Vermont Gage 112108820 Class Zz Plus Plug Gage 8.82 Mm

Product Description

The VERMONT GAGE 112108820 is a Class ZZ Plus plug gage manufactured from tool steel for use in precision dimensional inspection. The gage measures a nominal diameter of 8.82 mm with a tolerance of 0.00508 mm, making it suitable for Go inspection applications where close-tolerance hole verification is required. The 10 microfinish surface coating supports accurate, repeatable contact with the workpiece. Each unit ships with a Certificate of Accuracy traceable to NIST standards. Licensed metrologists, quality technicians, and tool room personnel use this type of gage in production and incoming inspection environments.

This plug gage is designed for Go inspection of holes sized to 8.82 mm in diameter. Typical applications include verifying bored, drilled, or reamed holes during in-process or final inspection on machined components. It is also suited for setting and verifying micrometers, verniers, and other precision measuring devices. The overall length of 2.0000 inches makes it compatible with standard handle sets used in bench inspection and CMM fixturing setups.

Key Features

• Tool steel construction for wear resistance and dimensional stability
• 10 microfinish surface coating for consistent, accurate contact
• Tolerance of 0.00508 mm for high-precision measurement applications
• Certificate of Accuracy included with full NIST traceability
• Conforms to ASME B89.1 standards

Compatibility

Designed for use in Go inspection of 8.82 mm diameter bores and for setting micrometers, verniers, and other precision measuring devices. Compatible with standard plug gage handles used in typical tool room and quality inspection setups.

Installation Notes

Plug gages should be handled by quality technicians or tool room personnel trained in precision measurement procedures. Clean the gage and the workpiece bore before use to prevent debris from affecting the measurement result. Do not force the gage into an undersized bore, as this can damage the gage surface and affect accuracy. Store the gage in its protective case when not in use to prevent nicks and corrosion that would compromise the 10 microfinish surface.
