Vermont Gage 102200100 Class Zz Plug Gage Set 55 Pc

Product Description

The VERMONT GAGE 102200100 is a Class ZZ plug gage set designed for precision hole measurement and inspection work in manufacturing and metrology environments. The set covers a diameter range of 0.2 to 1.28 mm with a minus tolerance of 0.005 mm, making it suitable for close-tolerance inspection tasks. Constructed from steel, this 55-piece set is used by quality control technicians, machinists, and tool room professionals who require reliable, repeatable measurement in small-bore applications. Each set ships with a Certificate of Accuracy traceable to NIST standards.

This plug gage set is applied in precision machining and inspection settings where small hole diameters must be verified to tight tolerances. Typical uses include verifying hole diameters, checking slot widths and locations, calculating distances between holes, performing NO-GO gaging inspection, and setting micrometers, verniers, and other measuring devices. The 55-piece range makes it well suited for shops and inspection departments that work regularly with small-diameter features across a variety of workpiece types.

Compatibility

Designed for use as a general-purpose Class ZZ plug gage set in precision inspection and metrology applications involving small-bore hole diameters from 0.2 to 1.28 mm.

Installation Notes

Plug gages should be handled by qualified metrology or quality control personnel familiar with ASME gage standards. Store gages in their case when not in use to prevent damage to precision ground surfaces. Clean measuring surfaces before and after each use to maintain accuracy. Avoid dropping or applying lateral force to gage pins, as this can alter calibration.
