Starrett 51313 V-block Clamp 1 in Hardened Steel

Product Description

The STARRETT 51313 is a hardened steel V-block clamp designed to secure round and cylindrical workpieces during layout work, inspection, and stock-holding operations. The clamp features a 90-degree V angle and accepts stock up to 1 inch in maximum V capacity. Overall dimensions are 1-5/8 inches long, 1-1/4 inches wide, and 1-1/4 inches high. The hardened steel construction provides the durability and rigidity required for precision layout tasks. This clamp is designed for use with the STARRETT Model 278 V-block, making it a direct companion accessory for that unit. Machinists, toolmakers, and precision-layout technicians are the primary users.

This clamp is suited for benchtop layout and inspection setups in machine shops, tool rooms, and manufacturing environments. It holds cylindrical or round stock firmly in place while scribing lines, checking concentricity, or performing precision measurements. The compact footprint makes it practical for use in tight setups alongside other layout tooling. It is appropriate for both light production and individual job-shop applications where repeatable, accurate workholding is required.

Installation Notes

Installation and setup of V-block clamps should be performed by qualified machinists or toolroom technicians familiar with precision layout equipment. Ensure the workpiece and V-block surfaces are clean and free of chips or burrs before seating the clamp. Secure the clamp evenly to avoid cocking or misalignment of the workpiece. Do not exceed the rated maximum V capacity of 1 inch, as overloading can damage the clamp or compromise workholding accuracy.
