Vermont Gage 111322050 Class Zz Plus Plug Gage 0.2205 in

Product Description

The VERMONT GAGE 111322050 is a Class ZZ Plus plug gage designed for precise go-type inspection of machined holes and bores. Built from tool steel to a 10 microfinish surface quality, this gage checks whether a hole falls within acceptable dimensional limits at a nominal diameter of 0.2205 inches with a tolerance of 0.0002 inches. It conforms to ASME B89.1 standards and ships with a Certificate of Accuracy traceable to NIST. Machinists, quality technicians, and toolroom personnel use plug gages like this one as a fast, reliable method to verify bore size without dedicated metrology equipment.

This gage is used in shop-floor inspection and quality control settings wherever hole diameter acceptance needs to be confirmed quickly. Common applications include go inspection of drilled, reamed, or bored holes in production machining environments. It is also suited for setting and verifying the calibration of micrometers, verniers, and other measuring devices where a known reference standard is needed. The 2.0-inch overall length provides comfortable handling during routine inspection tasks.

Key Features

• Class ZZ Plus tolerance grade with 0.0002 inch tolerance for accurate go inspection
• 10 microfinish surface finish for consistent gage contact and reduced wear
• Tool steel construction for durability in production and toolroom environments
• Conforms to ASME B89.1 dimensional standards
• Includes Certificate of Accuracy with NIST traceability
• Suitable for setting micrometers, verniers, and other measuring instruments

Compatibility

Designed as an OEM-style go plug gage for use with standard gage handle systems accepting gages at the 0.2205 inch nominal diameter range. Also functions as a reference standard for setting and verifying handheld measuring instruments.

Installation Notes

Plug gages are typically handled by quality technicians and machinists and do not require permanent installation. Store the gage in a protective case away from other metal tools to prevent surface damage and corrosion. Clean the gage and the bore being inspected before use to avoid false readings caused by debris or cutting fluid. Do not force the gage into a bore; excessive insertion force can damage the gage surface and compromise measurement accuracy.
