Mechanical clamps are devices used to hold objects securely in place. They come in various shapes and sizes, designed for different applications, such as woodworking, metalworking, and assembly tasks. Common types include C-clamps, bar clamps, and toggle clamps, each offering unique features to accommodate specific needs. These clamps work by applying pressure to the materials being held, preventing movement during cutting, drilling, or other processes. They are essential tools in workshops and manufacturing settings, ensuring precision and safety while working with various materials, including wood, metal, and plastic.
