Vermont Gage 112102700 Class Zz Plus Plug Gage 2.7mm

Product Description

The VERMONT GAGE 112102700 is a Class ZZ Plus plug gage designed for precision dimensional inspection of small bores and holes with a nominal diameter of 2.70 mm. Manufactured from tool steel and finished to a 10 microfinish surface quality, this gage delivers reliable, repeatable measurement performance in shop and laboratory environments. A Certificate of Accuracy with NIST traceability is included, supporting quality management and calibration documentation requirements. Licensed metrology technicians, machinists, and quality control inspectors use this gage to verify workpiece hole dimensions to ASME B89.1 standards.

This plug gage is suited for go inspection applications where close-tolerance bore verification is required. It is also compatible with setup and calibration of micrometers, verniers, and other measuring devices requiring a traceable reference standard. The 2.70 mm diameter and 0.00508 mm tolerance make it appropriate for precision machining environments, toolrooms, and quality inspection stations handling small-diameter workpiece features.

Key Features

• Class ZZ Plus tolerance: 0.00508 mm for precise go inspection
• 2.70 mm nominal diameter for small-bore applications
• 10 microfinish surface quality for accurate, low-wear contact
• Tool steel construction for durability in production environments
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 dimensional gage standards

Compatibility

Suitable for go inspection of 2.70 mm diameter bores and holes, and for setting and verifying micrometers, verniers, and other hand measuring devices requiring a traceable plug reference.

Installation Notes

Plug gages are handled and used by metrology technicians, machinists, and quality inspectors — no power tools or mechanical installation is required. 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 an undersized bore, as this can damage both the gage and the workpiece. Store in the provided case or protective sleeve to maintain surface finish integrity and calibration validity.
