Clamps

An F-clamp, also known as a bar clamp or speed clamp and a "G-clamp", is a type of clamp. The name comes from its "F" shape. The F-clamp is similar to a C-clamp in use, but has a wider opening capacity (throat). This tool is used in woodworking while more permanent attachment is being made with screws or glue, or in metalworking to hold pieces together for welding or bolting.

An F-clamp consists of two horizontal bars joined together by a vertical bar. There is a large screw on the lower bar to allow for the clamp to be tightened.  F-clamps are adjustable which allows for them to be used on larger scale objects without the need for a large screw.
