Vermont Gage 112309370 Class Zz Plus Plug Gage 9.37 Mm

Product Description

The VERMONT GAGE 112309370 is a Class ZZ Plus plug gage manufactured from tool steel for use in dimensional inspection and measurement verification applications. Sized at 9.37 mm in diameter with a tolerance of 0.005 mm, this gage delivers the precision required for go-inspection workflows on the shop floor or in a quality control environment. The 10 microfinish surface coating reduces wear and ensures consistent, repeatable contact with the bore being measured. Overall length is 2.0 inches. Each unit ships with a Certificate of Accuracy with NIST traceability, making it suitable for documented inspection programs.

This plug gage is designed for go inspection use with bore gauging setups and for setting and verifying micrometers, verniers, and other precision measuring devices. It is well suited for machinists, quality technicians, and metrology professionals working in production or inspection environments where tight bore tolerances must be confirmed. The Class ZZ Plus designation meets ASME B89.1 standards, making it appropriate for both in-process inspection and final acceptance gauging in manufacturing settings.

Key Features

• 9.37 mm diameter with 0.005 mm tolerance for tight bore inspection
• Class ZZ Plus classification per ASME B89.1
• 10 microfinish surface coating for reduced wear and consistent contact
• Tool steel construction for durability in production environments
• Includes Certificate of Accuracy with NIST traceability
• 2.0 inch overall length for standard plug gage handle compatibility

Compatibility

Designed as an OEM-style Class ZZ Plus plug gage for go inspection use with standard plug gage handles, and for setting micrometers, verniers, and other precision measuring devices per ASME B89.1.

Installation Notes

Plug gages should be handled and stored carefully to prevent damage to the gauging surface. Inspect the gage and bore for burrs or debris before use. Do not force the gage into an undersized bore, as this can damage both the gage and the workpiece. When used for setting measuring instruments, follow the instrument manufacturer's calibration procedure and document traceability to maintain inspection record integrity.
