Vermont Gage 112106500 Class Zz Plus Plug Gage 6.5 Mm

Product Description

The VERMONT GAGE 112106500 is a Class ZZ Plus plug gage used to inspect bore and hole dimensions to tight tolerances. It is manufactured from tool steel with a 10 microfinish surface finish, giving it the hardness and wear resistance required for repetitive inspection work. The gage carries a tolerance of 0.005 mm and is supplied with a Certificate of Accuracy with NIST Traceability, making it suitable for documented quality-control applications. With an overall length of 2.0000 inches, it is a compact, handheld precision instrument. Licensed metrology technicians, quality inspectors, and tool-room machinists are the primary users of this type of gage.

This plug gage is intended for go inspection of 6.5 mm diameter bores. It is used to verify hole size conformance on machined parts in manufacturing, tool-and-die, and quality-assurance environments. Typical applications include setting and verifying micrometers, verniers, and other measuring devices, as well as direct bore inspection on the shop floor or in the inspection room. It conforms to ASME B89.1 standards, making it appropriate for use in regulated or traceable inspection programs.

Key Features

• Class ZZ Plus tolerance grade with 0.005 mm tolerance for precise go inspection
• Tool steel construction for hardness and long service life
• 10 microfinish surface finish for smooth, repeatable contact with bore surfaces
• Includes Certificate of Accuracy with NIST Traceability for documented QC use
• Conforms to ASME B89.1 dimensional standards
• Suitable for setting micrometers, verniers, and other measuring devices

Compatibility

Designed for go inspection of 6.5 mm diameter bores and for use with micrometers, verniers, and other measuring devices requiring a traceable reference standard.

Installation Notes

Plug gages are handled and used by metrology technicians and quality inspectors, not installed in the traditional sense. Keep the gage clean and lightly oiled when not in use to prevent corrosion of the tool steel. Do not force the gage into a bore; it should enter only under its own weight for a proper go check. Store in a protective case away from temperature extremes to maintain dimensional stability.
