Vermont Gage 111307750 Class Zz Plus Plug Gage 0.0775 in

Product Description

The VERMONT GAGE 111307750 is a Class ZZ Plus plug gage designed for precision go inspection of machined bores and holes at 0.0775 inches in diameter. Built from tool steel with a 10 microfinish surface, it delivers consistent, repeatable measurement results in shop-floor and quality-control environments. The gage measures 2.0 inches in overall length and holds a tolerance of 0.0002 inches, making it suitable for verifying tight-tolerance work. A Certificate of Accuracy with NIST traceability is included, supporting calibration records and inspection documentation. Machinists, quality technicians, and tool-room professionals are the primary users of this type of gage.

This plug gage is used in manufacturing and machine shop settings to verify that bored, drilled, or reamed holes meet specified diameter requirements before assembly. It is also used to set and verify micrometers, verniers, and other measuring devices, making it a versatile reference standard in dimensional inspection workflows. The go configuration confirms that a hole has been produced to minimum acceptable size. It is well suited for both production-line inspection and bench-top gauge calibration tasks in facilities that maintain documented quality systems.

Compatibility

Designed for go inspection of machined holes and bores at 0.0775 inches in diameter, and for use as a reference standard when setting micrometers, verniers, and other dimensional measuring devices.

Installation Notes

Plug gages are handled and used by machinists and quality control technicians and do not require power-down procedures. Store the gage in its protective case when not in use and avoid dropping or striking it, as impact can alter calibration. Clean the gage and the bore being checked before use to prevent debris from affecting readings. Recalibrate or verify against a traceable standard at intervals consistent with your facility quality program.
