Vermont Gage 111319450 Class Zz Plus Plug Gage 0.1945 in

Product Description

The VERMONT GAGE 111319450 is a Class ZZ Plus plug gage used to perform go inspection on machined bores and holes. Manufactured from tool steel with a 10 microfinish surface, it measures an exact diameter of 0.1945 inches with a tolerance of 0.0002 inches. The overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy that carries NIST traceability, supporting documented quality control processes. This gage is designed for machinists, tool and die makers, and quality technicians who need reliable, repeatable dimensional verification in a production or inspection environment.

This plug gage is used for go inspection of holes and bores where the nominal diameter is 0.1945 inches. It is well suited for checking workpieces machined to tight tolerances in precision manufacturing settings. Compatible with standard gage handle holders, it can also be used alongside set micrometers, verniers, and other calibrated measuring devices to verify or reference dimensional accuracy on production runs and incoming inspection workflows.

Key Features

• Class ZZ Plus tolerance class — 0.0002 inch tolerance for precision go inspection
• Tool steel construction provides durability and wear resistance in regular production use
• 10 microfinish surface for consistent, accurate seating in the measured bore
• NIST-traceable Certificate of Accuracy included for quality documentation and audit compliance
• Meets ASME B89.1 standard for plain plug gages
• Overall length of 2.0000 inches fits standard gage handle configurations

Compatibility

Designed for go inspection use with set micrometers, verniers, and other measuring devices requiring a 0.1945 inch reference diameter. Fits standard commercial gage handles sized for this diameter class.

Installation Notes

Plug gages should be handled and stored carefully to prevent damage to the precision ground surface. Clean the gage and the workpiece bore before use to remove chips, oil, or debris that could affect measurement accuracy. Never force a go gage through a bore — if the gage does not pass with light hand pressure, the hole is undersize and should be reworked. Periodic recalibration against NIST-traceable standards is recommended to maintain measurement integrity.
