A C-clamp is a type of clamp device typically used to hold a wood or metal workpiece, and are often used in, but are not limited to, carpentry and welding. These clamps are called "C" clamps because of their C shaped frame, but are otherwise often called G-clamps or G-cramps because including the screw part they are shaped like an uppercase letter G.
