Vermont Gage 112314310 Class Zz Plus Plug Gage 14.31mm

Product Description

The VERMONT GAGE 112314310 is a Class ZZ Plus plug gage designed for precision diameter inspection of bores and holes measuring 14.31 mm. Built from tool steel with a 10 microfinish surface coating, it delivers reliable, repeatable measurements in quality-control and metrology environments. The gage holds a tolerance of 0.00508 mm, making it suitable for demanding inspection work where tight dimensional control is required. Every unit ships with a Certificate of Accuracy traceable to NIST, supporting audit and calibration documentation requirements. It conforms to ASME B89.1 standards. Licensed metrology technicians, machinists, and quality-control inspectors are the primary users of this tool.

This plug gage is used in shop-floor and laboratory inspection settings to verify bore diameter conformance during manufacturing and incoming-parts inspection. It is suited for go-type inspection applications and can also be used to set and verify micrometers, verniers, and other measuring devices. Typical install scenarios include inline QC checks on machined components, tool and die verification, and calibration reference work in both production and metrology lab environments.

Key Features

• Class ZZ Plus tolerance: 0.00508 mm for tight dimensional control
• 10 microfinish surface coating for smooth, repeatable gage contact
• Tool steel construction for durability and wear resistance
• Conforms to ASME B89.1 standards
• Includes Certificate of Accuracy with NIST traceability
• Suitable for go inspection and as a reference standard for calibrating measuring devices

Compatibility

Designed for use as a go plug gage for 14.31 mm diameter bores and as a setting standard for micrometers, verniers, and other precision measuring devices in accordance with ASME B89.1.

Installation Notes

Plug gages are handled and used by metrology technicians and quality-control personnel. Store the gage in its protective case when not in use to prevent corrosion and damage to the finished surface. Clean the gage and the bore being inspected before use to avoid false readings caused by debris or coolant residue. Do not force the gage into an undersized bore, as this will cause wear and compromise calibration accuracy.
