Vermont Gage 112109920 Class Zz Plus Plug Gage 9.92 Mm

Product Description

The VERMONT GAGE 112109920 is a Class ZZ Plus plug gage machined from tool steel and used to verify bore diameter during go inspection. It measures 9.92 mm in diameter with a tolerance of 0.00508 mm (0.005 mm), making it suitable for precise dimensional verification in production and quality-control environments. The gage carries a 10 microfinish surface finish. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting the documentation requirements of most quality management systems. Licensed metrologists, machinists, and quality technicians are the primary users of this instrument.

This plug gage is intended for go inspection of 9.92 mm diameter bores in machined components. It is also used to set micrometers, verniers, and other comparative measuring devices where a traceable reference standard is required. Suitable for both production-floor spot checks and metrology lab use, it conforms to ASME B89.1 dimensional gage standards. The compact overall length of 2.0000 inches makes it easy to handle in tight inspection setups.

Key Features

• Class ZZ Plus tolerance grade with 0.00508 mm tolerance for high-accuracy go inspection
• Tool steel construction for wear resistance and dimensional stability
• 10 microfinish surface finish minimizes gauge-to-part surface interaction error
• Conforms to ASME B89.1 gage standards
• Includes Certificate of Accuracy with NIST traceability for quality system documentation
• Compact 2.0000-inch overall length for versatile handling

Compatibility

Designed for go inspection of 9.92 mm diameter bores and for setting micrometers, verniers, and other comparative measuring devices requiring a traceable dimensional reference.

Installation Notes

Plug gages should be handled by qualified inspection or metrology personnel following standard gage-handling practices. Keep the gage clean and lightly oiled when not in use to prevent corrosion and dimensional change. Never force the gage into a bore; excessive insertion force can damage both the gage and the workpiece. Store in a protective case away from temperature extremes to maintain calibration integrity.
