G clamps are a general purpose clamping tool which is ideal for DIY enthusiasts and can be used for many applications in both woodworking and metalworking.

G Clamps or C clamps are the simplest models designed to hold objects in place and prevent any movement. These hand tools have two jaws. The upper edge of the ’G’ acts as one jaw and a threaded screw which comes through a hole at the bottom provides the other jaw for clamping workpieces. Due to their simple build and small size they can be used almost anywhere. They are ideal for woodworking or welding.

You should always use a G clamp which is a suitable size to hold your workpiece, if not there is a chance of bending the frame and damaging the screw. The size can be measured by its jaw opening (how far the mouth of the jaws can open) and the depth. These G clamps from Irwin area available in 4 sizes to choose from:
