Vermont Gage 111165600 Class Zz Plus Plug Gage 0.656 in

Product Description

The VERMONT GAGE 111165600 is a Class ZZ Plus plug gage designed for go inspection of bored, reamed, and drilled holes at a nominal diameter of 0.656 inches. Manufactured from tool steel with a 10 microinch surface finish, this gage delivers a tolerance of 0.0002 inches, meeting ASME B89.1 standards for dimensional verification. At an overall length of 2.0 inches, it is sized for easy single-hand operation on the bench or at the machine. Each unit ships with a Certificate of Accuracy with NIST traceability, satisfying quality system documentation requirements in production and inspection environments.

This plug gage is used in manufacturing and metrology settings where go inspection of internal features is required. It is suited for verifying holes produced by drilling, reaming, or boring operations and serves as a reference standard for setting micrometers, verniers, and other measuring devices. Machinists, quality technicians, and tool room personnel typically use this type of gage during in-process and final inspection of machined components in both job shop and production floor environments.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no power source or trade licensing is required for use. Store the gage in its protective case when not in use and avoid contact with abrasive surfaces to preserve the precision ground finish. Clean the gage shank and the workpiece bore before each inspection pass to prevent false readings or surface damage. Calibration intervals should follow your facility quality plan and applicable ASME B89.1 guidance.
