A universal clamp is a versatile tool used to hold objects firmly in place. It is designed to fit a wide range of objects and can be adjusted to accommodate different shapes and sizes. The clamp typically consists of two jaws that are connected by a screw mechanism, allowing the user to tighten or loosen the grip as needed.

The jaws may be lined with rubber or other materials to prevent damage to the objects being clamped. Universal clamps are used in a variety of applications, including woodworking, metalworking, and laboratory work.

They are known for their versatility, reliability, and ease of use, making them a popular choice for both professional and DIY projects.
