A screw clamp is a simple yet effective tool used to hold objects tightly together. It consists of a metal frame with a screw mechanism that allows you to adjust the pressure applied to the items being clamped. This makes it ideal for woodworking, metalworking, and various DIY projects, ensuring that pieces stay in place while you work on them. These clamps come in different sizes and styles, including the popular C-clamp and bar clamp. They are essential for tasks like gluing, drilling, or cutting, providing stability and precision. With a screw clamp, you can easily secure materials, making your projects safer and more efficient.
