A mechanical clamp is a device used to hold objects tightly together to prevent movement or separation. It typically consists of two jaws that can be adjusted to fit various sizes of materials, such as wood or metal. Mechanical clamps are commonly used in woodworking, metalworking, and construction to secure pieces during assembly or while cutting. These clamps come in various types, including C-clamps, bar clamps, and pipe clamps, each designed for specific applications. They are essential tools in workshops and factories, providing stability and precision in tasks like gluing, drilling, or welding. Proper use of mechanical clamps enhances safety and efficiency in various projects.
