Vermont Gage 111124300 Class Zz Plus Plug Gage 0.243 in

Product Description

The VERMONT GAGE 111124300 is a Class ZZ Plus plug gage designed for precise hole diameter inspection in machining and metrology applications. With a 0.243 inch nominal diameter and a tight tolerance of 0.0002 inches, this plug gage delivers reliable go-inspection performance for verifying bore dimensions on the shop floor or in the inspection lab. The gage is machined from tool steel and features a 10 microfinish surface, reducing gauge-to-part contact wear and supporting repeatable readings. It ships with a Certificate of Accuracy with NIST traceability, making it suitable for documented quality control processes. Licensed metrology technicians and quality inspection professionals are the primary users.

This plug gage is well suited for dimensional verification in precision manufacturing environments, including machining shops, tool rooms, and inspection departments. It is used to confirm hole diameters during production runs and final inspection. The 0.243 inch diameter makes it applicable to close-tolerance drilled or reamed holes in metal components. It is also compatible with the calibration and setting of micrometers, verniers, and other measuring devices requiring a certified reference standard. The compact 2.0 inch overall length fits standard gage handles for bench or in-process use.

Key Features

• Class ZZ Plus tolerance grade: 0.0002 inches for high-accuracy go inspection
• Tool steel construction for durability and wear resistance in production environments
• 10 microfinish surface finish minimizes wear and supports consistent contact
• Certificate of Accuracy with NIST traceability included for documented QC compliance
• Meets ASME B89.1 standards for plug gage dimensional accuracy
• 2.0 inch overall length compatible with standard gage handle holders

Compatibility

Designed for go inspection of 0.243 inch diameter holes. Also suitable for setting micrometers, verniers, and other measuring devices requiring a certified reference standard, per the application data provided by the manufacturer.

Installation Notes

Plug gages should be handled by qualified inspection or metrology personnel following shop quality procedures. Clean and deburr the workpiece bore before use to avoid false readings and premature gage wear. Store the gage in its protective case when not in use to preserve the surface finish and dimensional integrity. Periodic re-certification against NIST-traceable standards is recommended as part of a formal calibration program.
