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.

  • Precision Clamp for V-Block Workholding - Designed primarily to hold round or cylindrical material in precision V-blocks during layout, drilling, milling, or grinding operations.
  • Hardened Steel for Shop Durability - Made of hardened steel to withstand frequent tightening and harsh shop use. Built to retain clamping strength and dependability in severe machining conditions.
  • Compatible with 1" (25mm) V-Block Setups - Engineered for use with 1" / 25mm capacity V-blocks. Ideal as a replacement clamp or spare when maintaining multiple workholding setups.
  • Secure Crew Clamp Design - Features a threaded screw with a knurled head for easy tightening and controlled pressure. Allows machinists to quickly secure workpieces without damaging surfaces.
  • Ideal Replacement Part - Perfect for replacing worn clamps or finishing off an existing V-block set in machine shops, tool rooms, and inspection departments.
