Vermont Gage 112100220 Class Zz Plus Plug Gage 0.22mm

Product Description

The VERMONT GAGE 112100220 is a Class ZZ Plus plug gage designed for precision inspection of small bores and holes at 0.22 mm diameter. Manufactured from tool steel with a 10 microfinish surface coating, this gage delivers a tolerance of 0.00508 mm, making it suitable for go inspection applications where tight dimensional verification is required. It ships with a Certificate of Accuracy with NIST Traceability, confirming its conformance to ASME B89.1 standards. Licensed metrology technicians, quality control inspectors, and tool-and-die professionals rely on plug gages of this class for repeatable, documentable measurement results in production and inspection environments.

This plug gage is used in go inspection routines to verify that a drilled, reamed, or bored hole meets minimum size requirements. At 0.22 mm, it is suited for applications involving very small-diameter features such as precision orifices, micro-bored components, and fine-tolerance assemblies. It is also referenced alongside set micrometers, verniers, and other calibrated measuring devices during setup and verification procedures in both shop-floor and laboratory settings.

Key Features

• Class ZZ Plus tolerance grade at 0.00508 mm for precise go inspection
• Tool steel construction for wear resistance and dimensional stability
• 10 microfinish surface coating reduces friction and protects gage integrity
• Includes Certificate of Accuracy with NIST Traceability
• Conforms to ASME B89.1 dimensional gage standards
• Compatible with set micrometers, verniers, and other calibrated measuring devices

Compatibility

Designed for use in go inspection routines and as a reference standard alongside set micrometers, verniers, and other calibrated measuring devices per ASME B89.1 requirements.

Installation Notes

Plug gages of this class are handled and used by quality control technicians and metrologists. 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 a bore; apply only light, consistent hand pressure during inspection to avoid wear or deflection at this diameter. Store in its case away from temperature extremes to maintain dimensional accuracy between calibrations.
