Vermont Gage 111317750 Class Zz Plus Plug Gage 0.1775 in

Product Description

The VERMONT GAGE 111317750 is a Class ZZ Plus plug gage machined from tool steel for dimensional inspection of small-diameter bores and holes. It measures a nominal diameter of 0.1775 inches with a tolerance of 0.0002 inches, making it suitable for high-accuracy go inspection work. The gage features a 10 microfinish surface, which reduces wear on both the gage and the workpiece during repeated use. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming conformance to ASME B89.1 standards. Machinists, quality technicians, and tool-and-die tradespeople use this type of gage for fast, reliable bore acceptance checks on production and inspection floors.

This plug gage is suited for go inspection of precision bores in manufacturing and metrology environments. It is also used to calibrate and verify the accuracy of setting micrometers, verniers, and other measuring devices that require a certified reference. At 2.0 inches overall length, the 111317750 handles comfortably for bench inspection tasks. Typical applications include aerospace, automotive, and general metalworking shops where tight bore tolerances must be confirmed before parts advance to the next stage of production.

Key Features

• 10 microfinish surface reduces gage and workpiece wear during repeated use
• Tool steel construction provides hardness and dimensional stability
• Conforms to ASME B89.1 dimensional standards for plug gages
• Includes Certificate of Accuracy with NIST traceability
• Suitable for setting micrometers, verniers, and other precision measuring devices

Compatibility

Designed for go inspection of bores at a nominal diameter of 0.1775 inches. Also used as a reference standard for setting and verifying micrometers, verniers, and similar precision measuring instruments.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no installation in the traditional sense applies. Store the gage in its protective case when not in use to prevent nicks, corrosion, or dimensional changes. Clean the gage and the bore with a lint-free cloth before use to ensure accurate measurement. Do not force the gage into an undersized bore, as this can damage the gage surface and invalidate its calibration.
