Vermont Gage 911109900 Class Zz Plus Plug Gage 0.099 in

Product Description

The VERMONT GAGE 911109900 is a Class ZZ Plus plug gage machined to a 0.099 inch nominal diameter with a tolerance of 0.0002 inches. Built from tool steel with a black oxide finish, this gage is designed for Go inspection work, verifying that a drilled, reamed, or bored hole meets the minimum acceptable size before a part moves to the next stage. It ships with a Certificate of Accuracy traceable to NIST, confirming the gage meets ASME B89.1 dimensional standards. Machinists, quality technicians, and tool room personnel use this type of gage as a fast, reliable attribute check on the production floor or in the inspection lab.

This plug gage is suited for Go inspection of small-diameter bores in precision machined components. It is also used to calibrate and verify the accuracy of micrometers, verniers, and other measuring devices. The 0.099 inch diameter targets small bore applications common in aerospace, automotive, medical device, and general precision manufacturing environments. The 2.0 inch overall length provides enough handle for controlled insertion and withdrawal without introducing measurement error from misalignment.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for precise Go inspection of small bores
• Tool steel construction for wear resistance and dimensional stability
• Black oxide finish reduces surface corrosion and light reflection during inspection
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 dimensional standards
• Compact 2.0 inch overall length suited for bench and in-process inspection

Compatibility

Designed for Go inspection of 0.099 inch nominal diameter bores and for use as a reference standard with micrometers, verniers, and other precision measuring devices.

Installation Notes

Plug gages are handled and used by quality technicians and machinists performing dimensional inspection. Clean the gage and the bore with a lint-free cloth before each use to prevent debris from affecting the reading. Never force the gage into a bore; Go gages should pass under the weight of the gage alone or with light hand pressure. Store the gage in its protective case when not in use to prevent surface damage and maintain calibration integrity.
