Vermont Gage 112100800 Class Zz Plus Plug Gage 0.8mm

Product Description

The VERMONT GAGE 112100800 is a Class ZZ Plus plug gage machined from tool steel and finished to a 10 microfinish surface. It measures 0.8 mm in diameter with a tolerance of 0.00508 mm, making it suitable for precise go inspection work in metrology and quality control environments. The overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting the documentation requirements common in ISO-registered and aerospace shops. Machinists, quality technicians, and tool room professionals use this gage to verify bore and hole dimensions against tight tolerance specifications.

This plug gage is designed for go inspection of small-diameter bores and holes where tight dimensional control is required. It is also used to set and verify micrometers, verniers, and other measuring devices in calibration and inspection workflows. Typical applications include production quality checks, incoming inspection, and instrument calibration in machine shops, manufacturing facilities, and metrology labs. The small 0.8 mm diameter makes it appropriate for miniature or precision-machined components found in medical device, electronics, and aerospace production environments.

Key Features

• 0.8 mm diameter with 0.00508 mm tolerance for precise go inspection

• 2.0000 inch overall length for comfortable handling and gage block integration
• Includes Certificate of Accuracy with NIST traceability for documentation compliance
• Conforms to ASME B89.1 standards

Compatibility

Designed for use in go inspection of 0.8 mm diameter bores and as a setting standard for micrometers, verniers, and other measuring devices requiring a traceable reference.

Installation Notes

Plug gages are handled and used by quality technicians and machinists familiar with precision metrology practices. Clean the gage and the bore thoroughly before use to prevent contamination from affecting measurement accuracy. Store the gage in its protective case when not in use to prevent damage to the ground surface. Do not force the gage into an undersized bore, as this can damage both the gage and the workpiece.
