Vermont Gage 111116100 Class Zz Plus Plug Gage 0.161 in

Product Description

The VERMONT GAGE 111116100 is a Class ZZ Plus plug gage machined from tool steel for dimensional go inspection of bored holes, drilled passages, and precision-fit features. It measures a nominal diameter of 0.161 inches with a tolerance of 0.0002 inches and a surface finish of 10 microfinish, making it suitable for verifying hole acceptance in production and quality-control environments. The gage ships with a Certificate of Accuracy that carries NIST traceability, satisfying documentation requirements common in aerospace, automotive, and general manufacturing quality programs. Machinists, quality technicians, and metrology professionals are the typical end users.

This plug gage is used wherever a go-type functional check is needed on a 0.161-inch nominal hole. Typical applications include verifying hole size before assembly of close-tolerance pins, fasteners, or dowels. It is also suited for setting and confirming the calibration of micrometers, verniers, and other measuring devices. The overall length of 2.0 inches provides comfortable handling during bench inspection or in-process checks on the shop floor.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for precise go-inspection work
• 10 microfinish surface for accurate, repeatable contact with the workpiece bore
• Tool steel construction for wear resistance in production inspection use
• Meets ASME B89.1 standards for plain plug gages
• Includes Certificate of Accuracy with NIST traceability for quality documentation
• Overall length of 2.0 inches for stable, one-hand operation

Compatibility

Designed for go inspection of 0.161-inch nominal diameter holes and for use as a setting standard with micrometers, verniers, and other measuring devices, as specified by the manufacturer.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no power tools or utilities need to be de-energized before use. Keep the gage clean and lightly oiled when stored to prevent corrosion of the tool steel. Do not force the gage into an undersized hole, as this will damage the gage surface and invalidate its calibration. Periodic re-certification against NIST-traceable standards is recommended to maintain measurement integrity.
