Vermont Gage 112103460 Class Zz Plus Plug Gage 3.46mm

Product Description

The VERMONT GAGE 112103460 is a Class ZZ Plus plug gage designed for precision dimensional inspection of hole diameters. Built from tool steel with a 10 microfinish surface, this gage checks a 3.46 mm nominal diameter with a tolerance of 0.00508 mm, making it suitable for go inspection work in manufacturing and quality control environments. Each unit ships with a Certificate of Accuracy that includes NIST traceability, confirming calibration to a recognized national standard. Metrology technicians, machinists, and quality inspectors use this type of gage as a fast, reliable method for pass/fail hole verification on the shop floor or in the inspection lab.

This plug gage is used in go inspection applications where hole diameter conformance must be confirmed quickly and accurately. It is also compatible with setting micrometers, verniers, and other measuring devices as a reference standard. The 2.0-inch overall length provides a comfortable grip for hand use in both production and bench inspection scenarios. Typical applications include incoming inspection, in-process quality checks, and final inspection across precision machining, tooling, and assembly operations.

• Includes Certificate of Accuracy with NIST traceability, meeting ASME B89.1 standards
• 2.0-inch overall length suited for hand-held use at production or inspection stations
• Compatible with setting micrometers, verniers, and other precision measuring instruments

Compatibility

Suitable for go inspection of 3.46 mm diameter holes and for setting micrometers, verniers, and other precision measuring devices per the manufacturer's stated application data.

Installation Notes

Plug gages of this type are handled and applied by metrology technicians or trained machinists. Clean the gage and the workpiece bore before use to prevent contamination that could affect readings. Store the gage in its case when not in use to protect the precision ground surface. Periodic re-calibration against a traceable standard is recommended to maintain measurement integrity over time.
