Vermont Gage 112108000 Class Zz Plus Plug Gage 8mm

Product Description

The VERMONT GAGE 112108000 is a Class ZZ Plus cylindrical plug gage used to verify bore and hole dimensions to tight tolerances in precision metrology and quality control work. Manufactured from tool steel, this gage measures 8.00 mm in diameter with a tolerance of 0.00508 mm and features a 10 microfinish surface on the gaging element. Overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy traceable to NIST standards, making it suitable for calibrated inspection environments. Machinists, quality technicians, and metrologists use this style of gage as part of go inspection routines on production and inspection floors.

This plug gage is suited for go inspection applications where precise bore acceptance or rejection is required. It is also used to set micrometers, verniers, and other measuring devices to a known reference diameter. Typical environments include machine shops, manufacturing quality labs, tool rooms, and calibration facilities. The 8.00 mm diameter targets metric bore applications in general machining, hydraulic components, and precision assemblies where dimensional conformance must be verified before parts advance in production.

Key Features

• Class ZZ Plus tolerance grade — 0.00508 mm tolerance for precise go inspection
• 10 microfinish surface for consistent, repeatable contact with bore walls
• Tool steel construction for hardness and wear resistance in production use
• Conforms to ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability for calibrated inspection records
• Compact overall length of 2.0000 inches for easy handling in confined inspection setups

Compatibility

Designed for go inspection of 8.00 mm diameter bores and for setting micrometers, verniers, and other measuring devices requiring a certified reference diameter. Suitable for use wherever ASME B89.1 Class ZZ Plus plug gage specifications are called out.

Installation Notes

Plug gages are handled and used by quality technicians and metrologists — no installation in the traditional sense applies. Keep the gage clean and lightly oiled when stored to prevent corrosion on the tool steel surface. Do not force the gage into a bore; damage to the gage or workpiece can result. Store the gage in its case and return it for recertification on a schedule consistent with your quality management system requirements.
