Vermont Gage 112315670 Class Zz Plus Plug Gage 15.67mm

Product Description

The VERMONT GAGE 112315670 is a Class ZZ Plus plug gage manufactured from tool steel for dimensional inspection of bore and hole diameters. It measures a nominal diameter of 15.67 mm with a tolerance of 0.00508 mm (0.005 mm), making it well suited for Go inspection applications where tight dimensional verification is required. The gage has an overall length of 2.0000 inches and a finished coating of 10 Micro for wear resistance. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming calibration to ASME B89.1 standards. This tool is installed and used by machinists, quality technicians, and metrologists on the shop floor or in the inspection lab.

This plug gage is used in Go inspection routines to verify that a bore or hole meets its lower dimensional limit. It is appropriate for use with set micrometers, verniers, and other precision measuring devices as a reference or calibration standard. Typical applications include incoming inspection, in-process quality checks, and final part verification in manufacturing environments handling metric-dimensioned workpieces at or near 15.67 mm nominal diameter.

Compatibility

Designed for use as a Go plug gage in dimensional inspection setups involving set micrometers, verniers, and other precision measuring devices requiring a 15.67 mm nominal reference diameter.

Installation Notes

Plug gages should be handled by qualified quality or metrology personnel following shop calibration procedures. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel body. Do not force the gage into a bore; if resistance is felt during Go inspection, the bore is undersized. Store in the provided case or a protected location to maintain surface finish and calibration integrity.
