A US Standard G402 Drop Forged Carbon Steel Universal Swivel Hook for Chain is a heavy-duty rigging component designed for lifting, hoisting, and load-handling applications where rotation and flexibility are required.1. Product DescriptionThe G402 swivel hook is a forged steel connecting device that links chains, slings, or lifting assemblies to loads while allowing 360° rotation. This swivel action prevents twisting, kinking, and undue stress on the chain or load during lifting operations.
2. Key Features
1. Material & Construction Made from drop-forged carbon steel (sometimes alloy steel for higher grades) Forging process ensures: High strength Toughness and durability Resistance to deformation under heavy loads 2. Swivel Mechanism Integrated swivel eye or bearing allows full rotation under load Reduces: Chain twisting Load imbalance Wear and fatigue 3. Load Capacity Designed with a Working Load Limit (WLL) depending on size Typical safety factor: 5:1 (ultimate strength is 5× WLL) Available in multiple sizes to match chain diameters 4. Surface Finish Common finishes include: Hot-dip galvanized (corrosion resistance) Painted or powder-coated options 5. Safety Features Often equipped with: Safety latch (prevents accidental disengagement) Smooth hook profile to reduce stress points
3.Typical Applications Lifting and rigging operations Construction and industrial handling Marine and offshore applications Towing and recovery systems Material handling with chain slings
4. General Specifications (Typical) Chain sizes: ~1/4″ to 1″ and larger Working Load Limit: ~850 lbs to 12,500 lbs (depending on size) Rotation: 360° swivel Design standard: U.S. G402 specification 5. How It Works (Simple Explanation)
The hook attaches to a chain or lifting device via a swivel eye, allowing the hook to rotate freely. When lifting a load, this rotation prevents the chain from twisting, which:
Improves safety Extends equipment life Ensures smoother lifting operations
