Vermont Gage 112316550 Class Zz Plus Plug Gage 16.55mm

Product Description

The VERMONT GAGE 112316550 is a Class ZZ Plus plug gage machined from tool steel and finished to a 10 micro-inch surface coating. It measures 16.55 mm in diameter with a tolerance of 0.00508 mm, making it suited for precise go-inspection work in quality-control environments. The overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documentation requirements in calibrated metrology programs. Licensed metrologists, quality technicians, and precision machinists are the primary users of this gage.

This plug gage is used for go inspection of bored holes, drilled passages, and machined features that must conform to tight dimensional tolerances. It is also applied when setting micrometers, verniers, and other measuring devices to a known reference diameter. Typical environments include machine shops, aerospace assembly lines, medical device manufacturing, and any production setting governed by ASME B89.1 standards. The 16.55 mm diameter positions this gage in the range commonly encountered in metric mechanical assemblies requiring repeatable attribute inspection.

Key Features

• Class ZZ Plus tolerance grade for go-inspection applications per ASME B89.1
• 16.55 mm diameter with 0.00508 mm tolerance for precise attribute checking
• Tool steel construction with 10 micro-inch surface finish for wear resistance and dimensional stability
• Includes Certificate of Accuracy with NIST traceability to support calibration records
• Overall length of 2.0000 inches fits standard plug gage handles and tri-lock style holders

Compatibility

Designed for use as a go plug gage member in standard plug gage handle assemblies compatible with 16.55 mm diameter gage blanks, and suitable for setting micrometers, verniers, and other measuring devices requiring a traceable reference diameter.

Installation Notes

Plug gages are handled and stored by metrology or quality-control personnel, not installed in the field sense. Clean the gage and the workpiece bore before use to prevent contamination from affecting the measurement. Never force the gage into a feature; damage to the gage or workpiece can result. Store the gage in its protective case when not in use to prevent corrosion and surface damage to the lapped faces.
