Starrett 50584 Adjustable Parallel Set 4 Piece with Case

Product Description

The STARRETT 50584 is a 4-piece adjustable parallel set designed for precision layout, setup, and machining work. Each parallel in the set is independently adjustable, allowing the technician to dial in exact height settings across a range of 3/8 inch to 1-5/16 inch. Individual piece lengths span from 1-3/4 inches to 3-9/16 inches, and each parallel measures 9/32 inch thick. The set ships with a protective storage case to keep pieces organized and free from damage between uses. Machinists, toolmakers, and precision metalworkers are the primary users of this type of tooling.

Adjustable parallels are used to support workpieces in milling vises, on surface plates, and in grinding setups where fixed parallels cannot provide the exact height needed. The 50584 set covers a broad enough range to handle a wide variety of workpiece geometries in job shop and production environments. The included case makes the set practical for bench use and transport between workstations or field service locations.

Installation Notes

Adjustable parallels are installed by machinists and toolmakers during workpiece setup prior to machining or grinding operations. Always clean the vise bed, parallel surfaces, and workpiece contact faces before seating the parallels to ensure accurate support. Do not overtighten the vise jaw against the parallels without confirming the workpiece is fully seated. Inspect each parallel for burrs or wear before use, as surface damage will affect setup accuracy.
