The F clamp is a type of joinery clamp with a design resembling the letter "F". It has a fixed guide arm and a sliding clamping arm with a screw mechanism. The advantage of F clamps is a greater range of opening and the possibility of working with larger parts. They provide sufficient clamping force while maintaining low weight and easy handling. They are suitable for a wide range of joinery and assembly work, especially when assembling frames, gluing boards or securing material during machining.
