Starrett Clamp Only for Machinists - Hardened & Ground Steel Clamp with 1"/25mm. Hold Capacity for 278 V-Block - 278B

This precision Starrett Clamp Only for 278B V-block is designed for machinists and metalworking professionals who require reliable workholding when positioning round or cylindrical materials. Made from hardened steel, the clamp is built for durability and consistent performance in machine shop and inspection environments. When used with compatible V-blocks, it applies downward pressure to hold round stock securely in the V-groove, helping reduce movement during layout, drilling, milling, grinding, or measurement tasks. The threaded screw mechanism allows for controlled tightening and quick adjustment, making it easy to secure workpieces during setup. This clamp is designed for 1" (25 mm) V-block configurations and can be used as a replacement or spare component for existing V-block sets. Its simple, functional design makes it suitable for machine shops, tool rooms, and inspection benches where stable positioning of cylindrical parts is required. Note: This listing includes the clamp only. V-blocks are not included.
