Vermont Gage 111220200 Class Zz Minus Plug Pin Gage

Product Description

The VERMONT GAGE 111220200 is a Class ZZ minus plug pin gage designed for precision dimensional inspection in machining and metrology applications. Built from steel with a 10 microfinish coating, this pin gage measures a nominal diameter of 0.2020 inches with a tolerance of 0.0002 inches. At 2 inches in overall length, it is sized for easy single-hand use in bench or in-process inspection work. Each unit ships with a Certificate of Accuracy with NIST traceability, confirming its calibration chain for quality-controlled environments. Machinists, tool and die makers, and quality technicians rely on plug pin gages like this to verify bore and hole diameters quickly and reliably.

This pin gage is used in NoGo inspection routines where a go/no-go determination is needed for hole acceptance. It is also applicable for setting micrometers, verniers, and other measuring devices to a known reference diameter. Typical use cases include production floor inspection, incoming quality control, and tool calibration in both job shop and high-volume manufacturing environments. Its Class ZZ minus designation means the gage tolerance is held on the minus side of nominal, making it appropriate for NoGo member applications per standard plug gage practice.

Compatibility

Designed for use in NoGo plug gage inspection routines and for setting micrometers, verniers, and other measuring devices requiring a 0.2020 inch reference diameter.

Installation Notes

Plug pin gages are handled and used by machinists, quality technicians, and metrologists. Clean the gage and the workpiece bore before use to prevent debris from affecting the measurement. Do not force the gage into a hole; apply only light, controlled hand pressure to avoid wear or damage to the gage surface. Store the gage in its case or protective sleeve when not in use to preserve the surface finish and dimensional integrity.
