Vermont Gage 112100300 Class Zz Plus Plug Gage 0.3 Mm

Product Description

The VERMONT GAGE 112100300 is a Class ZZ Plus plug gage designed for precision dimensional inspection of small-diameter bores and holes. Built from tool steel with a 10 microfinish surface coating, this gage measures 0.30 mm in diameter and carries a tolerance of 0.005 mm. At an overall length of 2.0000 inches, it is suited for hand-held use in inspection environments. Each unit ships with a Certificate of Accuracy backed by NIST traceability, meeting ASME B89.1 standards. Metrology technicians, tool-and-die shops, and quality control departments use this type of gage for Go inspection checks on precision-machined components.

This plug gage is used in Go inspection applications where small-bore dimensional verification is required. It is compatible with standard gage handle holders and works alongside set micrometers, verniers, and other precision measuring devices. Typical use environments include machine shops, production floors, and metrology labs where tight tolerances on small bores must be verified consistently. The 0.30 mm diameter makes it appropriate for applications involving micro-machined parts, small-diameter drilled holes, and similar precision features.

Key Features

• Class ZZ Plus tolerance grade with 0.005 mm tolerance for high-precision inspection
• Tool steel construction for durability and wear resistance in repeated use
• 10 microfinish surface coating for accurate, consistent contact with bore surfaces
• NIST-traceable Certificate of Accuracy included with each unit
• Meets ASME B89.1 dimensional gage standards
• Compact 2.0000-inch overall length for easy hand manipulation

Compatibility

Designed for use with standard gage handle holders and compatible with set micrometers, verniers, and other precision measuring devices per the manufacturer application designation for Go inspection tasks.

Installation Notes

Plug gages of this type are handled and used by metrology technicians and quality control personnel rather than installed in a system. Keep the gage clean and lightly oiled when stored to prevent corrosion on the tool steel body. Avoid dropping or contacting the gage face against hard surfaces, as any nick or burr on the 0.30 mm diameter will compromise measurement accuracy. Follow your facility calibration schedule and refer to ASME B89.1 for gage handling and storage guidelines.
