Vermont Gage 111128600 Class Zz Plus Plug Gage 0.286 in

Product Description

The VERMONT GAGE 111128600 is a Class ZZ Plus plug gage designed for go inspection of bored, drilled, and reamed holes. It measures a nominal diameter of 0.286 inches with a tolerance of 0.0002 inches, delivering the dimensional accuracy required for production floor and quality lab use. Manufactured from tool steel and finished to a 10 microfinish surface, this gage provides consistent, repeatable results across high-cycle inspection tasks. Each unit ships with a Certificate of Accuracy that includes NIST traceability, meeting the documentation requirements for ISO and AS9100 quality systems. Machinists, quality technicians, and metrology professionals install and use this gage in both shop-floor and inspection room environments.

This plug gage is suited for go-side dimensional verification on workpieces where hole size conformance must be confirmed before assembly or further machining. Typical applications include setting and verifying micrometers, verniers, and other measuring devices, as well as direct hole inspection in metal fabrication, aerospace, automotive, and general manufacturing settings. It is appropriate for use in both job shop and high-volume production environments where ASME B89.1 compliance is required.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for precise go inspection
• 10 microfinish surface for consistent gage-to-workpiece contact
• Tool steel construction for durability in production environments
• Includes Certificate of Accuracy with NIST traceability
• Compliant with ASME B89.1 dimensional gage standards
• 2.0-inch overall length for easy handling in standard gage fixtures

Compatibility

Designed as an OEM-style go plug gage for use with standard gage handles and setting fixtures suited to 0.286-inch nominal diameter applications in compliance with ASME B89.1.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no permanent installation is required. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Do not force the gage into an undersized hole, as this can damage the gage land and compromise measurement accuracy. Store in the provided case or a protective sleeve away from abrasive materials and temperature extremes.
