Vermont Gage 112417670 Class Zz Minus Plug Pin Gage 17.67mm

Product Description

The VERMONT GAGE 112417670 is a Class ZZ Minus tolerance plug pin gage machined from steel for dimensional inspection work. It measures bores and holes at a nominal diameter of 17.67 mm with a tolerance of 0.00508 mm, making it suitable for NoGo inspection applications where tight, repeatable measurements are required. The overall length is 2 inches. Each gage ships with a Certificate of Accuracy that carries NIST traceability, giving quality technicians and metrology staff documented confidence in the gage's calibration. Installers, machinists, and quality control personnel in manufacturing and precision-fabrication environments rely on this type of gage for go/no-go inspection routines.

This plug pin gage is intended for NoGo inspection use, as well as for setting and verifying micrometers, verniers, and other measuring devices that require a known reference diameter. It fits standard inspection workflows in machine shops, manufacturing cells, and quality labs where bore tolerances must be confirmed before parts advance in the production process. The 10 micro coating and finish helps maintain surface integrity and gage accuracy over repeated use cycles.

Compatibility

Designed for use in NoGo inspection applications and as a reference standard for setting micrometers, verniers, and comparable precision measuring devices requiring a 17.67 mm reference diameter.

Installation Notes

Plug pin gages are handled and used by quality technicians and metrologists in inspection environments. Clean the gage and the bore or device being checked before use to prevent measurement error from debris or contamination. Store in a protective case away from temperature extremes to preserve calibration. Do not force the gage into an undersized bore, as this can damage the gage surface and compromise accuracy.
