Vermont Gage 112109260 Class Zz Plus Plug Gage 9.26 Mm

Product Description

The VERMONT GAGE 112109260 is a Class ZZ Plus cylindrical plug gage manufactured from tool steel for dimensional go inspection work. It checks a 9.26 mm bore or hole diameter against a defined tolerance of 0.00508 mm, confirming that a workpiece opening meets its minimum acceptable size. The gage features a 10 microfinish surface coating that minimizes wear and maintains measurement integrity over repeated use. Overall length is 2.0 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Machinists, quality technicians, and tool room personnel use this gage in production and inspection environments.

This plug gage is suited for go inspection of precision bored holes, drilled passages, and machined features measuring 9.26 mm in diameter. It is compatible with standard gage handle systems and is commonly used alongside micrometers, verniers, and other dimensional measuring devices for process control and first-article inspection. The Class ZZ Plus tolerance class is appropriate for general-purpose inspection where tighter gage tolerances are required beyond standard Class ZZ. Applicable in both job shop and production floor settings where bore size conformance must be verified before assembly.

Key Features

• Go inspection plug gage for 9.26 mm diameter bores
• Class ZZ Plus tolerance: 0.00508 mm for precise dimensional verification
• Tool steel construction for durability and wear resistance
• 10 microfinish surface coating for accurate, repeatable contact
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 dimensional gage standards

Compatibility

Designed for use with standard cylindrical plug gage handles and compatible with micrometers, verniers, and other dimensional measuring devices used in go inspection applications per ASME B89.1.

Installation Notes

Plug gages should be handled by qualified inspection or toolroom personnel. Clean the gage and the bore being inspected before use to remove chips, oils, or debris that could affect measurement accuracy. Do not force the gage through a hole; apply light, consistent hand pressure only. Store the gage in its protective case when not in use to prevent surface damage and corrosion.
