Vermont Gage 112114120 Class Zz Plus Plug Gage 14.12mm

Product Description

The VERMONT GAGE 112114120 is a Class ZZ Plus cylindrical plug gage designed for precise bore inspection in manufacturing and quality control environments. It measures 14.12 mm in diameter with a tolerance of 0.005 mm, making it suitable for go-inspection applications where tight dimensional verification is required. Manufactured from tool steel, it carries a 10 microfinish surface coating for consistent, repeatable contact with the bore surface. Overall length is 2.0 inches. Each unit ships with a Certificate of Accuracy with NIST traceability, confirming the gage meets ASME B89.1 standards. Quality control technicians and metrology professionals are the primary users of this instrument.

This plug gage is intended for go inspection of bored or reamed holes measuring 14.12 mm in diameter. It is also suited for setting and verifying micrometers, verniers, and other measuring devices in tool rooms, inspection labs, and on the shop floor. Its Class ZZ Plus classification places it within standard working-gage tolerances as defined by ASME B89.1, appropriate for both production inspection and calibration support tasks in precision machining environments.

Key Features

• 2.0 inch overall length suitable for standard gage handle systems

Compatibility

Designed for go inspection of 14.12 mm diameter bores and for use with micrometers, verniers, and other measuring devices as stated by the manufacturer. Compatible with standard plug gage handles appropriate for this diameter range.

Installation Notes

Plug gages are handled and used by quality control technicians and metrologists — no power tools or utility shutoffs are required for normal use. Store the gage in a protective case away from moisture and temperature extremes to preserve dimensional integrity. Clean the gage and bore surfaces before inspection to prevent debris from affecting readings. Do not force the gage into an undersized bore, as this can damage the gage surface finish and affect calibration.
