Vermont Gage 111154300 Class Zz Plus Plug Gage 0.543 in

Product Description

The VERMONT GAGE 111154300 is a Class ZZ Plus plug gage designed for precision dimensional inspection of bores, holes, and internal features. Machined from tool steel, this plug gage measures a nominal diameter of 0.543 inches with a tolerance of 0.0002 inches, making it suitable for go inspection applications where tight dimensional control is required. The working surface carries a 10 microinch finish. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting quality documentation requirements in calibration and inspection environments. Metrology technicians, tool room machinists, and quality control professionals are the primary users.

This plug gage is used in go inspection routines to verify that bored, drilled, or reamed features fall within the minimum acceptable size limit. It is also appropriate for setting and verifying micrometers, verniers, and other measuring devices requiring a traceable reference standard. Typical applications include precision machining shops, gauge calibration labs, and manufacturing quality control departments where ASME B89.1 compliance is required. The 2.0-inch overall length provides adequate handle clearance for standard hand-held inspection use.

Key Features

• Tool steel construction for wear resistance and dimensional stability
• 10 microinch surface finish on the gauging element
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 standard
• 2.0-inch overall length for comfortable hand-held use

Compatibility

Designed for go inspection of 0.543-inch nominal diameter features and for use as a reference standard when setting micrometers, verniers, and other precision measuring devices.

Installation Notes

Plug gages are handled and applied by metrology technicians or trained quality control personnel. Keep the gauging surface clean and lightly oiled when not in use to prevent corrosion and wear. Never force a plug gage into an undersized feature, as this can damage the gauge surface and invalidate calibration. Store in the provided case or a padded gauge block tray away from heat sources and contaminants to maintain accuracy.
