Purpose: G-clamps are hand tools used to secure workpieces firmly in place, often during tasks like gluing, assembly, or other woodworking and metalworking applications.
Construction: They typically consist of a G-shaped (or C-shaped) frame, a threaded spindle, and a swivel pad.
Operation: The screw mechanism is tightened to apply pressure, clamping the object(s) between the swivel pad and the fixed jaw of the frame.
