Vermont Gage 111346250 Class Zz Plus Plug Gage 0.4625 in

Product Description

The VERMONT GAGE 111346250 is a Class ZZ Plus plug gage used to inspect bore and hole diameters to a high degree of accuracy. Machined from tool steel and finished to a 10 microfinish surface, this gage measures a nominal diameter of 0.4625 inches with a tolerance of 0.0002 inches. It conforms to ASME B89.1 standards and ships with a Certificate of Accuracy with NIST traceability, making it suitable for documented quality-control workflows. Overall length is 2.0 inches. Metrology technicians, machinists, and quality inspectors rely on plug gages like this one for go-inspection of precision-machined components.

This plug gage is designed for go inspection applications where bore diameter verification is required. It is used alongside set micrometers, verniers, and other measuring devices to confirm dimensional conformance in production and inspection environments. The 0.4625-inch diameter makes it appropriate for precision bore work in both job-shop and manufacturing-floor quality control settings. Its compact 2.0-inch overall length allows use in standard gage blocks and fixtures without special accommodation.

Key Features

• Class ZZ Plus tolerance grade: 0.0002 inches for high-accuracy go inspection
• Tool steel construction for wear resistance and dimensional stability
• 10 microfinish surface finish reduces friction and protects bore surfaces during inspection
• Conforms to ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability for documented quality systems
• Compact 2.0-inch overall length fits standard plug gage handles and fixtures

Compatibility

Designed for use with standard plug gage handles and compatible with set micrometers, verniers, and other measuring devices for go inspection of 0.4625-inch nominal diameter bores per ASME B89.1.

Installation Notes

Plug gages are handled and deployed by metrology technicians and quality control inspectors; no power source or lockout procedure is required. Clean the gage and the bore being inspected before use to prevent debris from affecting the measurement or damaging the finished surface. Store the gage in its protective case when not in use to preserve the 10 microfinish and prevent corrosion. Do not force the gage into an undersized bore, as this will damage both the gage surface and the workpiece.
