Vermont Gage 112106880 Class Zz Plus Plug Gage 6.88mm

Product Description

The VERMONT GAGE 112106880 is a Class ZZ Plus plug gage machined from tool steel for precision bore inspection and dimensional verification. It features a 6.88 mm diameter with a tolerance of 0.00508 mm and a 10 microfinish surface, providing accurate, repeatable measurements in high-demand metrology and quality-control environments. The gage ships with a Certificate of Accuracy traceable to NIST, confirming conformance to ASME B89.1 standards. Machinists, quality technicians, and tool room professionals rely on this type of gage for go inspection workflows where tight dimensional control is required.

This plug gage is suited for go inspection of bored, drilled, or reamed holes with a 6.88 mm nominal diameter. It is also used to set and verify micrometers, verniers, and other precision measuring devices in production, tool room, and inspection lab settings. The 2.0000-inch overall length fits standard handle configurations. Applications span general manufacturing, aerospace component inspection, and any precision machining operation where hole diameter must be confirmed within close tolerances.

Key Features

• 6.88 mm diameter with 0.00508 mm tolerance for precise go inspection
• 10 microfinish surface for accurate, low-wear contact with bore surfaces
• Tool steel construction for durability in production inspection environments
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 dimensional gage standards
• 2.0000-inch overall length compatible with standard plug gage handles

Compatibility

Designed for use in go inspection of 6.88 mm nominal diameter holes and for setting micrometers, verniers, and other precision measuring devices. Fits standard plug gage handle systems sized for this diameter class.

Installation Notes

Plug gages are handled and used by quality technicians and machinists following standard metrology practices. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Do not force the gage into a bore; go gages should enter under their own weight or with minimal hand pressure. Store in a protective case away from temperature extremes to maintain dimensional stability.
