Vermont Gage 112401630 Class Zz Minus Plug Pin Gage 1.63mm

Product Description

The VERMONT GAGE 112401630 is a Class ZZ Minus plug pin gage designed for precision dimensional inspection. Machined from steel with a 10 microfinish surface coating, this pin gage measures 1.63 mm in diameter and holds a tolerance of 0.00508 mm. At 2 inches in overall length, it is sized for bench use in quality control environments. Each unit ships with a Certificate of Accuracy traceable to NIST standards, making it suitable for documented inspection programs. Metrology technicians, machinist inspectors, and quality assurance personnel use this gage to verify hole diameters and confirm NoGo conditions in production and toolroom settings.

This pin gage is applied in NoGo inspection routines where a hole or bore must be confirmed as within tolerance. It is also used to set and verify micrometers, verniers, and other precision measuring devices. Typical applications include incoming inspection, in-process quality checks, and final acceptance testing in manufacturing environments handling tight-tolerance machined components. The Class ZZ designation indicates a commercial-grade tolerance class appropriate for general inspection work rather than master-gage applications.

Compatibility

Designed for use in NoGo hole inspection routines and as a setting reference for micrometers, verniers, and other precision measuring instruments requiring a 1.63 mm reference diameter.

Installation Notes

Pin gages are handled by metrology and quality control personnel and do not require mechanical installation. Store the gage in its protective case when not in use to prevent surface damage or contamination. Clean contact surfaces with a lint-free cloth before use to ensure accurate readings. Avoid dropping or forcing the gage into undersized features, as this can alter the ground surface and affect calibration.
