Vermont Gage 111120200 Class Zz Plus Plug Gage 0.202 in

Product Description

The VERMONT GAGE 111120200 is a Class ZZ Plus plug gage designed for precision dimensional inspection of 0.202-inch diameter bores and holes. Built from tool steel with a 10 microfinish surface, this gage delivers a tolerance of 0.0002 inches, meeting ASME B89.1 standards for gage accuracy. It ships with a Certificate of Accuracy with NIST Traceability, making it suitable for quality control environments where documented calibration is required. Machinists, toolroom technicians, and quality inspection personnel use this gage for go-type inspection checks on drilled, reamed, or bored features.

This plug gage is suited for go inspection applications including checking hole diameter acceptance on production parts. It is also used as a reference standard for setting micrometers, verniers, and other measuring devices. The overall length of 2.0 inches provides adequate handling clearance for bench and floor inspection use. It is appropriate for both job shop and production floor environments where consistent, repeatable hole verification is required.

• Tool steel construction for durability in production and toolroom use
• Meets ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST Traceability for documented quality systems
• 2.0-inch overall length suits standard bench inspection use

Compatibility

Designed as a go-type inspection gage for 0.202-inch diameter bores; also compatible for use as a setting reference with micrometers, verniers, and other precision measuring devices.

Installation Notes

Plug gages are handled and applied by machinists and quality inspection technicians, not installed in the traditional sense. Before use, clean both the gage and the workpiece bore to remove chips, oil, and debris that could affect the reading. Apply light, controlled hand pressure when inserting the gage — never force it. Store the gage in its protective case and handle with clean gloves or lint-free cloth to prevent corrosion from skin contact.
