Vermont Gage 111347650 Class Zz Plus Plug Gage

Product Description

The VERMONT GAGE 111347650 is a Class ZZ Plus plug gage designed for dimensional inspection of bores, holes, and machined features. It measures 0.4765 inches in diameter with a tolerance of 0.0002 inches and a 10 microfinish surface. Built from tool steel, this plug gage delivers the accuracy and repeatability required for go inspection, setting micrometers, verniers, and other precision measuring devices. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for documented quality-control workflows. Manufactured to ASME B89.1 standards, it is a direct-use tool for machinists, quality technicians, and metrology professionals.

This plug gage is used in manufacturing, machine shops, and inspection environments where precise bore and hole diameter verification is required. It is suited for go inspection applications, confirming that a feature falls within the specified dimensional tolerance. The 0.4765-inch diameter and 2.0-inch overall length make it practical for use on small-to-medium bore features in both production and bench inspection settings.

Key Features

• Class ZZ Plus tolerance grade with 0.0002 inches dimensional tolerance for precise inspection
• 10 microfinish surface for consistent, low-friction gauge contact
• Tool steel construction for durability and wear resistance in production environments
• Manufactured to ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability for documentation-driven quality systems
• Compact 2.0-inch overall length for easy handling at the bench or on the floor

Compatibility

Designed for go inspection use with micrometers, verniers, and other precision measuring devices requiring a 0.4765-inch diameter reference standard.

Installation Notes

Plug gages are handled and used by machinists and quality control technicians; no installation in the traditional sense applies. Store the gage in its protective case when not in use and avoid dropping or striking it against hard surfaces, as impact can alter calibration. Clean the gage and the bore being inspected before use to prevent debris from affecting readings. Periodic recalibration against NIST-traceable standards is recommended to maintain measurement integrity.
