Blue Hawk passing link chain is zinc plated, packaged on a reel, and trade size 2/0. It is made of low-carbon steel, which has good wear resistance and lower carbon content than medium- and high-carbon steel. The chain measures 0.19" in diameter and 10' in length per plastic clamshell, and it has a working load limit (WLL) of 450 lb. It is suitable for use as farm and animal chains, and other general purpose applications. This chain has been proof tested for weld, material, and performance quality and is not recommended for use in overhead lifting applications. Chains are connected links or rings in various shapes and lengths, usually made of metal or plastic, that are used primarily for fastening items or pulling loads. They are also used for lifting, rigging, hoisting, binding, suspension, and motion-control applications. A combination of characteristics including material, finish, construction, diameter, length, and breaking strength give each chain its performance capability. Chain materials are selected for properties such as strength, elasticity, conductivity, and chemical- and weather-resistance. Chains can be fitted with accessories including clips, shackles, hooks, links, and swivels among others to prevent tangling, aid guiding, and allow clamping to other chains. Chains are most commonly used in the manufacturing, transportation, oil, mining, agricultural, and construction industries.
