g clamp
A G clamp, also known as a C clamp, is a versatile and indispensable tool in woodworking, metalworking, and general construction applications. This robust fastening device features a distinctive G-shaped frame with a fixed jaw at one end and an adjustable screw mechanism at the other. The design allows for precise pressure application through a threaded screw that can be tightened or loosened to secure workpieces firmly in place. Modern G clamps are typically constructed from high-grade steel or malleable iron, offering exceptional durability and resistance to deformation under pressure. They come in various sizes, ranging from small 2-inch models for delicate work to industrial-grade 12-inch versions capable of handling heavy-duty applications. The clamp's wide opening capacity, combined with its deep throat depth, enables it to accommodate materials of different thicknesses and reach into areas that might be inaccessible to other clamping tools. The swivel pad at the end of the screw prevents marring of work surfaces, while the rigid frame ensures consistent pressure distribution throughout the clamping process.
