Vermont Gage 111303450 Class Zz Plus Plug Gage 0.0345 in

Product Description

The VERMONT GAGE 111303450 is a Class ZZ Plus plug gage designed for precision dimensional inspection of small-diameter bores and holes. Measuring 0.0345 inches in diameter with a tolerance of 0.0002 inches, this gage delivers the accuracy required for go-inspection workflows in quality control and metrology environments. Manufactured from tool steel and finished to a 10 microfinish surface, it maintains dimensional stability under repeated use. Each unit ships with a Certificate of Accuracy traceable to NIST, satisfying documentation requirements for calibrated inspection tooling in production and lab settings. Licensed metrologists, QC technicians, and precision machinists are the primary users.

This plug gage is suited for go inspection of tight-tolerance bores in precision machined components. It also serves as a reference standard for setting micrometers, verniers, and other dimensional measuring devices where a known, certified diameter is required. Typical applications include incoming inspection, in-process quality checks, and calibration support in manufacturing facilities working to close tolerances. The 2.0-inch overall length provides adequate grip and handling during single-handed inspection passes.

Key Features

• Class ZZ Plus tolerance class: 0.0002 inches, suitable for go-inspection of precision bores
• 10 microfinish surface for consistent, low-friction gage contact
• Tool steel construction for hardness and dimensional stability
• Conforms to ASME B89.1 dimensional standards
• Includes Certificate of Accuracy with NIST traceability for calibration documentation
• 2.0-inch overall length for controlled single-handed use

Compatibility

Designed as an OEM-style precision reference for go inspection of bores at 0.0345 inches nominal diameter and for setting micrometers, verniers, and other calibrated measuring devices requiring a certified plug reference.

Installation Notes

Plug gages are handled and stored by metrology or quality control personnel, not field-installed trades. Keep the gage clean and lightly oiled when stored to prevent corrosion of the tool steel. Never force the gage into a bore; apply only light, axial hand pressure during inspection passes. Store in the provided case away from heat sources and abrasive materials to preserve the 10 microfinish surface and dimensional accuracy.
