Vermont Gage 111171600 Class Zz Plus Plug Gage 0.716 in

Product Description

The VERMONT GAGE 111171600 is a Class ZZ Plus plug gage designed for precision dimensional inspection of bores, holes, and internal features. Manufactured from tool steel, this gage measures a nominal diameter of 0.716 inches with a tolerance of 0.0002 inches, delivering the close-tolerance accuracy required for go inspection work. The 10 microfinish surface provides consistent, repeatable contact. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for use in calibration and quality-control environments. Metrology technicians, machinists, and quality assurance personnel rely on plug gages of this class for verifying hole size compliance to drawing tolerances.

This plug gage is suited for go inspection of drilled, reamed, or bored holes in manufacturing and machine shop environments. It is also used to set and verify micrometers, verniers, and other measuring devices requiring a known reference standard. The 2.0-inch overall length provides adequate handle for access in typical part features. Applications span general metalworking, toolroom work, and quality lab use where ASME B89.1 conformance is required.

Key Features

• 0.716 inch nominal measurement diameter for precise go inspection
• Class ZZ Plus tolerance of 0.0002 inches per ASME B89.1
• 10 microfinish surface for consistent gage contact and wear resistance
• Tool steel construction for durability in production and lab environments
• Includes Certificate of Accuracy with NIST traceability
• Suitable for setting micrometers, verniers, and other measuring devices

Compatibility

Designed for go inspection of internal features and as a reference standard for setting micrometers, verniers, and comparable measuring devices where a 0.716 inch diameter reference is required.

Installation Notes

Plug gages are handled and used by metrology technicians and quality control personnel. Store the gage in its case when not in use to prevent corrosion and surface damage. Wipe contact surfaces clean before each use and apply a light coat of instrument oil for storage. Do not force the gage into a feature; excessive insertion force will accelerate wear and compromise accuracy.
