Vermont Gage 112302170 Class Zz Plus Plug Gage 2.17mm

Product Description

The VERMONT GAGE 112302170 is a Class ZZ Plus plug gage designed for precise dimensional inspection of small bored holes and machined features. Manufactured from tool steel, this gage measures 2.17 mm in diameter with a tolerance of 0.005 mm, making it suited for tight-tolerance go inspection work. The 10 microfinish surface ensures repeatable contact and minimal wear during routine use. Each unit ships with a Certificate of Accuracy that carries NIST traceability, meeting the documentation requirements common in quality-controlled manufacturing environments. Conforms to ASME B89.1 standards.

This plug gage is used in go inspection applications to verify that a hole or bore meets its minimum size requirement. Typical users include machinists, quality control technicians, and metrology lab personnel working in precision manufacturing, aerospace, medical device, and general metalworking environments. It is also suitable for setting and verifying micrometers, verniers, and other measuring devices where a known reference diameter is needed. The small 2.17 mm diameter makes it appropriate for fine bores and close-tolerance work where larger gages are impractical.

Key Features

• Class ZZ Plus tolerance grade — 0.005 mm tolerance for precise go inspection
• Tool steel construction for durability and dimensional stability
• 10 microfinish surface for consistent, repeatable gage contact
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 dimensional gage standards
• Compatible with go inspection setups, micrometers, verniers, and other measuring devices

Compatibility

Designed for go inspection use with micrometers, verniers, and other measuring devices requiring a 2.17 mm reference diameter. Suitable as a go gage in any inspection setup governed by ASME B89.1.

Installation Notes

Handle plug gages with clean, dry hands or lint-free gloves to prevent corrosion from skin contact. Store in the protective case or sleeve when not in use to preserve the surface finish and dimensional accuracy. Apply a light film of gage oil during storage to prevent rust on the tool steel body. Inspection and calibration should be performed by qualified metrology or quality control personnel in accordance with applicable shop standards.
