At Harshman Gauges & Engineering Company, we provide high-quality Go and No-Go Plain Plug Gauges designed to inspect and verify internal hole dimensions with exceptional accuracy. These gauges ensure components conform to specified tolerances, preventing assembly errors and enhancing product reliability.
Go and No-Go Plain Plug Gauges are precision instruments used to check internal diameters of holes in mechanical components. The “Go” plug confirms that the hole is within minimum limits, while the “No-Go” plug ensures it does not exceed maximum limits, guaranteeing dimensional conformity.
