US Type Forged Screw Pin Chain Shackle T210/S210 Capacities 1/3 to 85 tons. Hot dip galvanized or electric galvanized. Drop forged, quenched and tempered with alloy pins. Working load limit permanently shown on every shackle. Max proof load is 2.2 times of the working load limited. Min. Breaking strength is 6 times or 4 times of the W.L.L as requirement.
The 1/3-85T G210 Marine-Grade Screw Pin Chain Shackle Rigging represents the gold standard in heavy-duty lifting components, engineered for the most demanding maritime, offshore, and industrial applications. Constructed from G210 carbon steel—a high-strength alloy optimized for tensile performance—and finished with a hot-dip galvanized coating, this shackle combines exceptional strength with unrivaled corrosion resistance.
Compliant with ASME B30.26 (the global standard for lifting hardware) and DNV GL (a leading maritime certification body), it is designed to handle static and dynamic loads in high-stress environments. From deep-sea oil rigs to shipyards and construction sites, this shackle delivers reliable performance where failure is not an option.

Marine-Grade Corrosion Resistance:
The hot-dip galvanized coating is applied through a process where the shackle is fully immersed in molten zinc, creating a metallurgical bond that forms a thick, uniform protective layer (80–100 μm). This coating meets ISO 12944 C5-M standards—specifically designed for offshore and marine environments—providing 25+ years of service life in saltwater conditions. Unlike electroplated coatings, hot-dip galvanizing covers recessed areas and threads, ensuring complete corrosion protection.
High Strength and Reliability:
G210 carbon steel is selected for its exceptional tensile strength of 690 MPa, making this shackle capable of handling loads from 1/3 to 85 tons (Working Load Limit). Its bow and pin are forged from a single piece of steel, eliminating weak points caused by welding or joining. Compliance with ASME B30.26 ensures rigorous testing for fatigue resistance, ensuring reliable performance under repeated loading—critical for rigging applications in shipyards and construction.
Wide Temperature Compatibility:
Operating from -40°C to +200°C, this shackle performs in extreme climates. In Arctic shipping lanes, it resists brittleness in sub-zero temperatures, while in desert oil fields, it maintains strength despite intense heat. This stability makes it suitable for global operations, from offshore platforms in the North Sea to tropical ports in Southeast Asia.
Easy Installation:
The screw pin design allows for quick, tool-free assembly and disassembly. The pin features a self-locking thread mechanism that prevents loosening under vibration or dynamic loads—a critical safety feature in maritime applications. A hexagonal head on the pin ensures secure tightening with standard wrenches, while the smooth bow interior minimizes wear on connected chains or ropes.
Safety-Compliant:
DNV GL certification validates its suitability for maritime use, ensuring compliance with international safety regulations. The 6:1 safety factor—meaning it can withstand six times its rated load before failure—provides a substantial buffer against unexpected overloads, such as sudden cargo shifts or equipment malfunctions. Each shackle is individually proof-tested at 125% of its WLL before leaving the factory.
Marine Industry: Ships use these shackles to connect anchor chains to hulls, ensuring secure mooring in stormy conditions. Offshore oil rigs rely on them to anchor drill pipes and risers, withstanding constant submersion and wave-induced vibration.
Construction: High-rise building projects use them to rig cranes and lift steel beams, providing stable connections during precision placement. Bridge construction teams employ them to hoist precast concrete segments, ensuring safe alignment over waterways.
Logistics: Ports and container terminals use these shackles to secure cargo containers to ships and trucks, preventing movement during transit. Warehouses employ them in overhead crane systems, lifting heavy pallets with precision.
Mining: Underground mines use these shackles to stabilize conveyor systems and support structures, withstanding dust, moisture, and heavy loads. Surface mining operations employ them in dragline rigging, ensuring reliable performance in rugged conditions.
In a recent deep-sea drilling project, these shackles anchored blowout preventers to the ocean floor, operating at depths of 1,500 meters. Despite extreme pressure and saltwater exposure, they maintained integrity for over two years, demonstrating their reliability in the harshest marine environments.
