C-clamps are versatile tools used to hold objects tightly together. They consist of a C-shaped frame with a screw mechanism that allows for adjustable pressure. Commonly made of metal, they are often used in woodworking, metalworking, and construction to secure materials while cutting, drilling, or assembling. These clamps come in various sizes and can accommodate different thicknesses of materials. The design ensures a strong grip without damaging the surfaces being clamped. C-clamps are essential for both professionals and DIY enthusiasts, making tasks easier and more precise when working with wood, metal, or other materials.
