Vermont Gage 111321650 Class Zz Plus Plug Gage 0.2165 in

Product Description

The VERMONT GAGE 111321650 is a Class ZZ Plus plug gage used to verify bore and hole diameters in a Go inspection workflow. Machined from tool steel to a 10 microfinish surface, it measures 0.2165 inches in diameter with a tolerance of 0.0002 inches. At 2.0 inches overall length, the gage is sized for handheld use in shop and field inspection. Each unit ships with a Certificate of Accuracy backed by NIST traceability, confirming conformance to ASME B89.1. Machinists, quality technicians, and tool room professionals rely on plug gages like this to confirm hole acceptance without requiring additional measurement setups.

This gage is suited for Go inspection of precision bores in manufacturing and quality control environments. It is also used to calibrate and verify the accuracy of set micrometers, verniers, and other measuring devices. Typical applications include incoming inspection, in-process quality checks, and toolroom calibration tasks across metalworking, aerospace, and general manufacturing settings.

Key Features

• Class ZZ Plus tolerance grade: 0.0002 inches, suitable for Go inspection applications
• 10 microfinish surface for consistent, low-wear contact during repeated use
• Tool steel construction provides durability and dimensional stability
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 dimensional standards
• Compact 2.0 inch overall length for easy handheld operation

Compatibility

Designed for Go inspection use and for setting or verifying set micrometers, verniers, and other precision measuring devices requiring a 0.2165 inch reference diameter.

Installation Notes

Plug gages are handled and applied by quality technicians or machinists in inspection environments, not installed in the field. Store the gage in its protective case when not in use to prevent surface damage or corrosion. Clean the gage and the bore being inspected before use to avoid false readings caused by debris or cutting fluid. Never force the gage into an undersized hole, as this can damage the gage surface and compromise calibration.
