Vermont Gage 901100100 Class Zz Plug Gage Set 55 Pc

Product Description

The VERMONT GAGE 901100100 is a 55-piece Class ZZ plug gage set designed for precision hole and slot measurement in industrial inspection and quality control applications. The set covers a diameter range of 0.006 to 0.060 inches with a plus tolerance of 0.0002 inches, meeting NIST traceable standards. Each gage is manufactured from steel with a black oxide finish for corrosion resistance and long service life. A Certificate of Accuracy with NIST traceability is included, making this set suitable for documented inspection environments where measurement accountability is required.

This plug gage set is used in machine shops, tool rooms, and production inspection stations where technicians need to verify hole diameters, measure slot widths and locations, calculate distances between holes, and set or calibrate micrometers, verniers, and other precision measuring devices. The 55-piece range provides continuous coverage across the 0.006 to 0.060 inch diameter spectrum, reducing the need for individual gage procurement in small-bore inspection work. It is appropriate for both GO gaging inspection routines and general dimensional layout tasks.

Key Features

• Covers 0.006 to 0.060 inch diameter range in a single 55-piece set
• Steel construction with black oxide finish for durability and corrosion resistance
• Includes Certificate of Accuracy with NIST traceable calibration
• Suitable for GO gaging inspection, hole diameter measurement, slot gaging, and measuring device calibration
• NIST traceable standards compliance for documented quality control use

Compatibility

Designed for use as a precision inspection tool in applications requiring small-bore plug gaging from 0.006 to 0.060 inches, including GO gaging inspection, slot width verification, hole location measurement, and calibration of micrometers and vernier instruments.

Installation Notes

Plug gages are handled and used by machinists, quality control inspectors, and metrology technicians. Always clean and inspect each gage pin before use to avoid measurement error caused by debris or surface damage. Store the set in its case when not in use to protect the black oxide finish and gage accuracy. Do not force a plug gage into a hole; forcing can damage both the gage and the workpiece and will invalidate the measurement.
