Vermont Gage 111320550 Class Zz Plus Plug Gage 0.2055 in

Product Description

The VERMONT GAGE 111320550 is a Class ZZ Plus plug gage manufactured from tool steel for dimensional go inspection of holes and bores. It measures a nominal diameter of 0.2055 inches with a tolerance of 0.0002 inches and features a 10 microfinish surface for consistent, repeatable contact. The overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming conformance to ASME B89.1 standards. This gage is used by machinists, quality technicians, and toolroom professionals who require reliable attribute inspection of precision-machined features.

This plug gage is suited for go inspection applications in manufacturing and quality control environments. It is compatible with use alongside set micrometers, verniers, and other measuring devices where a traceable reference is required. Typical applications include verifying drilled, reamed, or bored hole diameters in close-tolerance production work, incoming inspection, and first-article verification. Its compact 2.0000-inch overall length allows access to shallow bores and blind holes in standard workpiece configurations.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for precision go inspection
• 10 microfinish surface provides consistent gauge contact and reduces wear
• Tool steel construction for hardness and dimensional stability
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 dimensional standards
• Overall length of 2.0000 inches for access to standard bore depths

Compatibility

Designed for go inspection use with set micrometers, verniers, and other precision measuring devices as an OEM-style reference gage for hole and bore diameter verification in close-tolerance machining applications.

Installation Notes

Plug gages are handled and applied by quality technicians and machinists in inspection and toolroom settings. Clean both the gage and workpiece bore before use to prevent contamination errors. Store the gage in its protective case when not in use to preserve the ground surface finish and dimensional integrity. Do not force the gage into an undersized bore, as this will damage the gage surface and invalidate calibration.
