Vermont Gage 112107320 Class Zz Plus Plug Gage 7.32mm

Product Description

The VERMONT GAGE 112107320 is a Class ZZ Plus plug gage machined from tool steel for use in precision dimensional inspection. The gage checks bore and hole diameters to verify conformance with tight manufacturing tolerances. With a nominal diameter of 7.32 mm and a tolerance of 0.005 mm (0.00508 mm actual), this gage delivers the accuracy required for Go inspection applications. The 10 microfinish surface coating minimizes wear during repeated use. Each unit ships with a Certificate of Accuracy traceable to NIST. Calibration professionals, machinists, and quality control technicians are the primary installers and users of this tool.

This plug gage is suited for Go inspection in production and metrology environments where hole diameter conformance must be verified against a defined tolerance. It is also used to set and verify micrometers, verniers, and other measuring devices. The overall length of 2.0 inches makes it compatible with standard gage handle assemblies used in bench and floor inspection setups. Applications span light manufacturing, aerospace component inspection, toolroom work, and any setting where ASME B89.1 dimensional standards are enforced.

Key Features

• Class ZZ Plus accuracy with 0.005 mm tolerance for precise Go inspection
• Tool steel construction for durability and dimensional stability under repeated use
• 10 microfinish surface coating reduces wear and maintains gage accuracy over time
• Includes Certificate of Accuracy with NIST traceability for documented calibration compliance
• Conforms to ASME B89.1 dimensional gage standards
• Overall length of 2.0 inches fits standard gage handle assemblies

Compatibility

Designed for use as a Go inspection gage for 7.32 mm nominal diameter bores and holes. Also used to set micrometers, verniers, and other measuring devices in toolroom and production inspection applications.

Installation Notes

Plug gages of this type are handled by calibration technicians, machinists, or quality control personnel — not field tradespeople. Store the gage in its protective case when not in use to prevent nicks or corrosion that would affect accuracy. Clean the gage and the bore being inspected before use to remove chips, coolant, or debris. Do not force the gage through an undersized hole, as this damages the gage surface and invalidates measurements.
