Vermont Gage 111314550 Class Zz Plus Plug Gage 0.1455 in

Product Description

The VERMONT GAGE 111314550 is a Class ZZ Plus plug gage designed for precision dimensional inspection of bored holes, drilled passages, and machined features at a nominal diameter of 0.1455 inches. Built from tool steel, it holds a tolerance of 0.0002 inches and carries a surface finish of 10 microinch Ra, meeting the dimensional verification requirements of ASME B89.1. Each unit ships with a Certificate of Accuracy backed by NIST traceability, making it suitable for calibration-conscious shop environments. Machinists, quality technicians, and metrologists use this gage as a go-inspection reference standard.

This plug gage is appropriate for use in precision machining shops, tool rooms, and quality control labs where tight hole tolerances must be verified. It also serves as a calibration reference for setting micrometers, verniers, and other measuring devices to a known diameter standard. At 2.0 inches overall length and 0.1455 inches diameter, it fits standard gage handle systems used in both production inspection and bench-top metrology workflows.

Key Features

• Class ZZ Plus tolerance class at 0.0002 inches for high-accuracy go inspection
• 10 microinch Ra surface finish for consistent, repeatable contact measurement
• Tool steel construction for wear resistance and dimensional stability
• Complies with ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability
• Compatible with standard plug gage handles for efficient in-process inspection

Compatibility

Designed as an OEM-style precision reference for go inspection of features at 0.1455 inches diameter, and for setting micrometers, verniers, and other measuring devices requiring a certified diameter standard.

Installation Notes

Plug gages should be handled and stored by qualified quality technicians or machinists following shop metrology protocols. Clean the gage and the feature under inspection before use to prevent debris from affecting the measurement. Do not force the gage into an undersized hole, as this can damage both the gage and the workpiece. Store in a protective case away from temperature extremes to maintain dimensional integrity over time.
