Vermont Gage 111133900 Class Zz Plus Plug Gage 0.339 in

Product Description

The VERMONT GAGE 111133900 is a Class ZZ Plus plug gage machined from tool steel for precise dimensional inspection work. With a measurement diameter of 0.339 inches and a tolerance of 0.0002 inches, this gage delivers tight, reliable results in go inspection applications. The working surface carries a 10 microfinish rating, reducing wear on the part being checked and maintaining consistent contact geometry over repeated use. Each unit ships with a Certificate of Accuracy backed by NIST traceability, confirming conformance to ASME B89.1 standards. Machinists, quality technicians, and metrology personnel use this tool to verify bore and hole dimensions in production and inspection environments.

This plug gage is suited for go inspection tasks in both shop-floor and inspection-room settings. It is commonly used alongside set micrometers, verniers, and other measuring devices to confirm dimensional acceptance of drilled, reamed, or bored features. The 0.339-inch diameter makes it appropriate for precision hole verification in small-to-medium machined components. The 2.0-inch overall length provides comfortable handling during single-hand operation. This gage is appropriate for quality control professionals, toolroom technicians, and anyone performing dimensional verification to ASME standards.

Key Features

• Measurement diameter of 0.339 inches with a tolerance of 0.0002 inches for precise go inspection
• 10 microfinish surface finish minimizes wear on inspected bores and maintains gage accuracy over time
• Constructed from tool steel for durability in production and inspection environments
• Conforms to ASME B89.1 dimensional gage standards
• Includes a Certificate of Accuracy with NIST traceability for calibration documentation requirements
• 2.0-inch overall length for stable single-hand operation

Compatibility

Designed for go inspection use with set micrometers, verniers, and other precision measuring devices where a 0.339-inch diameter reference gage is required per ASME B89.1.

Installation Notes

Plug gages are handled and used by quality technicians and metrology personnel; no mechanical installation is required. Store the gage in its protective case when not in use and avoid dropping or striking the working surface, as impact can alter the calibrated diameter. Clean the gage and the bore to be checked before use to prevent debris from affecting measurement results. Re-verify gage calibration periodically according to your facility quality management procedures.
