Description

An F-clamp is a type of clamp. It is also known as a bar clamp or speed clamp. An F-clamp consists of two horizontal bars joined together by a vertical bar. This gives the clamp an appearance of the letter F. 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.

Similar devices

The F-clamp is similar to a C-clamp in use, but has a wider opening capacity (throat). F-clamps in the industry terminology have the jaws mounted on a flat bar, while a pipe clamp, which has the same construction, is mounted on a pipe, normally of 1/2" or 3/4" diameter.
