Vermont Gage 112322070 Class Zz Plus Plug Gage 22.07mm

Product Description

The VERMONT GAGE 112322070 is a Class ZZ Plus plug gage machined from tool steel for dimensional inspection of bored and reamed holes. It checks a 22.07 mm nominal diameter with a tolerance of 0.00508 mm, making it suitable for Go inspection applications where close-tolerance verification is required. The gage ships with a Certificate of Accuracy carrying NIST traceability, supporting quality documentation requirements in production and calibration environments. Machinists, quality technicians, and metrologists use plug gages like this one to confirm that a feature falls within specification before the part advances to the next operation.

This plug gage is intended for Go inspection of 22.07 mm diameter features in manufacturing and inspection settings. Typical applications include verifying bored holes, reamed bores, and other precision cylindrical features on machined components. It is also used as a reference standard when setting micrometers, verniers, and other variable measuring devices. The 2.0-inch overall length suits bench-top inspection work and integrates easily into standard gage-handling fixtures and gage blocks setups.

Key Features

• Class ZZ Plus tolerance grade with 0.00508 mm tolerance for close-tolerance Go inspection
• 22.07 mm nominal diameter machined from tool steel for wear resistance and dimensional stability
• 10 micro-inch surface finish coating supports repeatable, low-friction gage entry
• Includes Certificate of Accuracy with NIST traceability for ISO and quality-system documentation
• Meets ASME B89.1 standards for plain plug gages
• 2.0-inch overall length compatible with standard bench and fixture inspection setups

Compatibility

Designed for Go inspection of 22.07 mm diameter bored or reamed features; also functions as a setting standard for micrometers, verniers, and other measuring devices calibrated to this nominal diameter.

Installation Notes

Plug gages are handled by quality technicians and machinists following dimensional inspection procedures. Clean and deroil both the gage and the workpiece bore before use to prevent false readings and premature wear. Store the gage in its protective case away from temperature extremes to maintain dimensional stability. Never force the gage into an undersized bore, as this can damage the gage surface and invalidate its calibration status.
