Vermont Gage 111321950 Class Zz Plus Plug Gage 0.2195 in

Product Description

The VERMONT GAGE 111321950 is a Class ZZ Plus plug gage designed for precision dimensional inspection of bores, holes, and cylindrical features. It measures 0.2195 inches in diameter with a tolerance of 0.0002 inches, making it suited for Go inspection tasks that require tight, reliable measurement verification. Constructed from tool steel, the gage features a 10 microfinish surface on the gaging member, which reduces wear and supports consistent contact with the workpiece. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Machinists, quality technicians, and tool room personnel use this gage in production and inspection environments.

This plug gage is used in applications where hole diameter must be verified to close tolerance. It is suited for Go inspection of drilled, reamed, or bored features at 0.2195 inches nominal. Compatible applications include setting micrometers, vernier calipers, and other comparative measuring devices. It is appropriate for use in both job shop and production inspection settings where ASME B89.1 compliance is required. The overall length of 2.0 inches provides a compact, handleable form factor for bench or in-process use.

• 10 microfinish surface finish on gaging member for consistent, low-wear contact
• Includes Certificate of Accuracy with NIST traceability
• Meets ASME B89.1 dimensional standards
• Compact 2.0 inch overall length suitable for bench inspection and in-process checks

Compatibility

Designed for Go inspection of 0.2195 inch diameter bores and holes. Also suited for setting micrometers, verniers, and other measuring devices requiring a traceable reference standard per ASME B89.1.

Installation Notes

Plug gages are installed and used by quality technicians and machinists in inspection or tool room environments. Clean the gage and the part bore thoroughly before use to prevent debris from affecting measurement accuracy. Do not force the gage into the bore; apply only light, controlled hand pressure. Store the gage in a protective case and avoid contact with abrasive surfaces to preserve the microfinish and dimensional integrity.
