Vermont Gage 111172000 Class Zz Plus Plug Gage 0.72 in

Product Description

The VERMONT GAGE 111172000 is a Class ZZ Plus plug gage designed for precise hole diameter inspection in machining and metrology applications. It measures a nominal diameter of 0.72 inches with a tolerance of 0.0002 inches, making it suitable for go-inspection work where tight dimensional control is required. Manufactured from tool steel, the gage features a 10 microinch surface finish that supports repeatable, accurate contact with the workpiece. Each unit ships with a Certificate of Accuracy with NIST traceability, confirming conformance to ASME B89.1 standards. Licensed inspectors, machinists, and quality technicians use this tool as part of a calibrated measurement program.

This plug gage is used in manufacturing environments where hole diameter verification is part of an inspection routine. It is suited for go-inspection of bored, drilled, or reamed holes at the 0.72-inch nominal size. It is also used to set and verify micrometers, verniers, and other measuring devices in dimensional calibration setups. The 2.0-inch overall length provides a manageable grip for hand-held inspection on the shop floor or in a quality lab. Typical users include machinists, toolroom technicians, and quality control inspectors in industrial production settings.

Compatibility

Designed for go-inspection of 0.72-inch nominal diameter holes and for use as a setting standard with micrometers, verniers, and other measuring devices in dimensional inspection programs.

Installation Notes

Plug gages are handled and used by qualified machinists or quality technicians; no installation in the traditional sense applies. Store the gage in its protective case when not in use to prevent nicks or surface damage that would affect accuracy. Clean the gage and the workpiece hole before use to remove chips, oil, or debris. Never force the gage into a hole; apply only light, consistent hand pressure to avoid damaging the gage or the part being checked.
