Vermont Gage 112109700 Class Zz Plus Plug Gage 9.7mm

Product Description

The VERMONT GAGE 112109700 is a Class ZZ Plus plug gage designed for dimensional inspection of bored holes and machined features. It checks that a hole meets minimum size requirements in go inspection workflows. Manufactured from tool steel with a 10 microfinish surface, it delivers consistent, reliable measurement performance in shop and quality-control environments. The gage measures a nominal diameter of 9.7 mm with a tolerance of 0.00508 mm, conforming to ASME B89.1 standards. Each unit ships with a Certificate of Accuracy backed by NIST traceability, satisfying documentation requirements for ISO and AS9100 quality systems. Overall length is 2 inches. Machinists, toolroom technicians, and quality inspectors are the primary users.

This plug gage is suited for go inspection of 9.7 mm diameter bores in production and job-shop settings. It is used with go inspection routines to verify that a hole is not undersized before assembly or further machining. It is also compatible as a setting standard for micrometers, verniers, and other measuring devices requiring a traceable reference. Applications span general machining, aerospace component inspection, hydraulic component manufacturing, and any precision work governed by tight bore tolerances.

Key Features

• Class ZZ Plus tolerance grade: 0.00508 mm tolerance for high-precision go inspection
• 10 microfinish surface on the gage pin for repeatable, low-wear contact
• Tool steel construction for hardness and dimensional stability under repeated use
• Conforms to ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability for quality system documentation
• Suitable as a setting standard for micrometers, verniers, and other measuring devices

Compatibility

Designed for go inspection of 9.7 mm diameter bores. Also functions as a setting reference for micrometers, verniers, and other measuring devices requiring a traceable dimensional standard.

Installation Notes

Plug gages are handled and used by machinists, toolroom technicians, and quality control inspectors — no power source or tool lockout is required. Clean the gage pin and bore thoroughly before use to prevent debris from affecting measurement readings. Store the gage in its protective case when not in use to preserve the surface finish and dimensional integrity. Avoid dropping or striking the gage pin, as impact damage will invalidate the stated tolerance and the Certificate of Accuracy.
