Vermont Gage 112107300 Class Zz Plus Plug Gage 7.3 Mm

Product Description

The VERMONT GAGE 112107300 is a Class ZZ Plus plug gage machined from tool steel for precise internal diameter inspection. It measures 7.3 mm in diameter with a tolerance of 0.005 mm, making it suitable for tight-tolerance go/no-go inspection workflows. The 10 microfinish surface provides consistent contact and minimizes wear during repeated use. Each unit ships with a Certificate of Accuracy traceable to NIST, satisfying documentation requirements for ISO and quality-system audits. The overall length is 2.0 inches. Machinists, quality technicians, and toolroom professionals use this gage to verify bore sizes on machined components, fixtures, and assemblies.

This plug gage is designed for go inspection applications and is compatible with use alongside set micrometers, verniers, and other precision measuring devices. It is well suited for production floor inspection, toolroom verification, and incoming quality control in both job-shop and high-volume manufacturing environments. The ASME B89.1 standard governs its dimensional accuracy, making it appropriate wherever that specification is called out in inspection plans or customer quality requirements.

Compatibility

Designed for use in go inspection applications alongside set micrometers, verniers, and other precision measuring devices. Conforms to ASME B89.1 dimensional standards.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no power source or utility shutoff is required. Clean the gage and the bore being checked before use to prevent debris from affecting the reading or damaging the gage surface. Store the gage in its protective case when not in use to preserve the microfinish and prevent corrosion. Handle with clean, dry hands or lint-free gloves to avoid introducing oils that can affect measurement accuracy.
