Description: C-clamps, also known as G-clamps, are one type of screw clamps that are designed with a screw mechanism with adjustable jaws for clamping different kinds, shapes, and sizes of workpieces in place. C-clamps are widely used in welding and carpentry and are referred to C or G-clamps according to their shape, which resembles the letter C or G. Like all clamps, C-clamps are constructed from sturdy materials such as cast iron, and steel. Other C-clamps of smaller sizes can be made of pot metal which refers to the alloy of different metals with low melting points. The top end of a c-clamp features a tiny flat edge, and the bottom end has a threaded opening that fits a protruding threaded screw. The C-clamp is used by tightening the threaded screw on the surface of the object being clamped until the required camping pressure is achieved. Apart from woodworking, c-clamps are also the designated types of clamps for hanging stage lighting instruments.Get the best choice of C clamps available in the market today.
