Clamps are versatile tools that serve to temporarily hold work securely in place.
They are used for many applications including carpentry, woodworking, furniture making, welding, construction and metal working. Clamp styles include C-clamps, bar clamps, pipe clamps, and handscrews. Bar clamps have adjustable arms that are easily widened or narrowed to fit the work piece and, therefore, requires fewer turns of the screw spindle, compared to a C-clamp, to hold the piece tightly. DO Wear safety glasses or a faceshield. Ensure that the pressure plate and anvil parts of the clamp are in full contact with the workpiece before tightening.
