Vermont Gage 112200720 Class Zz Minus Plug Pin Gage 0.72mm

Product Description

The VERMONT GAGE 112200720 is a Class ZZ Minus plug pin gage designed for precision dimensional inspection in industrial and metrology applications. This single-end pin gage checks hole diameters to a tolerance of 0.00508 mm, making it suitable for NoGo inspection work where tight dimensional control is required. Constructed from steel with a 10 microfinish surface coating, the gage measures 0.72 mm in diameter and has an overall length of 2 inches. Each unit ships with a Certificate of Accuracy backed by NIST traceability, confirming calibration to a recognized national standard. Metrologists, quality technicians, and precision machinists use this gage in production and inspection environments.

This pin gage is used in NoGo inspection applications to verify that a hole or bore does not exceed its maximum allowable diameter. It is also suited for setting and checking micrometers, verniers, and other measuring devices that require a traceable reference standard. Typical use cases include incoming inspection, in-process quality control, and calibration lab work across manufacturing, aerospace, and precision machining environments. The 0.72 mm diameter targets very small bore and hole features common in precision assemblies and instrument components.

Compatibility

Designed for use as a NoGo inspection gage and as a reference standard for setting micrometers, verniers, and other precision measuring devices requiring a traceable dimensional reference at 0.72 mm.

Installation Notes

This gage is handled and used by quality technicians and metrologists in inspection and calibration settings. Store the gage in its protective case when not in use to prevent damage to the precision ground surface. Clean contact surfaces before use to avoid measurement errors caused by debris or contamination. Handle with clean gloves or a lint-free cloth to prevent corrosion from skin oils on the steel surface.
