Vermont Gage 111107000 Class Zz Plus Plug Gage 0.07 in

Product Description

The VERMONT GAGE 111107000 is a Class ZZ Plus plug gage manufactured from tool steel, designed for precise go inspection of small bores and holes at a nominal diameter of 0.07 inches. It carries a tolerance of 0.0002 inches and a 10 microfinish surface finish, making it suitable for high-accuracy dimensional verification in production and quality-control environments. At 2.0 inches overall length, it fits standard gage handle setups. Each unit ships with a Certificate of Accuracy that includes NIST traceability, confirming the gage meets ASME B89.1 standards. Machinists, quality technicians, and toolroom professionals use this gage for fast, reliable go inspection checks.

This plug gage is intended for go inspection of precision-machined bores, drilled holes, and other internal features at the 0.07-inch diameter range. It is also suited for setting and verifying micrometers, verniers, and other measuring devices requiring a traceable reference standard. Typical applications include production floor inspection, incoming quality checks, and toolroom calibration work in both light manufacturing and precision machining environments. The Class ZZ Plus designation meets commercial-grade tolerance requirements as defined under ASME B89.1.

Key Features

• Nominal measurement diameter of 0.07 inches for small-bore go inspection
• Tolerance of 0.0002 inches per ASME B89.1 Class ZZ Plus specification
• 10 microfinish surface finish for consistent, low-friction gage entry
• Tool steel construction for hardness and wear resistance in production use
• Includes Certificate of Accuracy with NIST traceability
• Compatible with standard gage handle setups at 2.0 inches overall length

Compatibility

Designed for use with standard plug gage handles accepting small-diameter gage members. Also suitable for setting micrometers, verniers, and other measuring devices requiring a certified dimensional reference at 0.07 inches.

Installation Notes

This gage is handled and used by quality technicians and toolroom machinists — no power tools or utilities need to be shut down prior to use. Store the gage in its protective case when not in use to prevent corrosion and surface damage on the tool steel finish. Apply a light coat of instrument oil periodically to protect against rust. Always clean the gage and the workpiece bore before inspection to avoid false readings from chips or contamination.
