Attaching an anchor to a chain involves securing the anchor to the end of the anchor chain using a shackle or swivel. Anchor chains provide weight and durability, helping the anchor set firmly on the seabed. The chain also reduces strain on the anchor rode and vessel by absorbing shocks from waves and currents.

Size: 12.5 mm to 152 mm diameter

Grade: Grade 2, Grade 3, ORQ, K3, K4, R3, R4, R5

Material: High-tensile steel, carbon steel, or alloy steel

Viscosity: Not applicable (solid metal construction)

Buoyancy: Negative (sinks in water due to high density)

Breaking Load: Varies by size and grade (e.g., 12.5 mm Grade 3 ~ 68 kN)

Proof Load: Typically 40-50% of breaking load

Surface Treatment: Hot-dip galvanized or painted for corrosion resistance

Link Types: Studlink or studless (common for marine anchors)

Certification: ABS, DNV, LR, or other marine classification standards

Shackle Compatibility: Matched to chain size (e.g., D-shackles, anchor shackles)

Welding: Flash butt welding or resistance welding for link integrity

Weight: Varies by size (e.g., 12.5 mm chain ~ 3.5 kg/m)

Corrosion Resistance: Enhanced by galvanization or special coatings

Testing: Proof load tested and non-destructive tested (NDT) for quality assurance
