Vermont Gage 112306650 Class Zz Plus Plug Gage 6.65 Mm

Product Description

The VERMONT GAGE 112306650 is a Class ZZ Plus plug gage machined from tool steel and used to verify bore diameters to tight dimensional tolerances. With a nominal diameter of 6.65 mm and a tolerance of 0.00508 mm, this gage delivers the precision required for Go inspection tasks in production and quality-control environments. The 10 microfinish surface treatment reduces wear and maintains dimensional integrity over repeated use cycles. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for use in documented inspection programs. Machinists, toolroom technicians, and quality engineers are the primary users.

This plug gage is intended for Go inspection of machined bores, drilled holes, and other internal features where a 6.65 mm nominal diameter must be confirmed. It is also appropriate for setting and verifying micrometers, verniers, and other comparative measuring devices. Typical environments include production floor inspection stations, toolrooms, and metrology labs in both job-shop and high-volume manufacturing settings. The 2.0-inch overall length fits standard gage-handle holders used throughout the industry.

Key Features

• Class ZZ Plus tolerance class for Go inspection with 0.00508 mm tolerance
• Tool steel construction for durability and dimensional stability
• 10 microfinish surface for reduced wear and consistent gaging contact
• NIST-traceable Certificate of Accuracy included with each unit
• Conforms to ASME B89.1 standards
• 2.0-inch overall length compatible with standard gage-handle holders

Compatibility

Suitable for use with standard plug gage handles and compatible with Go inspection applications for 6.65 mm nominal bore diameters. Also used to set micrometers, verniers, and other measuring devices requiring a calibrated reference.

Installation Notes

Plug gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion and measurement error from skin oils. Store in the provided case or protective sleeve when not in use to protect the gaging surface. Do not force the gage into a bore; excessive insertion force can damage both the gage and the workpiece. Periodic cleaning and inspection for wear are recommended to maintain accuracy within the stated tolerance.
