Vermont Gage 911217100 Class Zz Minus Plug Pin Gage

Product Description

The VERMONT GAGE 911217100 is a Class ZZ minus-tolerance plug pin gage used to verify bore diameters in precision inspection work. Measuring 0.1710 inches in diameter with a tolerance of 0.0002 inches, this gage is designed for NoGo inspection applications where confirming that a hole or bore does not exceed maximum material condition is critical. Machined from steel with a black oxide finish, the 911217100 comes with a Certificate of Accuracy traceable to NIST, making it suitable for quality control environments where documented traceability is required. Metrology technicians, machinists, and quality inspectors are the primary users.

This plug pin gage is used in dimensional inspection of drilled, reamed, or machined holes in manufacturing and production environments. The Class ZZ designation identifies it as a working-grade gage appropriate for shop-floor inspection and for setting micrometers, verniers, and other measuring devices. Its 2-inch overall length provides a comfortable grip for hand-held inspection tasks. It is well suited for both light production inspection and tool calibration support work across general machining and precision fabrication shops.

Compatibility

Designed for use in NoGo inspection applications and for setting micrometers, verniers, and other measuring devices requiring a 0.1710 inch reference diameter.

Installation Notes

Plug pin gages are handled and used by metrology technicians and quality control inspectors; no power tools or electrical shutoff is required. Keep the gage clean and lightly oiled when not in use to prevent corrosion and maintain measurement integrity. Do not force the gage into a bore; excessive insertion force can damage both the gage and the workpiece. Store in a protective case away from temperature extremes to preserve dimensional accuracy.
