Vermont Gage 112307070 Class Zz Plus Plug Gage 7.07mm

Product Description

The VERMONT GAGE 112307070 is a Class ZZ Plus plug gage designed for precise internal diameter inspection in metrology and quality-control applications. Manufactured from tool steel with a 10 microfinish surface coating, this gage provides a nominal diameter of 7.07 mm with a tolerance of 0.00508 mm. The overall length is 2.0000 inches, making it a compact, hand-held instrument suited for bench inspection work. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting the documentation requirements of ASME B89.1. Machinists, quality technicians, and calibration professionals rely on this type of plug gage for fast, repeatable go-inspection checks of bored, drilled, or reamed features.

This plug gage is used in manufacturing inspection environments where bore size must be verified against a known standard. It is well suited for setting and verifying go-type inspection decisions on small-diameter holes in precision machined components. Compatible with standard gage-handle systems, it also serves as a reference for setting micrometers, verniers, and other variable measuring devices. Typical applications include incoming inspection, in-process quality checks, and final part acceptance in both job shop and production settings.

Key Features

• Class ZZ Plus tolerance grade — 0.00508 mm tolerance for reliable go-inspection decisions
• Tool steel construction for wear resistance and dimensional stability
• 10 microfinish surface coating for smooth gage entry and accurate contact
• Overall length of 2.0000 inches for easy handling at the bench
• Includes Certificate of Accuracy with NIST traceability per ASME B89.1
• Suitable for setting micrometers, verniers, and other measuring devices

Compatibility

Designed for use with standard plug gage handle systems accepting 7.07 mm diameter gage members. Suitable for go inspection of bored or reamed features at the 7.07 mm nominal diameter in precision machined parts.

Installation Notes

Plug gages should be handled and stored by calibration or quality personnel following shop metrology procedures. Clean the gage member and the bore being inspected before use to prevent debris from affecting the reading or causing premature wear. Do not force the gage into a bore; light hand pressure is sufficient for a go-type check. Store in the supplied case or a protected location away from heat sources and corrosive environments to maintain calibration integrity.
