Vermont Gage 111329250 Class Zz Plus Plug Gage 0.2925 in

Product Description

The VERMONT GAGE 111329250 is a Class ZZ Plus plug gage used to verify bore and hole diameters to a tight dimensional tolerance. With a measurement diameter of 0.2925 inches and an overall length of 2 inches, this gage is designed for Go inspection applications where consistent, repeatable dimensional verification is required. Machined from tool steel and finished to a 10 microfinish surface, it holds a tolerance of 0.0002 inches. Each unit ships with a Certificate of Accuracy with NIST Traceability, making it suitable for calibrated inspection environments. Machinists, quality control technicians, and metrology professionals rely on this type of gage for production and incoming inspection work.

This plug gage is used in machine shops, manufacturing facilities, and inspection labs where bore diameters must be verified against a specified tolerance. It is appropriate for Go inspection checks and can also be used to set and verify micrometers, verniers, and other measuring devices. The compact 2-inch overall length makes it practical for bench use and easy storage in a gage kit or inspection station. It is suited for both light production inspection and calibration support tasks in general metalworking and precision machining environments.

Key Features

• Class ZZ Plus tolerance grade for Go inspection applications
• Measurement diameter of 0.2925 inches with a tolerance of 0.0002 inches
• Overall length of 2 inches for compact, bench-friendly use

• 10 microfinish surface for accurate, repeatable contact measurement
• Includes Certificate of Accuracy with NIST Traceability; conforms to ASME B89.1

Compatibility

Designed for use as a Go plug gage in bore inspection and as a reference standard for setting micrometers, verniers, and other measuring devices in accordance with ASME B89.1.

Installation Notes

Plug gages should be handled by metrology or quality control personnel familiar with gage care and proper Go inspection technique. Store the gage in a clean, dry environment and avoid contact with abrasive surfaces that could alter the finish or affect dimensional accuracy. Do not force the gage into a bore; controlled, light hand pressure is standard practice. Reference the included NIST-traceable Certificate of Accuracy when incorporating this gage into a calibration program.
