Vermont Gage 101200100 Class Zz Plug Gage Set 55 Pc

Product Description

The VERMONT GAGE 101200100 is a Class ZZ plug gage set designed for precision hole measurement and inspection across a diameter range of 0.006 to 0.06 inches. Built from steel with a minus tolerance of 0.000200 inches, this 55-piece set delivers the dimensional accuracy required for tight-tolerance inspection work. It ships with a Certificate of Accuracy that is NIST traceable, making it suitable for calibrated measurement environments. Machinists, quality technicians, and metrology professionals use sets like this when verifying bore diameters, slot widths, and hole-to-hole spacing on machined components.

This set is applied in manufacturing, machine shop, and quality control environments where small-diameter hole inspection is required. Typical uses include measuring hole diameters, calculating distances between holes, gaging slot widths and locations, performing NO-GO gaging inspection, and setting micrometers, verniers, and other measuring devices. The 55-piece configuration covers a continuous range from 0.006 to 0.06 inches, providing broad coverage for fine-diameter work in a single kit.

Key Features

• Class ZZ tolerance classification with a minus tolerance of 0.000200 inches for high-accuracy inspection
• Covers 0.006 to 0.06 inch diameter range in a 55-piece set
• Steel construction for durability and dimensional stability
• NIST traceable Certificate of Accuracy included with each set
• Supports multiple applications: hole diameter measurement, NO-GO gaging, slot width location, and instrument calibration setup

Compatibility

Designed as an OEM-style precision measurement set for use with standard plug gage handles and fixtures accepting wire-type gages in the 0.006 to 0.06 inch diameter range.

Installation Notes

Plug gages are handled and stored by quality technicians and metrology personnel following standard gage control procedures. Keep gages clean and lightly oiled when not in use to prevent corrosion and dimensional changes. Handle individual gage pins carefully to avoid dropping or bending, as steel pins in this diameter range are susceptible to deformation. Verify the Certificate of Accuracy is on file and traceable before placing the set into an active calibration or inspection program.
