Vermont Gage 112416170 Class Zz Minus Plug Pin Gage 16.17mm

Product Description

The VERMONT GAGE 112416170 is a Class ZZ Minus plug pin gage machined from steel and used to perform NoGo inspection of precision bored holes and internal diameters. It measures 16.17 mm in diameter with a tolerance of 0.00508 mm, making it suited for high-accuracy go/no-go gauging workflows in tool rooms, machine shops, and quality-control environments. Each unit ships with a Certificate of Accuracy that carries NIST traceability, confirming the gage meets documented dimensional standards. The overall length is 2 inches. Machinists, quality technicians, and metrologists use this class of gage to verify that a manufactured bore does not exceed its maximum allowable size.

Class ZZ Minus plug pin gages are a standard tool in dimensional inspection stations wherever tight hole tolerances must be verified quickly and reliably. This gage is appropriate for use with micrometers, verniers, and other calibrated measuring devices when establishing reference or confirming instrument calibration. It fits standard gage handle sets and is equally at home on a production floor or in a dedicated metrology lab. The 10 micro coating and finish helps resist wear and maintain surface integrity during repeated insertions.

Compatibility

Designed for NoGo inspection use with micrometers, verniers, and other calibrated measuring devices. Fits standard plug gage handles accepting 16.17 mm diameter pin gages.

Installation Notes

Plug pin gages are handled and used by machinists and quality technicians - no special tools or power sources are required. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel body. Do not force the pin into a bore; controlled hand pressure is the correct insertion method to avoid damaging the gage or the workpiece. Store the gage in its protective case away from temperature extremes to preserve dimensional accuracy.
