Vermont Gage 111323950 Class Zz Plus Plug Gage 0.2395 in

Product Description

The VERMONT GAGE 111323950 is a Class ZZ Plus plug gage designed for precision dimensional inspection of 0.2395-inch diameter holes and bores. Manufactured from tool steel with a 10 microfinish surface, this gage delivers reliable Go inspection performance in production and quality control environments. Each unit ships with a Certificate of Accuracy that includes NIST traceability, confirming conformance to ASME B89.1 standards. With a tolerance of 0.0002 inches, this gage is suited for applications that demand tight measurement verification. Machinists, quality technicians, and calibration professionals are the primary users of this type of precision tooling.

This plug gage is used in Go inspection routines to verify that a bored, drilled, or reamed hole falls within the specified dimensional tolerance. At 2.0 inches overall length, it handles comfortably in bench or floor-level inspection stations. Typical applications include setting and verifying micrometers, verniers, and other measuring devices, as well as direct hole inspection on machined components. It is well suited for both job shop and high-volume production quality control workflows where ASME B89.1 compliance is required.

Key Features

• Measures 0.2395-inch diameter with a tolerance of 0.0002 inches for tight Go inspection work
• Tool steel construction for durability and dimensional stability under repeated use
• 10 microfinish surface reduces wear and ensures consistent gage-to-part contact
• Conforms to ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability for calibration documentation
• 2.0-inch overall length for practical hand-held use at the inspection station

Compatibility

Designed for Go inspection of 0.2395-inch diameter holes and for use as a setting reference with micrometers, verniers, and other precision measuring devices conforming to ASME B89.1 requirements.

Installation Notes

Plug gages are handled and applied by quality technicians and machinists during inspection routines. Clean the gage and the workpiece bore thoroughly before use to prevent contamination that can affect measurement accuracy. Do not force the gage into an undersized hole, as this can damage both the gage and the workpiece. Store in a protective case away from temperature extremes to maintain dimensional stability and protect the calibrated surface finish.
