Zero Check has been in operation since 1962 manufacturing precision cylindrical plug & ring gages while servicing all facets of industry from automotive to aerospace and military to medical. Since then, custom gaging has been expanded with the acquisition of CNC turning centers, CNC milling, and Wire EDM along with measuring equipment. Custom gaging features such as depth notches, keyways, and flats are now performed in house to reduce delivery times and control quality and our calibration services are offered with quick turnaround times. Gages are available in hardened and double-stabilized steel, stainless steel, carbide and chrome. Zero Check is proud of our strong, long-standing customer relationships built while delivering quality products made right here in the USA.
