Vermont Gage 112314370 Class Zz Plus Plug Gage 14.37mm

Product Description

The VERMONT GAGE 112314370 is a Class ZZ Plus plug gage machined from tool steel and used to verify bore diameters in precision inspection workflows. Rated to a tolerance of 0.005 mm (0.00508 mm actual), it is designed for Go inspection applications where confirming a minimum acceptable hole size is required. The 10 Micro coating finish protects the gauge surface and supports consistent, repeatable readings over extended use. Weighing 0.15 pounds and measuring 2.0000 inches in overall length, this gage is a compact and durable addition to any calibrated inspection station. Each unit ships with a Certificate of Accuracy with NIST Traceability, meeting ASME B89.1 standards.

This plug gage is suited for use in quality control environments where bore diameters must be confirmed against tight tolerances. It is compatible with Go inspection routines and is commonly used alongside set micrometers, verniers, and other precision measuring devices. Typical users include metrology technicians, toolroom machinists, and quality assurance professionals working in manufacturing, aerospace, automotive, and general industrial settings. The 14.37 mm diameter targets a specific bore size within the mid-range metric spectrum.

Compatibility

Designed for use in Go inspection applications and compatible with set micrometers, verniers, and other precision measuring devices as noted in manufacturer specifications.

Installation Notes

Plug gages are handled and used by metrology technicians and toolroom personnel — they are not installed in the traditional sense but must be stored and used correctly to maintain calibration integrity. Always clean the gage and the bore being inspected before use to prevent debris from affecting readings. Do not force the gage into an undersized bore, as this can damage both the gage and the workpiece. Store in a protective case away from moisture and temperature extremes to preserve NIST-traceable accuracy.
