Vermont Gage 112302210 Class Zz Plus Plug Gage 2.21mm

Product Description

The VERMONT GAGE 112302210 is a Class ZZ Plus plug gage used to verify bore and hole diameters in precision inspection applications. Manufactured from tool steel with a 10 microfinish surface coating, this gage measures a nominal diameter of 2.21 mm with a tolerance of 0.005 mm. It conforms to ASME B89.1 standards and ships with a Certificate of Accuracy traceable to NIST. Dimensional inspectors, quality technicians, and tool room professionals use plug gages like this one to confirm dimensional conformance on machined components before parts move to the next stage of production.

This plug gage is suited for go inspection tasks in manufacturing, tool and die, and metrology environments. It is compatible with use alongside micrometers, verniers, and other precision measuring devices as a reference or calibration check standard. Its compact overall length of 2.0 inches makes it easy to handle during bench inspection work. Typical applications include checking drilled, reamed, or bored holes in metal components where tight tolerances must be confirmed before assembly.

Key Features

• Class ZZ Plus tolerance grade at 0.005 mm for high-accuracy go inspection
• Tool steel construction for wear resistance and long service life
• 10 microfinish surface coating for smooth, repeatable gage contact
• Meets ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability for calibration documentation
• Compact 2.0-inch overall length for bench and in-process inspection use

Compatibility

Designed for use in go inspection of 2.21 mm diameter bores and holes. Compatible for use with micrometers, verniers, and other measuring devices as stated by the manufacturer.

Installation Notes

Plug gages are handled and used by quality technicians and metrology professionals, not installed in the field. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Clean the gage surface before each use with a lint-free cloth to ensure accurate contact. Do not force the gage into an undersized hole, as this will damage the gage surface and compromise accuracy.
