Vermont Gage 112317890 Class Zz Plus Plug Gage 17.89mm

Product Description

The VERMONT GAGE 112317890 is a Class ZZ Plus plug gage designed for precision dimensional inspection of bored holes and machined features at 17.89 mm diameter. It is manufactured from tool steel with a 10 micro finish and holds a tolerance of 0.00508 mm, meeting ASME B89.1 standards. Each unit ships with a Certificate of Accuracy with NIST traceability, making it a reliable reference tool for quality control environments. Machinists, tool-and-die technicians, and metrology professionals use this gage to verify go-condition acceptance in production and inspection workflows.

This plug gage is suited for go inspection of holes at 17.89 mm nominal diameter. It is used with micrometers, verniers, and other measuring devices to confirm dimensional compliance during first-article inspection, in-process checks, or final QC. The overall length of 2.0000 inches accommodates standard handle systems and gage holders commonly found in machine shops and inspection departments handling medium-diameter work.

Installation Notes

Plug gages should be handled and stored by trained metrology or inspection personnel following ASME B89.1 guidelines. Clean the gage and the workpiece bore before use to prevent debris from affecting readings or damaging the gage surface. Never force the gage into a bore; apply only light, consistent hand pressure consistent with standard go-gage practice. Store in the supplied case or a clean, protected environment to preserve the calibrated surface finish.
