This metal clamp is an essential tool for anyone in the Industrial and Scientific field. According to my experience it securely holds my workpiece in place without causing any damage. The 2-inch jaws provide a strong grip, preventing slippage or movement during work .The durable construction makes it a long-lasting tool for repeated use. The only downside is that the screw may require lubrication to avoid sticking. Overall, an excellent addition to any workholding collection..
