Vermont Gage 112309450 Class Zz Plus Plug Gage 9.45 Mm

Product Description

The VERMONT GAGE 112309450 is a Class ZZ Plus plug gage machined from tool steel for dimensional go inspection of bored, drilled, and reamed holes. It measures 9.45 mm in diameter with a tolerance of 0.005 mm, making it suitable for precision verification work where close-tolerance hole acceptance is required. The gage features a 10 microfinish surface coating that reduces wear on the gage and the workpiece during repeated use. At 2.0 inches overall length and approximately 0.07 pounds, it is a compact, hand-held inspection tool used in production and quality-control environments by machinists, tool-and-die makers, and metrology technicians.

This plug gage is used in go inspection applications to verify that a hole has been machined to the minimum acceptable size before the part advances through production. It is compatible with standard gage handle systems and is commonly used alongside set micrometers, vernier calipers, and other dimensional measuring devices for in-process and final inspection. The 9.45 mm diameter fits applications in light manufacturing, precision machining, and quality assurance where ASME B89.1 conformance is required. Each unit ships with a Certificate of Accuracy with NIST traceability, supporting documented inspection programs and calibration records.

Key Features

• Class ZZ Plus tolerance rating: 0.005 mm tolerance for precise go inspection
• 10 microfinish surface finish reduces gage wear and protects hole finish during use
• Tool steel construction provides durability under repeated inspection cycles
• Includes Certificate of Accuracy with NIST traceability for calibration documentation
• Conforms to ASME B89.1 standards for plain plug gages
• Compact 2.0-inch overall length fits standard gage handles

Compatibility

Designed for use with standard plug gage handle systems in go inspection setups. Compatible with set micrometers, verniers, and other dimensional measuring devices as stated by the manufacturer. Intended for applications requiring ASME B89.1 conformance.

Installation Notes

Plug gages are used by qualified metrology technicians and machinists in inspection environments. Always ensure the workpiece and gage are clean and free of chips, coolant, or debris before use, as contamination will produce inaccurate readings and accelerate gage wear. Do not force the gage through an undersize hole; apply light, consistent hand pressure only. Store the gage in its protective case when not in use to preserve the surface finish and dimensional integrity.
