Vermont Gage 112106600 Class Zz Plus Plug Gage 6.6mm

Product Description

The VERMONT GAGE 112106600 is a Class ZZ Plus plug gage designed for dimensional inspection of bored holes and machined features. It measures 6.6 mm in diameter with a tolerance of 0.005 mm, making it suitable for high-precision go inspection work. Manufactured from tool steel and finished to a 10 microfinish surface quality, this gage delivers consistent, repeatable results. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documentation requirements for quality management systems. Machinists, toolroom technicians, and quality control inspectors use this type of gage as part of standard incoming and in-process measurement routines.

This plug gage is used in toolroom, production floor, and quality lab environments where hole diameter verification is required. It is suited for go inspection of 6.6 mm bored, reamed, or drilled features in both ferrous and non-ferrous workpieces. It is also compatible with set micrometer calibration and verification routines, as well as use alongside verniers and other precision measuring devices. The overall length of 2.0 inches fits standard handle configurations used across general metalworking and precision machining applications.

Key Features

• 6.6 mm diameter with 0.005 mm tolerance for tight go inspection requirements
• Tool steel construction for wear resistance and dimensional stability
• 10 microfinish surface for accurate seating and consistent gage contact
• Includes Certificate of Accuracy with NIST traceability for QMS compliance
• Conforms to ASME B89.1 standards for plain plug gages
• 2.0 inch overall length fits standard plug gage handles

Compatibility

Designed for use in go inspection applications and for setting micrometers, verniers, and other precision measuring devices requiring a 6.6 mm reference diameter.

Installation Notes

Plug gages are installed by hand and require no tools for use. Before use, clean both the gage and the workpiece feature with a lint-free cloth to remove debris, oils, or chips that could affect readings. Store the gage in its case when not in use and avoid dropping or stacking with other metal tooling to prevent surface damage. Periodic recalibration against a traceable standard is recommended per your facility quality schedule.
