Vermont Gage 112102000 Class Zz Plus Plug Gage 2 Mm

Product Description

The VERMONT GAGE 112102000 is a Class ZZ Plus cylindrical plug gage used to verify bore and hole diameters in precision machining and quality control environments. The gage measures 2 mm in diameter and holds a tolerance of 0.005 mm, with a 10 microfinish surface on the gaging member. Manufactured from tool steel for hardness and wear resistance, this plug gage is suitable for high-repetition inspection tasks where dimensional accuracy is critical. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documentation requirements in ISO and AS9100 quality systems. Machinists, quality technicians, and tool room personnel are the primary users.

This plug gage is intended for go inspection applications on 2 mm diameter bores and holes. It is also used to set and verify micrometers, verniers, and other precision measuring devices where a calibrated reference of known diameter is required. The Class ZZ Plus tolerance designation makes this gage appropriate for inspection of standard commercial-grade work where go/no-go criteria must be documented. Typical install scenarios include incoming inspection, in-process quality checks on machining centers, and tool room calibration setups. The compact size suits tight-tolerance small-bore work in both job shop and production environments.

Key Features

• 2 mm gaging diameter with 0.005 mm tolerance for precise go inspection
• 10 microfinish surface on gaging member reduces wear and improves measurement repeatability
• Tool steel construction provides hardness suited for repeated contact with workpiece bores
• Includes Certificate of Accuracy with NIST traceability for quality system compliance
• Meets ASME B89.1 standards for plain plug gages
• Suitable for setting micrometers, verniers, and other precision measuring devices

Compatibility

Designed for go inspection of 2 mm diameter bores and as a reference standard for setting micrometers, verniers, and other precision measuring devices. Conforms to ASME B89.1 dimensional and tolerance standards for plain cylindrical plug gages.

Installation Notes

Plug gages should be handled by metrology or quality technicians familiar with ASME B89.1 practices. Clean the gage and the bore being checked with a lint-free cloth before use to remove chips, coolant, or debris that could affect the reading or damage the gage surface. Do not force the gage into a bore — apply light, consistent hand pressure only. Store the gage in its protective case when not in use to prevent surface damage and maintain calibration integrity.
