Vermont Gage 901200200 Class Zz Plug Gage Set 50 Pc

Product Description

The VERMONT GAGE 901200200 is a 50-piece Class ZZ plug gage set designed for precision inspection of small-diameter holes and slots. Covering a range of 0.011 to 0.060 inches with a minus tolerance of 0.0002 inches (0.0002 mm), this set gives technicians and quality control personnel a reliable reference for verifying hole diameters and slot widths. The gages are finished in black oxide steel for corrosion resistance and durability in shop environments. A Certificate of Accuracy with NIST Traceable standards is included, supporting documented inspection programs and quality audits.

This set is suited for precision machining, toolroom, and quality assurance applications where small-bore measurement accuracy is critical. Typical uses 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 makes it a practical bench tool for shops working with tight-tolerance components across aerospace, automotive, medical, and general manufacturing environments.

Key Features

• Class ZZ tolerance rating with minus tolerance of 0.0002 inches for consistent GO/NO-GO inspection
• 50-piece set covers 0.011 to 0.060 inches diameter range in small increments
• Black oxide steel construction resists corrosion in production and toolroom settings
• NIST Traceable Certificate of Accuracy included for documented quality programs
• Supports multiple applications: hole diameter measurement, slot gaging, NO-GO inspection, and instrument calibration setup

Compatibility

Designed as an OEM-style precision measurement tool suitable for use with standard plug gage handles and fixtures accepting wire-type plug gages in the 0.011 to 0.060 inch diameter range.

Installation Notes

Plug gages are handled and used by quality technicians, machinists, and metrologists in inspection and toolroom settings. Store gages in the provided case and apply a light coat of instrument oil when not in use to prevent corrosion. Do not force a plug gage into an undersized hole, as this can damage the gage or alter its calibration. Gages should be recertified periodically per your facility quality management procedures.
