Cylindrical Gages

Cylindrical plug and ring gages are fundamental tools in precision manufacturing and quality control. They are used to verify the accuracy of hole and shaft dimensions. Cylindrical plug gages are used to check the internal diameter (ID) of holes. Cylindrical ring gages are used to check the outside diameter (OD) of shafts or cylindrical parts. They both come in "go" and "no-go" configurations to determine if a hole or shaft is within specified tolerances. Judge Tool & Gage offers cylindrical gages in both metric and inch measurements in a variety of types, both individual gages and sets.
