A G clamp, also known as a C clamp or a G cramp, is a type of mechanical tool used to secure and hold objects together. It is typically made of steel and consists of two jaws, one fixed and one adjustable, which are brought together by a screw mechanism. The fixed jaw is attached to a frame or body, while the adjustable jaw can be moved to accommodate objects of varying sizes. G clamps are commonly used in woodworking and metalworking to hold pieces of material together while they are being cut, drilled, or otherwise worked on. They can also be used in a variety of other applications, such as welding, automotive repair, and construction. G clamps come in various sizes and styles to accommodate different needs and uses. Some are designed with a swivel pad to help prevent damage to delicate surfaces, while others may have a heavy-duty construction for more demanding applications. They are an essential tool for any workshop or DIY project where holding objects securely in place is necessary.
