Vermont Gage 111324450 Class Zz Plus Plug Gage 0.2445 in

Product Description

The VERMONT GAGE 111324450 is a Class ZZ Plus plug gage machined from tool steel for precision dimensional inspection. It measures shaft and hole diameters at 0.2445 inches with a tolerance of 0.0002 inches and a 10 microfinish surface finish. This gage is used to verify whether a feature falls within acceptable Go limits, making it a standard tool in quality control and inspection environments. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming calibration to ASME B89.1. Machinists, quality technicians, and metrology professionals use this gage as a reliable reference for Go inspection work.

This plug gage is suited for inspecting bored holes, drilled passages, and machined features in both production and tool-room environments. Its 2.0-inch overall length provides a practical handling size for bench inspection setups. The 10 microfinish surface finish minimizes wear on contact surfaces and supports repeatable measurements. It is also appropriate for use in setting and verifying micrometers, verniers, and other measuring devices that require a known reference diameter.

Key Features

• Class ZZ Plus tolerance grade with 0.0002-inch tolerance for precise Go inspection
• 0.2445-inch diameter measurement range
• 10 microfinish surface finish for low wear and consistent contact
• Tool steel construction for durability in production inspection environments
• NIST-traceable Certificate of Accuracy included with each unit
• Manufactured to ASME B89.1 standards

Compatibility

Suitable for Go inspection of 0.2445-inch nominal diameter features. Also used to set and verify micrometers, verniers, and other measuring devices requiring a calibrated reference diameter.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no installation in the traditional sense applies. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Avoid dropping or striking the gage, as impact can alter the ground surfaces and invalidate calibration. Clean contact surfaces with a lint-free cloth before and after each use to maintain measurement integrity.
