C-clamps in use - A traditional C-clamp is usually made of steel. It has a C-shaped frame with a flattened edge on one end and a threaded hole on the other end. A large threaded rod goes through the hole and has a flattened edge on it that is parallel to the flattened edge on the frame. The rod can then be tightened to clamp a work piece between the two flattened edges.
- The tool is referred to as a C-clamp because the frame is shaped like a C. However, it is also known as a "G-clamp" because it can look like a G when the rod is tightened. In the UK and Australia, it is often referred to as a G-clamp and in stagecraft as a "pipe clamp."
- A C-clamp is most often used to securely hold an object to a surface. It can also be used to make work easier by clamping a piece to a workbench. According to technologystudent.com, it can also be used to hold pieces together while glue is drying between them.
- Other types of C-clamps exist besides the traditional style. Lever clamps, locking C-clamps and bar clamps are all derived from the original C-clamp.
- The flattened edges on C-clamps can leave indentations on delicate wood. It is a good idea to use two pieces of scrap wood on the top and bottom of the work piece as a buffer where the clamp is being used.
