Vermont Gage 111167900 Class Zz Plus Plug Gage 0.679 in

Product Description

The VERMONT GAGE 111167900 is a Class ZZ Plus plug gage designed for precision dimensional inspection of bores, holes, and internal features. Manufactured from tool steel with a 10 microfinish surface finish, this gage measures at a nominal diameter of 0.679 inches with a tolerance of 0.0002 inches. It ships with a Certificate of Accuracy traceable to NIST, making it suitable for quality-controlled production and inspection environments. Metrology technicians, machinists, and quality control professionals use this gage to verify conformance to tight dimensional tolerances in manufactured parts. Its overall length of 2.0 inches provides adequate handling clearance for most standard inspection setups.

This plug gage is intended for go inspection applications, confirming that a bore or hole is at or above the minimum acceptable diameter. It is also used to calibrate and set measuring instruments such as micrometers, verniers, and other comparative measuring devices. Suitable for both shop-floor inspection and laboratory metrology, this gage meets ASME B89.1 standards for gage dimensional accuracy. Typical users include machine shops, quality labs, and manufacturing facilities requiring traceable, repeatable go-style inspection of close-tolerance bores.

Key Features

• Class ZZ Plus tolerance grade with 0.0002 inches tolerance for close-tolerance go inspection
• 10 microfinish surface finish for accurate, consistent contact with bore surfaces
• Tool steel construction for durability and dimensional stability in shop environments
• Meets ASME B89.1 standards for dimensional gaging accuracy
• Includes Certificate of Accuracy with NIST traceability for documentation and calibration records
• Compatible with set micrometers, verniers, and other comparative measuring devices

Compatibility

Designed for go inspection of bores and holes at 0.679 inches nominal diameter, and for setting micrometers, verniers, and other measuring devices requiring a traceable reference standard. Conforms to ASME B89.1 dimensional requirements.

Installation Notes

Handle plug gages carefully to avoid surface contamination or damage that could affect measurement accuracy. Clean the gage and the bore with a lint-free cloth before use. Never force a go gage through an undersized bore. Store in a protective case away from heat sources and corrosive environments to maintain calibration integrity.
