Vermont Gage 102400100 Class Zz Plug Gage Set 55 Pc

Product Description

The VERMONT GAGE 102400100 is a Class ZZ plug gage set designed for precision measurement of small-diameter holes and features. The set covers a diameter range of 0.210 mm to 1.29 mm with a minus 0.005 mm tolerance, making it suitable for high-accuracy inspection work in tool rooms, quality labs, and manufacturing environments. Constructed from steel, the 55-piece set includes a Certificate of Accuracy with NIST Traceable standards. Machinists, quality control technicians, and metrology professionals rely on this type of set for reliable go/no-go and dimensional inspection tasks.

This plug gage set is used in applications requiring precise measurement of very small hole diameters, slot widths, and hole locations. Typical use cases include setting micrometers, verniers, and other measuring devices, as well as performing NO-GO gaging inspection. The set is well-suited for precision machining shops, aerospace component inspection, medical device manufacturing, and other industries where tight dimensional tolerances must be verified. The NIST Traceable certification supports use in regulated quality systems and documented inspection processes.

Designed as an OEM-style plug gage set for use with standard gage handle holders compatible with the stated pin diameter range. No specific model compatibility was provided by the manufacturer for this set.

Installation Notes

Plug gages should be handled and stored by trained metrology or quality control personnel following established gage care procedures. Clean gages before and after use to prevent contamination that could affect accuracy. Do not force pins into holes, as this can damage the gage or the workpiece. Store the set in its case away from temperature extremes and humidity to preserve dimensional integrity.
