Vermont Gage 111161000 Class Zz Plus Plug Gage 0.61 in

Product Description

The VERMONT GAGE 111161000 is a Class ZZ Plus plug gage designed for precision dimensional inspection of holes and bores. Manufactured from tool steel, this go-style gage measures a nominal diameter of 0.61 inches with a tolerance of 0.0002 inches, making it suitable for high-accuracy inspection work. The working surface carries a 10 microfinish surface finish for consistent, repeatable contact. Each unit ships with a Certificate of Accuracy that includes NIST traceability, meeting the documentation requirements common in quality-controlled manufacturing and metrology environments. Machinists, quality technicians, and metrologists are the primary users of this type of precision tooling.

This plug gage is used in go inspection applications to verify that a hole or bore meets its minimum acceptable size. It is also suited for setting and calibrating micrometers, verniers, and other measuring devices that require a known reference standard. The 0.61-inch diameter and overall length of 2 inches make it a practical bench tool in machine shops, toolrooms, and quality assurance labs handling close-tolerance work in both production and maintenance settings. Compliance with ASME B89.1 ensures the gage meets recognized dimensional standards for gage accuracy and performance.

Key Features

• 0.61-inch nominal measurement diameter with 0.0002-inch tolerance for tight go-inspection work
• Class ZZ Plus classification per ASME B89.1 dimensional standards
• Tool steel construction for wear resistance and dimensional stability
• 10 microfinish surface finish for consistent gage contact
• Includes Certificate of Accuracy with NIST traceability for documentation and calibration records
• Suitable for setting micrometers, verniers, and other precision measuring instruments

Compatibility

Designed for go inspection of holes and bores at 0.61 inches nominal diameter, and for use as a reference standard when setting micrometers, verniers, and other measuring devices.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no power source is required. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surfaces. Do not force the gage into a bore, as this can damage both the gage and the workpiece. Store in a protective case away from temperature extremes to maintain dimensional stability.
