Vermont Gage 901100200 Class Zz Plug Gage Set 50 Pc

Product Description

The VERMONT GAGE 901100200 is a 50-piece Class ZZ plug gage set designed for precision hole measurement and inspection work. Covering a diameter range of 0.011 to 0.060 inches, this set delivers a plus tolerance of 0.000200 inches per NIST Traceable standards. Each gage is manufactured from steel with a black oxide finish for corrosion resistance and easy size identification. Machinists, quality control technicians, and tool room professionals rely on Class ZZ plug gages for GO gaging inspection, verifying hole diameters, and calibrating measuring instruments. A Certificate of Accuracy with NIST Traceability is included with the set.

This set is suited for shop-floor and laboratory inspection environments where small-bore measurement accuracy is critical. Typical applications include calculating distances between holes, gaging slot widths and locations, measuring hole diameters in precision machined components, and setting micrometers, verniers, and other measuring devices. The 50-piece range makes this set practical for toolrooms and inspection departments handling a broad variety of small-diameter bores in a single kit.

Installation Notes

Plug gages are installed and used by quality control technicians and machinists in inspection environments. Handle gages with clean, dry hands or lint-free gloves to prevent contamination of the gage surface and protect calibration integrity. Store in the provided case when not in use to prevent surface damage. Periodic recalibration against NIST Traceable standards is recommended to maintain measurement accuracy over time.
