Vermont Gage 111329650 Class Zz Plus Plug Gage 0.2965 in

Product Description

The VERMONT GAGE 111329650 is a Class ZZ Plus plug gage designed for precise bore and hole inspection in machine shops, toolrooms, and quality-control environments. Manufactured from tool steel, this plug gage measures a nominal diameter of 0.2965 inches with a tight tolerance of 0.0002 inches, making it suitable for verifying critical dimensional accuracy. The 10 microfinish surface treatment ensures consistent, low-friction contact with the workpiece. Machinists, tool-and-die makers, and quality technicians rely on this type of instrument for go-inspection applications where hole size conformance must be confirmed before parts advance in production.

This plug gage is intended for go inspection use and is compatible with standard gage block sets, set micrometers, verniers, and other precision measuring devices used for calibration and verification. It is well suited for light manufacturing, aerospace, and automotive toolroom environments where ASME B89.1 dimensional standards are required. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documented quality management systems and inspection audit requirements.

Compatibility

Designed for use with set micrometers, verniers, and other precision measuring devices in go inspection applications per ASME B89.1.

Installation Notes

Plug gages are handled and used by qualified machinists or quality technicians. Always clean the gage and the workpiece bore before use to prevent debris from affecting readings or damaging the gage surface. Store the gage in its protective case when not in use to preserve the microfinish and dimensional integrity. Do not force the gage into an undersized bore; excessive insertion force can damage both the gage and the part.
