Vermont Gage 112322490 Class Zz Plus Plug Gage 22.49 Mm

Product Description

The VERMONT GAGE 112322490 is a Class ZZ Plus plug gage designed for precise dimensional inspection of bored holes and machined features. It measures 22.49 mm in diameter with a tolerance of 0.005 mm (0.00508 mm), making it suitable for go inspection applications where part acceptance depends on confirming a minimum bore size. The gage is machined from tool steel and features a 10 micro finish coating. Overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy traceable to NIST standards, supporting quality documentation requirements. Metrology technicians, toolroom machinists, and quality control inspectors are the primary users of this type of gage.

This plug gage is used in manufacturing inspection environments to verify that bored, drilled, or reamed holes meet minimum diameter specifications. It is suited for use alongside set micrometers, verniers, and other measuring devices as part of a go/no-go inspection routine. Class ZZ Plus gages are commonly used in toolrooms and production QC stations where hole size verification is performed to ASME B89.1 standards. Applicable to both light-production and toolroom inspection settings.

Compatibility

Designed for use in go inspection applications and compatible with set micrometers, verniers, and other measuring devices as stated by the manufacturer. Suitable for any inspection setup requiring a Class ZZ Plus plug gage at 22.49 mm diameter per ASME B89.1.

Installation Notes

Plug gages are handled and used by metrology technicians and quality control inspectors in toolroom or production environments. Always ensure the gage and the workpiece bore are clean and free of chips or contaminants before use to prevent false readings or gage damage. Do not force the gage into a bore; apply light, consistent hand pressure only. Store the gage in its case when not in use to protect the finish and maintain dimensional accuracy.
