Quick Summary

Figure 1: coil and stud-link chains

A coil chain is a flexible connector made of a series of looped and welded metal links, typically formed from bent oval-shaped bars. Historically, these bars were made of wrought iron, but steel is now more common. Coil chains were traditionally used in applications like slings and cranes, though they have been increasingly replaced by wire rope. A variation, the stud-link chain, features a bar across the inside of each link, adding weight and preventing kinking, making it suitable for ship anchor chains.1

The term "coil" can also refer to a series of loops or a spiral shape, such as in a coil spring or the windings of wire in an electromagnet.23
