A plumber uses a chain wrench to tighten a large pipe fitting.

Definition

Noun: A type of pipe wrench that uses a chain to grip and turn cylindrical objects, such as pipes or rods. It is a tool primarily used in plumbing and metalworking.

Usage

A chain wrench is used to provide a strong, adjustable grip on smooth, round surfaces where a standard wrench might slip. The chain is looped around the object and tightened, allowing the user to apply torque.

Examples
