F-clamp

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.

[2] 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.

[citation needed] The F-clamp is similar to a C-clamp in use, but has a wider opening capacity (throat).
