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.
An F-clamp is also a simple mechanical device used for lifting engine or
transmission parts. The clamp has an adjusting screw to tighten onto the part and a lifting ring to attach a hoist cable.
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.
