Vermont Gage 112115000 Class Zz Plus Plug Gage 15 Mm

Product Description

The VERMONT GAGE 112115000 is a Class ZZ Plus plug gage designed for go inspection of 15 mm diameter bores and holes. Machined from tool steel and finished to a 10 microfinish surface, it delivers the dimensional consistency required for reliable attribute inspection in production and quality-control environments. The gage carries a tolerance of 0.00508 mm and includes a Certificate of Accuracy with NIST traceability, meeting ASME B89.1 standards. Metrology technicians, machinists, and quality inspectors use this type of gage to verify that a workpiece bore falls within the acceptable lower limit of its tolerance band.

This plug gage is suited for go inspection applications in manufacturing, toolroom, and quality lab settings. It is compatible with standard gage handle systems and is commonly used alongside set micrometers, verniers, and other precision measuring devices to confirm dimensional compliance on machined components. Its 2.0 inch overall length fits standard gage handles used across light manufacturing and precision machining operations.

Key Features

• Class ZZ Plus tolerance of 0.00508 mm for go inspection applications
• Tool steel construction for wear resistance and dimensional stability
• 10 microfinish surface finish for consistent, repeatable contact
• Includes Certificate of Accuracy with NIST traceability
• Meets ASME B89.1 dimensional standards
• Compatible with set micrometers, verniers, and other measuring devices

Compatibility

Designed for use with standard plug gage handles; suitable for go inspection of 15 mm diameter features in production and quality-control environments. Compatible with set micrometers, verniers, and other precision measuring devices as stated by the manufacturer.

Installation Notes

Plug gages are installed and used by metrology technicians and quality inspectors familiar with ASME B89.1 gage application practices. Before use, clean the gage and the workpiece bore thoroughly to remove chips, oil, and debris that could cause false readings or surface damage. Never force a go gage through a bore; if resistance is felt, the workpiece may be out of tolerance or the bore may contain debris. Store the gage in its case when not in use to protect the finished surfaces and maintain traceability documentation.
