C-clamps, also known as G-clamps, feature fixed-width, C-shaped frames with adjustable hand screws that can be tightened or loosened to secure workpieces. They are commonly used in carpentry applications to hold material to the work surface while cutting or drilling, and they can also help to hold joints together during glue-ups. They are also suitable for use in metalworking applications such as welding or grinding. The metal body construction makes them highly durable and warp-resistant. Long-reach G-clamps feature an extended throat design that can help apply clamping pressure near the center of the material for added stability.
