Vermont Gage 112306110 Class Zz Plus Plug Gage 6.11mm

Product Description

The VERMONT GAGE 112306110 is a Class ZZ Plus plug gage designed for precise dimensional inspection of bored, drilled, and reamed holes. It checks a nominal hole diameter of 6.11 mm with a tolerance of 0.00508 mm, providing the tight accuracy required for go-inspection work. The gage is manufactured from tool steel and features a 10 microfinish surface coating that supports repeatable, low-wear contact with the workpiece. A Certificate of Accuracy with NIST Traceability is included, making it suitable for use in calibrated inspection environments. Machinists, quality technicians, and tool room personnel use this gage as a direct check or as a reference standard for setting micrometers, verniers, and other measuring devices.

This plug gage is suited for production floor and inspection room use wherever go-inspection of 6.11 mm diameter features is required. It is also used to set and verify the calibration of micrometers, vernier calipers, and similar hand measuring instruments. The overall length of 2.0000 inches makes it compatible with standard gage handle systems. Applications span general metalworking, precision machining, and quality assurance operations in both job shop and production environments.

Key Features

• 6.11 mm nominal diameter with 0.00508 mm Class ZZ Plus tolerance for tight go-inspection work
• Tool steel construction for durability and resistance to wear during repeated use
• 10 microfinish surface coating supports accurate, consistent contact measurement
• Includes Certificate of Accuracy with NIST Traceability for use in calibrated inspection programs
• Meets ASME B89.1 standards for plain plug gages
• 2.0000 inch overall length compatible with standard gage handle systems

Compatibility

Designed for go-inspection of 6.11 mm diameter bored, drilled, or reamed holes and for setting micrometers, verniers, and other hand measuring devices per ASME B89.1 requirements.

Installation Notes

Plug gages are handled and used by quality technicians and machinists - no permanent installation is required. Clean and lightly oil the gage before and after each use to prevent corrosion and maintain surface finish. Never force the gage into a hole; if resistance is encountered during go-inspection, the feature is undersized and the gage should be withdrawn without applying lateral pressure. Store in the provided case or a padded gage tray away from other metal tooling to protect the lapped surface.
