Vermont Gage 101300400 Class Zz Plug Gage Set 190 Pc

Product Description

The VERMONT GAGE 101300400 is a 190-piece Class ZZ plug gage set designed for precision dimensional inspection and measurement tasks in machine shops, quality labs, and manufacturing environments. The set covers a range of 0.0615 to 0.2505 inches with a plus tolerance of 0.0002 inches per gage. Each gage is manufactured from steel and ships with a Certificate of Accuracy that is NIST traceable, making this set suitable for formal inspection processes and calibration workflows. Metrology technicians, machinists, and quality control professionals are the primary users of this type of tooling.

This plug gage set is used wherever precise hole diameter verification is required. Typical applications include GO gaging inspection, measuring hole diameters, gaging slot widths and locations, calculating distances between holes, and setting micrometers, verniers, and other measuring devices to known reference values. The 190-piece range provides broad coverage across the stated diameter range, reducing the need for multiple individual gages in a mixed-production environment. It is well suited to both production floor inspection and metrology lab use.

Installation Notes

Plug gages should be handled and stored according to standard metrology practices to prevent corrosion, nicking, or dimensional change. Clean gages and the workpiece bore before use to ensure accurate readings. Do not force a gage into an undersized hole. Periodic recalibration against NIST traceable standards is recommended to maintain measurement integrity.
