A clamp is a device or tool that is used to hold things tightly in place. You can use a clamp to hold two pieces of wood together while you glue them, or to hold a piece of metal steady while you cut it with a saw. Clamps come in different shapes and sizes, and they can be made of metal, plastic, or other materials. Generally, you can use a clamp whenever you need to secure something in place temporarily.
