Vermont Gage 112309510 Class Zz Plus Plug Gage 9.51mm

Product Description

The VERMONT GAGE 112309510 is a Class ZZ Plus plug gage machined from tool steel for dimensional inspection of bored holes and machined features. It is used to verify that a hole meets minimum acceptable size requirements in a Go inspection application. The gage measures 9.51 mm in diameter with a tolerance of 0.00508 mm, and has an overall length of 2.0000 inches. A Certificate of Accuracy with NIST traceability is included, confirming conformance to ASME B89.1 standards. Machinists, quality technicians, and tool room personnel use this type of gage in production and incoming inspection environments.

This plug gage is suited for Go inspection use on holes nominally sized at 9.51 mm. It is also compatible with setting and verifying micrometers, verniers, and other precision measuring devices. Typical applications include CNC machined parts, precision assemblies, and any operation where hole diameter must be confirmed to close tolerance. The 10 microfinish surface coating supports consistent, repeatable contact with the workpiece during inspection.

Key Features

• Class ZZ Plus tolerance rating for high-accuracy Go inspection
• 9.51 mm nominal diameter with 0.00508 mm tolerance
• Tool steel construction for hardness and wear resistance
• 10 microfinish surface coating for consistent gage contact
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 dimensional gage standards

Compatibility

Designed for Go inspection of 9.51 mm diameter holes. Also suitable for setting 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 in inspection environments. Store the gage in its protective case when not in use to prevent damage to the precision ground surface. Clean the gage and the workpiece bore before use to ensure accurate readings and avoid premature wear. Never force the gage into an undersized hole, as this can damage the gage surface and compromise measurement accuracy.
