Vermont Gage 111321750 Class Zz Plus Plug Gage 0.2175 in

Product Description

The VERMONT GAGE 111321750 is a Class ZZ Plus plug gage used to verify bore diameters and inside dimensions in go inspection applications. Machined from tool steel and finished to a 10 microfinish surface, this gage delivers a measurement diameter of 0.2175 inches with a tolerance of 0.0002 inches. At an overall length of 2.0 inches, it is sized for handheld use at the bench or on the shop floor. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming conformance to ASME B89.1 dimensional standards. Licensed machinists, quality technicians, and tool room personnel rely on this type of gage for fast, repeatable go/no-go verification.

This plug gage is suited for incoming inspection, in-process quality checks, and calibration verification of micrometers, verniers, and other measuring devices. It is appropriate for use in both production and tool room environments where precise bore qualification is required. The 0.2175-inch diameter targets small-bore applications common in precision machined components. The ASME B89.1 conformance makes it acceptable for use in shops operating under ISO or AS9100 quality management requirements.

Key Features

• Measurement diameter of 0.2175 inches for small-bore go inspection
• Tolerance of 0.0002 inches per Class ZZ Plus specification
• 10 microfinish surface for consistent, low-friction contact with bore surfaces
• Machined from tool steel for wear resistance and dimensional stability
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 dimensional gage standards

Compatibility

Designed for use as a go inspection gage and for setting or verifying micrometers, verniers, and other inside measuring devices requiring a 0.2175-inch reference diameter.

Installation Notes

Plug gages are handled and used by quality technicians and machinists and require no permanent installation. Store in a clean, dry environment away from temperature extremes to maintain dimensional accuracy. Clean the gage and the bore surface before use to prevent debris from affecting measurement results. Do not force the gage into an undersized bore, as this will damage the gage surface and compromise accuracy.
