Vermont Gage 111280600 Class Zz Minus Plug Gage 0.806 in

Product Description

The VERMONT GAGE 111280600 is a Class ZZ minus plug pin gage machined to a nominal diameter of 0.8060 inches with a tolerance of 0.0002 inches. Built from steel with a 10 micro finish, this gage is used to verify that a hole or bore is within its specified maximum material condition limit. Class ZZ is the standard classification for workshop-grade go/no-go inspection tooling. Each unit ships with a Certificate of Accuracy backed by NIST traceability, confirming that the gage meets its stated tolerance at the time of manufacture. Overall length is 2 inches.

This plug pin gage is suited for NoGo inspection work in machine shops, manufacturing facilities, and quality control environments. It can also be used to set and verify micrometers, verniers, and other precision measuring devices. Technicians and quality inspectors use minus-tolerance plug gages to confirm that a hole has not been bored or reamed beyond its upper size limit, making this tool a standard part of in-process and final inspection routines.

Key Features

• Class ZZ minus tolerance: 0.0002 inches, suitable for general workshop inspection
• Nominal diameter of 0.8060 inches for precise hole and bore verification
• Steel construction with 10 micro surface finish for durability and measurement consistency
• 2-inch overall length provides handling stability in tight inspection setups
• NIST-traceable Certificate of Accuracy included with each gage
• Rated for NoGo inspection as well as setting micrometers, verniers, and comparable measuring instruments

Compatibility

Designed for use in NoGo hole inspection applications and for setting micrometers, verniers, and other precision measuring devices requiring a reference standard at 0.8060 inches diameter.

Installation Notes

Plug pin gages are handled and used by machinists, quality control inspectors, and metrologists. Before use, clean both the gage and the part bore with a lint-free cloth to remove chips, oil, or debris that could affect the reading. Never force a plug gage into a bore; light hand pressure is sufficient for a valid inspection result. Store the gage in its protective case when not in use to prevent surface damage and dimensional drift.
