Ring Gages, typically used as "go/no-go" gages for cylindrical parts, or as masters for calibrating other types of  gages.  These are the foundation of Edmunds Gages.   Edmunds ring gages are the finest available because we use only superb quality tool steels, and manufacturing and quality control processes that ensure the best value.  These gages are calibrated at six separate points to verify size and geometry.  Edmunds inch or metric plain ring gages are available in a wide range of sizes, in classes Z, Y, X, XX and a choice of materials to suit your application.  Ring gages from .040 inch (1.02 mm) diameter to 12.000 inch (304.80 mm) diameter are available in steel or chrome.  All are made per the specifications of the American Gage Design (AGD) standards.  Custom configurations and marking are also available upon request.
