Vermont Gage 112316850 Class Zz Plus Plug Gage 16.85mm

Product Description

The VERMONT GAGE 112316850 is a Class ZZ Plus plug gage machined from tool steel and used to verify bore diameters to tight dimensional tolerances. It carries a diameter of 16.85 mm with a tolerance of 0.00508 mm, making it suitable for go inspection tasks where precise, repeatable measurement is required. The overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy with NIST traceability, confirming the gage has been verified against national measurement standards. Machinists, quality technicians, and metrology professionals use plug gages like this one to confirm that bored or reamed holes fall within specified limits before parts advance through production.

This plug gage is suited for go inspection applications in manufacturing and quality control environments. It is used alongside micrometers, verniers, and other measuring devices to check bore conformance on precision-machined components. The 16.85 mm diameter covers a common metric bore size found in both production and toolroom settings. Residential or light commercial machine shops, aerospace, and general metalworking facilities all rely on Class ZZ Plus gages for process control and incoming inspection. The included NIST-traceable certificate supports documentation requirements for ISO- and AS9100-regulated quality systems.

Key Features

• 2.0000 inch overall length for standard plug gage handling
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 standards

Compatibility

Designed for use with go inspection setups and compatible with micrometers, verniers, and other measuring devices as stated by the manufacturer. Suitable for any application requiring Class ZZ Plus plug gage verification at 16.85 mm bore diameter.

Installation Notes

Plug gages are handled and used by quality technicians and machinists and require no permanent installation. Store the gage in its protective case when not in use to prevent nicks or surface damage that would affect accuracy. Clean the gage and the bore being checked before use to remove chips, oil, or debris that can introduce measurement error. Do not force the gage into an undersized bore, as this can damage the gage surface and compromise NIST-traceable calibration status.
