Vermont Gage 112107180 Class Zz Plus Plug Gage 7.18mm

Product Description

The VERMONT GAGE 112107180 is a Class ZZ Plus cylindrical plug gage with a 7.18 mm diameter, manufactured from tool steel to ASME B89.1 standards. It is used to verify bore dimensions in machined parts and precision assemblies, serving as a go-inspection tool to confirm that a hole meets its minimum size requirement. The gage features a 10 microfinish surface and a tolerance of 0.005 mm, making it appropriate for applications that demand consistent, repeatable measurement results. Each unit ships with a Certificate of Accuracy backed by NIST traceability. Machinists, quality control technicians, and toolroom personnel are the primary users of this gage.

This plug gage is suited for go inspection tasks in manufacturing and metrology environments, including checking bored holes, drilled passages, and machined features in both production and inspection settings. It is compatible with use alongside set micrometers, verniers, and other precision measuring devices as noted in the manufacturer specifications. The 7.18 mm diameter makes it a direct fit for metric bore inspection at that nominal size. Overall length is 2.0 inches, keeping the tool compact for benchtop and inline inspection use.

Key Features

• Class ZZ Plus tolerance grade per ASME B89.1 for reliable go-inspection accuracy
• 7.18 mm diameter with 0.005 mm tolerance for precise bore verification
• Tool steel construction for wear resistance and dimensional stability
• 10 microfinish surface for smooth, repeatable gage entry
• Includes Certificate of Accuracy with NIST traceability
• Compact 2.0-inch overall length suitable for benchtop inspection use

Compatibility

Designed for go inspection of 7.18 mm diameter bores and for use with set micrometers, verniers, and other precision measuring devices per manufacturer application data.

Installation Notes

Plug gages are used by machinists and quality technicians and require no permanent installation. Before use, clean the gage and the bore being checked to remove chips, coolant, and debris that could affect the reading. Do not force the gage into an undersized bore, as this can damage the gage surface and invalidate the measurement. Store the gage in its case and handle it with care to preserve the calibrated finish and dimensional accuracy.
