Vermont Gage 111316750 Class Zz Plus Plug Gage 0.1675 in

Product Description

The VERMONT GAGE 111316750 is a Class ZZ Plus plug gage machined from tool steel for dimensional go inspection of bore and hole features. It measures a nominal diameter of 0.1675 inches with a tolerance of 0.0002 inches, and carries a 10 microfinish surface finish on the gage member. The overall length is 2.0 inches. A Certificate of Accuracy with NIST traceability is included, confirming conformance to ASME B89.1 standards. Machinists, quality technicians, and metrology personnel use this gage to verify that a bored or drilled feature accepts the nominal dimension within tolerance.

This plug gage is suited for go inspection in manufacturing, tool room, and quality control environments. It is used alongside set micrometers, verniers, and other precision measuring devices to verify hole size acceptance in production or incoming inspection workflows. The Class ZZ Plus designation indicates a tighter tolerance class appropriate for inspection of precision-machined components in both job shop and high-volume production settings. The included NIST-traceable certificate supports use in quality management systems requiring documented calibration records.

Key Features

• 0.0002 inch tolerance per Class ZZ Plus classification
• 10 microfinish surface finish on gage member for consistent contact and accurate readings
• Manufactured from tool steel for hardness and wear resistance
• Conforms to ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability for quality documentation

Compatibility

Designed for use as a go plug gage in bore and hole inspection applications; compatible with standard gage handle sets and suitable for use with set micrometers, verniers, and other precision measuring devices as stated by the manufacturer.

Installation Notes

Plug gages should be handled and stored in accordance with ASME B89.1 care guidelines to prevent damage to the gage surface or alteration of calibration. Clean the gage and the workpiece bore before use to remove chips, coolant, and debris that could affect the measurement. Do not force the gage member into the bore; a go gage should enter freely under its own weight or light hand pressure. Periodic recalibration by a qualified metrology technician is recommended to maintain NIST-traceable accuracy.
