine Anchor Chain | Calibrated Short Link | AISI 316 / 304
The Stainless Steel DIN 766 Chain is a premium, globally recognized standard for marine anchoring. Manufactured to precise dimensional tolerances, this calibrated short-link chain is engineered specifically to engage smoothly with motorized marine windlass gypsies without jamming. Its high-polished finish ensures exceptional corrosion resistance in harsh saltwater environments.
📐 Calibrated Standard
Manufactured to the German DIN 766 specification. Every link is strictly calibrated to precise dimensional tolerances, guaranteeing seamless operation over windlass sprockets.
🛡️ Premium Material Grades
AISI 316: The preferred choice for marine use, offering superior resistance to saltwater pitting and chlorides. AISI 304: Suitable for architectural and less severe outdoor environments.
✨ High-Polished Finish
Features a smooth, highly polished surface that not only looks great on luxury yachts but also enhances corrosion resistance by eliminating microscopic surface pitting where rust can start.
🔗 Compact Short Link Design
The tight, short-link profile prevents the chain from knotting, twisting, or binding upon itself, ensuring reliable deployment and retrieval in heavy industrial and marine anchoring applications.
Q: What makes DIN 766 chain different from other short link chains?A: DIN 766 is a precise, calibrated standard. The links are manufactured to strict dimensional tolerances specifically so they can engage smoothly with the gypsy (sprocket) of a marine windlass without jamming or slipping.
Q: Should I use 304 or 316 stainless steel for my boat anchor?A: You should always use AISI 316 stainless steel for boat anchors and marine applications. 316 contains molybdenum, which provides significantly better resistance to saltwater corrosion and chloride pitting compared to 304.

Chain Grade Guide
What is the Difference Between Welded Chain Grades?
🚫 Carbon Steel ChainGrades 30, 43, 70 Used for tie-downs, towing, and securement. NEVER used for overhead lifting.
✅ Alloy Steel ChainGrades 80, 100 Specifically designed and heat-treated for Overhead Lifting and Sling Assemblies.
How is "Grade" Calculated?
The grade number represents the chain's tensile strength (mean stress value). It is calculated by dividing the tensile force (Newtons) by the cross-sectional area of the two links ($mm^2$).
As the Grade Increases:
The material becomes harder and more resistant to abrasion.
The Strength-to-Weight ratio increases (more lifting power, less weight).
The Working Load Limit (WLL) increases significantly.
Towing, general utility, load securement. Stronger than G30.
NO
Grade 70 (Transport)
Heat-Treated Carbon
Heavy Duty Securement. Standard for trucking tie-downs. Identified by Gold/Yellow finish.
NO
Grade 80 (Alloy)
Alloy Steel
Standard Lifting Slings. High ductility (stretch) to absorb shock.
YES
Grade 100 (Premium)
Alloy Steel
Heavy Lifting. 25% stronger than G80. Harder surface for abrasion resistance.
YES
Common Problems & Critical Safety Warnings
Even with the correct grade, misuse can lead to catastrophic failure. Ensure your riggers are trained to avoid these three common hazards:
⚠️ 1. The Hoist Chain Trap
A frequent and dangerous mistake is using the load chain inside a hoist to wrap around a load.
The Design: Hoist load chain is hardened specifically to fit internal sprockets (tight tolerances). It lacks the ductility (stretch) required for a sling.
The Risk: Wrapping it around a load deforms the links. When retracted, the deformed links can snap or destroy the internal hoist mechanism.
⚠️ 2. The "Gold Chain" Error
Using Grade 70 (Gold) chain for overhead lifting is a common error because the chain looks robust.
Why it Fails: Grade 70 is heat-treated for abrasion resistance (for rubbing against truck beds), not for the elongation needed to absorb the dynamic shock of a crane lift. It may snap suddenly without warning.
⚠️ 3. General Neglect
Alloy chain is tough, but not invincible. Proper storage and inspection are vital.
Corrosion: Leaving chain on damp shop floors promotes pitting and stress corrosion cracking.
Inspection: Chains must be inspected regularly for nicks, gouges, and elongation (stretching).
