Vermont Gage 111134400 Class Zz Plus Plug Gage 0.344 in

Product Description

The VERMONT GAGE 111134400 is a Class ZZ Plus plug gage designed for precise go inspection of 0.344-inch diameter bores and holes. Built from tool steel with a 10 microfinish surface, this gage delivers a tolerance of 0.0002 inches, making it suitable for dimensional verification tasks where tight measurement confidence is required. It ships with a Certificate of Accuracy bearing NIST traceability, meeting ASME B89.1 standards. Machinists, quality technicians, and metrologists use this gage to confirm that machined features fall within specified limits before parts move to the next stage of production or assembly.

This plug gage is used in quality control and inspection environments across manufacturing, tool rooms, and machine shops. Its primary application is go inspection of 0.344-inch diameter features, and it is also suited for setting and verifying micrometers, verniers, and other measuring devices. The compact 2.0-inch overall length makes it easy to handle in bench inspection setups or at the machine. It is appropriate for both production-floor spot checks and lab-grade measurement verification.

Compatibility

Designed for go inspection of 0.344-inch diameter bores and for use with micrometers, verniers, and other measuring devices requiring a traceable reference standard.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no mechanical installation is required. Store the gage in its case when not in use to protect the precision-ground surface from damage or contamination. Clean the gage and the feature being checked before use to prevent debris from affecting measurement accuracy. Handle with clean cotton or nitrile gloves to avoid transferring oils that can affect surface finish and gage life.
