Vermont Gage 101200200 Class Zz Plug Gage Set 50 Pc

Product Description

The VERMONT GAGE 101200200 is a Class ZZ plug gage set designed for precision hole measurement and inspection work. The set covers a diameter range of 0.011 to 0.060 inches and holds a minus tolerance of 0.000200 inches across all gages. Made from steel, these plug gages deliver the dimensional stability required for repeatable go and no-go gaging tasks. Each set ships with a Certificate of Accuracy that is NIST Traceable, supporting quality documentation requirements in production and inspection environments. Metrology technicians, machinists, and quality control personnel are the primary users of this tool.

This plug gage set is suited for inspection tasks in machine shops, manufacturing facilities, and toolrooms where tight-tolerance hole verification is required. Typical applications include measuring hole diameters, gaging slot widths and locations, calculating distances between holes, performing NO-GO gaging inspection, and setting micrometers, verniers, and other measuring devices. The 50-piece range provides continuous coverage from 0.011 to 0.060 inches, making the set practical for a broad variety of small-bore inspection jobs in both job-shop and production settings.

Compatibility

Designed as a standard Class ZZ plug gage set for use with any inspection or measurement workflow requiring hole diameter verification in the 0.011 to 0.060 inch range.

Installation Notes

Plug gages should be handled by qualified metrology or quality control personnel familiar with ASME gage tolerance standards. Store gages in the provided case and apply a light coat of instrument oil when not in use to prevent corrosion. Clean the gage and the workpiece bore before use to avoid false readings caused by debris or contamination. Do not force a plug gage into an undersized hole, as this can damage the gage land and affect calibration.
