Vermont Gage 112317270 Class Zz Plus Plug Gage 17.27mm

Product Description

The VERMONT GAGE 112317270 is a Class ZZ Plus plug gage machined from tool steel for dimensional inspection of bored holes and internal features. It measures 17.27 mm in diameter with a tolerance of 0.00508 mm, making it suited for high-repeatability Go inspection tasks. Overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documented quality-control workflows. Machinists, quality technicians, and tool-room inspectors use this gage to verify that a finished bore falls within its specified minimum-material condition before the part moves to the next operation.

This plug gage is used in production and inspection environments where bore diameter must be confirmed against a Go tolerance limit. Typical applications include verifying drilled, reamed, or honed bores in metal and rigid-plastic components. It is also used to calibrate or cross-check set micrometers, verniers, and other measuring devices as noted by the manufacturer. The 10 Micro coating finish helps resist wear during repeated insertions, extending service life in high-cycle inspection lines.

Compatibility

Designed for Go inspection of 17.27 mm diameter bores and as a reference standard for set micrometers, verniers, and other measuring devices, per manufacturer application data.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no permanent installation is required. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel body. Never force the gage into an undersized bore, as this damages both the gage and the workpiece. Store in the original protective case or a padded gage block tray away from temperature extremes to maintain calibration integrity.
