Vermont Gage 101200600 Class Zz Plug Gage Set 125 Pc

Product Description

The VERMONT GAGE 101200600 is a Class ZZ plug gage set covering a diameter range of 0.501 to 0.625 inches in 125 individual pieces. Each gage is manufactured from steel and held to a minus tolerance of 0.0002 inches, making this set suitable for precision inspection work where tight dimensional control is required. A Certificate of Accuracy with NIST Traceable calibration documentation is included, supporting quality-system requirements in regulated shop environments. Metrology technicians, quality control inspectors, and toolroom machinists use sets like this to verify hole diameters and validate measuring instruments to a known standard.

This plug gage set is designed for production and inspection environments where a wide range of hole sizes must be verified consistently. Typical applications include measuring hole diameters, performing NO-GO gaging inspection, checking slot widths and locations, calculating distances between holes, and setting micrometers, verniers, and other measuring devices to a reference dimension. The 125-piece range provides continuous coverage from 0.501 to 0.625 inches, reducing the need to source individual gages across that span.

Compatibility

Designed as a general-purpose Class ZZ plug gage set for use with standard gage handles and holders accepting plug-style gage blanks in the 0.501 to 0.625 inch diameter range.

Installation Notes

Plug gages are precision instruments and should be handled by qualified metrology or quality control personnel. Store gages in the provided case or a dedicated gage storage solution to prevent surface damage and corrosion. Clean gages and the workpiece bore before use to ensure accurate readings. Do not force a gage into an undersized hole, as this will damage the gage and may yield inaccurate measurements.
