Vermont Gage 111149300 Class Zz Plus Plug Gage 0.493 in

Product Description

The VERMONT GAGE 111149300 is a Class ZZ Plus plug gage designed for go inspection of bored, drilled, and reamed holes at a nominal diameter of 0.493 inches. Manufactured from tool steel with a 10 microfinish surface, this gage provides a tolerance of 0.0002 inches, meeting the requirements of ASME B89.1. Each unit ships with a Certificate of Accuracy that carries NIST traceability, making it suitable for use in quality-control and incoming-inspection environments. Machinists, toolroom technicians, and metrology personnel use Class ZZ Plus gages for verifying hole diameter conformance in production and inspection workflows.

This plug gage is intended for go inspection applications in manufacturing and dimensional inspection settings. It is compatible with use alongside set micrometers, verniers, and other precision measuring devices where hole diameter verification is required. The 2.0-inch overall length provides a practical working reach for standard bore-inspection tasks. Typical users include quality technicians and machining professionals working to dimensional tolerances in precision fabrication environments.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for precise go inspection
• Tool steel construction for durability and wear resistance in production environments
• 10 microfinish surface for consistent, repeatable gage contact
• Meets ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability
• 2.0-inch overall length suited to standard bench and floor inspection use

Compatibility

Designed for use in go inspection of holes nominally sized at 0.493 inches, and compatible with set micrometers, verniers, and other precision measuring devices as stated by the manufacturer.

Installation Notes

Plug gages are handled and used by qualified metrology or quality-control personnel following established inspection procedures. Store the gage in its protective case when not in use to prevent surface damage or corrosion. Clean the gage and the workpiece bore before use to ensure accurate readings. Do not force the gage into an undersized bore, as this will damage the gage surface and compromise measurement accuracy.
