Vermont Gage 111148000 Class Zz Plus Plug Gage 0.48 in

Product Description

The VERMONT GAGE 111148000 is a Class ZZ Plus plug gage used to perform go inspection checks on machined bores, holes, and cylindrical features. Manufactured from tool steel, this plug gage measures a nominal diameter of 0.48 inches with a tolerance of 0.0002 inches and a surface finish of 10 microinch Ra. It is used by machinists, quality control technicians, and tool-room professionals to verify that a workpiece opening meets minimum size requirements. Each unit ships with a Certificate of Accuracy backed by NIST traceability, confirming conformance to ASME B89.1 standards.

This plug gage is suited for go inspection applications in production and tool-room environments. It is commonly used alongside set micrometers, verniers, and other precision measuring devices to establish or verify dimensional reference points. The 0.48-inch diameter and 2.0-inch overall length make it practical for benchtop and inline inspection of close-tolerance bores in both light manufacturing and precision machining settings.

Key Features

• Class ZZ Plus tolerance rating with 0.0002-inch tolerance for precise go inspection
• Tool steel construction for wear resistance and dimensional stability
• 10 microinch Ra surface finish for consistent, repeatable gaging contact
• Conforms to ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability
• 2.0-inch overall length suits standard bench and inline inspection setups

Compatibility

Designed for use in go inspection of cylindrical bores and holes; also suitable for setting and verifying micrometers, verniers, and other precision measuring devices requiring a 0.48-inch reference diameter.

Installation Notes

Plug gages are handled and used by quality control technicians and machinists trained in precision measurement. 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 each use to ensure accurate results. Do not force the gage into an undersized opening, as this can damage the gage surface and affect calibration.
