Vermont Gage 112104080 Class Zz Plus Plug Gage 4.08 Mm

Product Description

The VERMONT GAGE 112104080 is a Class ZZ Plus plug gage designed for dimensional inspection in precision measurement environments. It checks bore diameters to confirm Go acceptance criteria, making it a standard tool for quality control technicians and metrologists working to tight tolerances. The gage features a 4.08 mm diameter, a tolerance of 0.005 mm, and a 10 microfinish surface coating on the gaging member. Constructed from tool steel, the 112104080 is built to withstand repeated use in production and inspection settings. An overall length of 2.0000 inches supports handling in standard gage handle assemblies.

This plug gage is suited for Go inspection applications in manufacturing and metrology labs where bore acceptance must be verified against ASME B89.1 standards. It is commonly used alongside set micrometers, verniers, and other precision measuring devices to calibrate or verify dimensional conformance. Every unit ships with a Certificate of Accuracy traceable to NIST, supporting quality management system documentation requirements in ISO and AS9100 registered facilities.

Key Features

• Class ZZ Plus tolerance class: 0.005 mm tolerance for high-precision Go inspection
• 4.08 mm gaging diameter machined from tool steel for durability and wear resistance
• 10 microfinish surface on the gaging member reduces friction and wear during use
• Meets ASME B89.1 standards for plain limit gages
• Includes Certificate of Accuracy with NIST traceability for compliance documentation
• 2.0000-inch overall length compatible with standard plug gage handles

Compatibility

Designed for use with standard plug gage handle assemblies and suitable for Go inspection of 4.08 mm bores. Compatible with set micrometers, verniers, and other precision measuring devices as noted in the product application data.

Installation Notes

Plug gages should be handled and stored per ASME B89.1 guidelines to preserve accuracy and surface finish. Clean the gaging member and the bore with a lint-free cloth before each inspection to prevent debris from affecting readings or causing wear. Do not force the gage member into a bore; apply light, consistent pressure only. Calibration verification should be performed at regular intervals using NIST-traceable reference standards.
