Improve safety with your lifting operations with high-quality grade 80 chain hooks, such as US Cargo Control's 1/2" Self Locking Swivel Hooks. Also known as an industrial swivel hook or lifting swivel hook, our self locking hooks have a locking mechanism that easily locks the hook into place, ensuring the hook will not open under heavy load. In other words, when you put a load on it, the hook snaps shut and will not release. The grade 80 swiveling hooks helps reduce risk of the load falling out, and the potential for work-site accidents. The hook has a swivel attachment that allows you to rotate the hook to simplify the loading process and prevent your chain or other rigging hardware from becoming twisted. Use the hooks for lifting jobs, load binding applications, and trailers, as well as in industries including construction, industrial, manufacturing, and offshore oil and gas. The forged hooks are made of grade 80 forged alloy steel, then painted to withstand the elements. It has a working load limit of 12,000 pounds, and is forged and stamped clearly with chain size and chain grade information. Meets or exceeds ASTM A952 / A952M & ASME B30.10 requirements.
