Vermont Gage 111324850 Class Zz Plus Plug Gage 0.2485 in

Product Description

The VERMONT GAGE 111324850 is a Class ZZ Plus plug gage used to verify bore and hole diameters in precision inspection work. Measuring 0.2485 inches in diameter with a tolerance of 0.0002 inches, this gage delivers the accuracy required for go inspection tasks. Manufactured from tool steel with a 10 microfinish surface, it provides consistent and repeatable results across high-volume inspection applications. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting quality management and documentation requirements. Machinists, quality control technicians, and calibration specialists are the primary users of this tool.

This plug gage is suited for use in production and inspection environments where precise bore verification is required. Common applications include go inspection of drilled, reamed, or bored holes, as well as setting and verifying micrometers, verniers, and other dimensional measuring devices. It is built to ASME B89.1 standards, making it appropriate for both shop-floor and laboratory metrology settings where documented traceability is required by quality systems or customer specifications.

Key Features

• 0.2485 inches measurement diameter with 0.0002 inches tolerance for high-precision bore inspection
• 10 microfinish surface for consistent, low-wear gage contact
• Tool steel construction for durability in production inspection environments
• Includes Certificate of Accuracy with NIST traceability for quality system compliance
• Built to ASME B89.1 dimensional standards
• Overall length of 2.0 inches for easy single-hand handling and storage

Compatibility

Designed for use as a go inspection gage and as a reference standard for setting micrometers, verniers, and other dimensional measuring instruments in precision metrology and manufacturing inspection applications.

Installation Notes

Plug gages should be handled by qualified metrology or quality control personnel. Clean gage and workpiece surfaces before use to prevent contamination from affecting measurement results. Store the gage in its protective case away from temperature extremes to maintain dimensional stability. Do not force the gage into an undersized bore, as this can damage the gage surface and compromise accuracy.
