Vermont Gage 112115200 Class Zz Plus Plug Gage 15.2 Mm

Product Description

The VERMONT GAGE 112115200 is a Class ZZ Plus cylindrical plug gage machined to a 15.20 mm diameter with a tolerance of 0.00508 mm. It is used to verify bore and hole dimensions in manufactured parts and assemblies. Made from tool steel with a 10 microfinish surface coating, this gage delivers the dimensional stability and surface quality required for reliable go-inspection work. At 2.0000 inches overall length, it fits standard gage handles used in production and quality-control environments. Installation and use is performed by metrology technicians, machinists, and quality inspectors.

This plug gage is suited for go inspection applications where a bore must be confirmed to accept a minimum allowable diameter. It is also used to set micrometers, verniers, and other measuring devices requiring a traceable reference standard. Typical environments include machine shops, manufacturing floors, and inspection labs working to ASME B89.1 dimensional standards. Each unit ships with a Certificate of Accuracy with NIST traceability, supporting documentation requirements in calibrated inspection programs. It is appropriate for both production-line checking and precision metrology setups in light manufacturing and tool-and-die operations.

Key Features

• Class ZZ Plus tolerance rating with 0.00508 mm tolerance for high-accuracy go inspection
• Tool steel construction provides hardness and dimensional stability under repeated use
• 10 microfinish surface coating minimizes wear and ensures consistent contact during gauging
• Meets ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability for calibration documentation
• 2.0000 inch overall length fits standard commercial gage handles

Compatibility

Designed for use with standard plug gage handles and suitable for go inspection of 15.20 mm diameter bores. Also compatible with setup and calibration of micrometers, verniers, and other measuring devices requiring a traceable cylindrical reference.

Installation Notes

Plug gages are handled and used by machinists, quality technicians, and calibration specialists. Before use, clean the gage and the bore being inspected to remove chips, oil, and debris that could affect the reading. Apply light, consistent insertion force only — forcing a go gage into an undersize bore can damage the gage surface and yield false acceptance. Store the gage in its protective case when not in use to preserve the 10 microfinish surface and prevent corrosion.
