Vermont Gage 112301010 Class Zz Plus Plug Gage 1.01mm

Product Description

The VERMONT GAGE 112301010 is a Class ZZ Plus plug gage designed for precise go inspection of small bores and holes. It measures 1.01 mm in diameter with a tolerance of 0.00508 mm, making it suited for high-accuracy dimensional verification in production and quality-control environments. The gage is machined from tool steel and features a 10 microfinish surface on the gaging member. Overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy with NIST traceability, meeting ASME B89.1 standards. Machinists, metrologists, and quality technicians use this gage to verify bore dimensions against specified tolerances.

This plug gage is used in go inspection applications where a bore or hole must be confirmed to be at or above its minimum acceptable size. Typical uses include verifying machined holes, setting micrometers, and calibrating verniers and other measuring devices. It is appropriate for light-industrial and precision-manufacturing environments where sub-millimeter bore accuracy is required. The small 1.01 mm diameter makes it applicable to fine-bore inspection tasks that larger gages cannot reach.

Key Features

• Class ZZ Plus tolerance grade with 0.00508 mm tolerance for high-accuracy go inspection
• 1.01 mm gage diameter for fine-bore and small-hole applications
• Tool steel construction for wear resistance and dimensional stability
• 10 microfinish surface on the gaging member for consistent contact
• Overall length of 2.0000 inches for easy handling and integration with standard handle sets
• Includes Certificate of Accuracy with NIST traceability, conforming to ASME B89.1

Compatibility

Designed for use as a go plug gage in standard go inspection setups and for setting micrometers, verniers, and other measuring devices requiring a 1.01 mm reference diameter.

Installation Notes

Plug gages are handled and used by machinists and quality-control technicians; no power source or shutoff is required. Store the gage in its protective case when not in use to prevent corrosion and surface damage. Apply a light film of oil to the gage surface during storage to preserve the finish. Do not force the gage through a bore; interference indicates the bore is undersized.
