Vermont Gage 111313850 Class Zz Plus Plug Gage 0.1385 in

Product Description

The VERMONT GAGE 111313850 is a Class ZZ Plus plug gage designed to verify bore and hole diameters to a nominal size of 0.1385 inches. Built from tool steel with a 10 microfinish surface, it holds a tolerance of 0.0002 inches, making it suitable for precision go inspection work. The gage ships with a Certificate of Accuracy that carries NIST traceability, confirming it meets ASME B89.1 dimensional standards. Machinists, quality technicians, and tool-room professionals use this type of gage in production and inspection environments where tight dimensional control is required.

This plug gage is intended for go inspection applications where a controlled hole or bore must be verified against a minimum acceptable diameter. It is also appropriate for setting and verifying the calibration of micrometers, verniers, and other precision measuring devices. At 2.0 inches overall length, it fits comfortably in a hand-held inspection workflow on the shop floor or in a calibration lab. It is well suited to light manufacturing, precision machining, and quality-assurance departments working to ASME dimensional tolerances.

Key Features

• Nominal diameter of 0.1385 inches with a 0.0002-inch tolerance for precise go/no-go inspection
• Tool steel construction provides hardness and wear resistance in production environments
• 10 microfinish surface finish reduces measurement variation caused by surface irregularities
• Includes Certificate of Accuracy with NIST traceability, supporting ISO and quality-system documentation requirements
• Meets ASME B89.1 standards for dimensional gaging
• Suitable for setting micrometers, verniers, and other calibrated measuring instruments

Compatibility

Designed for go inspection of holes and bores at 0.1385 inches nominal diameter, and for use as a setting standard with micrometers, verniers, and other precision measuring devices per the manufacturer application data.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no permanent installation is required. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel body. Do not force the gage into an undersized hole, as this can damage the gage surface and invalidate calibration. Store in a protective case away from temperature extremes to maintain dimensional stability.
