Vermont Gage 111302150 Class Zz Plus Plug Gage 0.0215 in

Product Description

The VERMONT GAGE 111302150 is a Class ZZ Plus plug gage designed for precision dimensional inspection of small-diameter bores and holes. Manufactured from tool steel, this gage measures a nominal diameter of 0.0215 inches with a tolerance of 0.0002 inches, making it suitable for high-accuracy go inspection work. The 10 microfinish surface ensures consistent contact and reliable readings. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documentation requirements in quality-controlled environments. Metrology technicians and toolroom professionals use this gage as part of a complete dimensional verification workflow.

This plug gage is used in go inspection applications to verify that a hole or bore meets minimum size requirements. It is also compatible with setup and calibration of micrometers, verniers, and other precision measuring devices. The 2.0-inch overall length provides a practical handle section for controlled insertion without excessive hand contact that could affect readings through thermal expansion. Applicable in production, inspection, and toolroom environments where ASME B89.1 compliance is required.

Key Features

Compatibility

Designed for go inspection use and for setting micrometers, verniers, and other precision measuring devices requiring a 0.0215 inch reference diameter.

Installation Notes

Plug gages should be handled by qualified metrology or toolroom personnel following established inspection procedures. Clean the gage and the workpiece bore before use to prevent contamination from affecting measurements. Never force the gage into a bore; apply only light, consistent insertion pressure to avoid damage to the gage or workpiece. Store in a protective case away from temperature extremes to maintain dimensional stability.
