Vermont Gage 101100300 Class Zz Plug Gage Set 240 Pc

Product Description

The VERMONT GAGE 101100300 is a Class ZZ plug gage set covering a diameter range of 0.011 to 0.25 inches across 240 pieces. Each gage is manufactured from steel and held to a plus tolerance of 0.0002 inches, meeting NIST traceable standards. The set is used by machinists, quality control technicians, and toolroom professionals to verify hole diameters, slot widths, and feature locations with repeatable accuracy. A Certificate of Accuracy with NIST traceability is included, supporting documentation requirements in ISO and AS9100 environments.

This set is suited for dimensional inspection work in manufacturing, toolroom, and quality lab settings. 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. The 240-piece range provides continuous coverage from very small bores at 0.011 inches up through 0.25 inches, making it a practical single-purchase solution for shops that work across a wide range of feature sizes.

Installation Notes

Plug gages are handled and stored by metrology or quality control personnel following standard gage care practices. Gages should be kept clean and lightly oiled when not in use to prevent corrosion. Always allow gages and workpieces to stabilize to the same ambient temperature before measuring to avoid thermal expansion errors. Do not force a plug gage into a feature; if resistance is encountered, verify the gage and bore are properly aligned and free of debris.
