Vermont Gage 112107100 Class Zz Plus Plug Gage 7.1 Mm

Product Description

The VERMONT GAGE 112107100 is a Class ZZ Plus plug gage designed for dimensional inspection of 7.1 mm diameter bores and holes. Machined from tool steel with a 10 microfinish surface coating, it delivers the repeatability and wear resistance required in production and quality-control environments. Tolerance is held to 0.005 mm, meeting ASME B89.1 standards. Each unit ships with a Certificate of Accuracy traceable to NIST, making it ready for use in calibrated inspection programs without additional certification steps. Machinists, quality technicians, and tool-room professionals use this gage to verify bore size quickly and reliably.

This plug gage is suited for go inspection applications in machine shops, manufacturing facilities, and metrology labs. It is also used as a setting standard for micrometers, verniers, and other measuring devices that require a known reference diameter. The 2.0-inch overall length fits standard gage handle configurations. It is appropriate for both incoming inspection and in-process quality checks wherever a 7.1 mm bore tolerance must be confirmed to ASME B89.1 requirements.

Key Features

• Class ZZ Plus tolerance of 0.005 mm for precise go inspection
• Tool steel construction for durability and wear resistance in production environments
• 10 microfinish surface coating for smooth, consistent gage entry
• Meets ASME B89.1 dimensional standards
• Includes Certificate of Accuracy with NIST traceability
• Compatible with standard gage handle configurations at 2.0 inches overall length

Compatibility

Designed for use as a go plug gage for 7.1 mm diameter bores. Also used as a setting reference for micrometers, verniers, and other precision measuring devices requiring a calibrated diameter standard.

Installation Notes

Plug gages should be handled by quality technicians or tool-room personnel familiar with precision measurement practices. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Never force a plug gage into a bore; resistance indicates the bore is undersize and forcing may damage the gage or the workpiece. Store in a protective case away from temperature extremes to maintain dimensional stability.
