Vermont Gage 112401350 Class Zz Minus Plug Pin Gage 1.35 Mm

Product Description

The VERMONT GAGE 112401350 is a Class ZZ Minus plug pin gage designed for precise dimensional inspection at 1.35 mm diameter. This steel pin gage holds a tolerance of 0.00508 mm and is manufactured to Class ZZ Minus standards, making it suitable for NoGo inspection applications. The overall length is 2 inches. Each unit ships with a Certificate of Accuracy that carries NIST traceability, supporting quality documentation requirements in calibration labs, inspection departments, and production floor environments. Machinists, metrologists, and quality technicians use this type of gage to verify that a hole or bore does not exceed its maximum allowable size.

This plug pin gage is used in NoGo inspection routines where the gage must not pass through a conforming feature. It is also appropriate for setting micrometers, verniers, and other measuring devices that require a traceable reference standard. Typical applications include incoming inspection, in-process quality control, and calibration of hand measuring tools across manufacturing, tooling, and metrology environments. The 10 microfinish surface coating supports consistent, repeatable contact during gage use.

Installation Notes

Pin gages are handled and stored by quality technicians and metrologists following shop metrology procedures. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel surface. Do not force the gage into a feature; Class ZZ Minus gages are intended to check maximum material condition and should not pass a conforming hole. Store in the original case or a dedicated gage block tray to protect the precision ground surface.
