Vermont Gage 112220260 Class Zz Minus Plug Pin Gage 20.26 Mm

Product Description

The VERMONT GAGE 112220260 is a Class ZZ Minus plug pin gage machined from steel and used to verify hole diameters in NoGo inspection applications. It measures a nominal diameter of 20.26 mm with a tolerance of 0.00508 mm, providing the precision required for dimensional quality control on the shop floor or in the inspection lab. Each gage ships with a Certificate of Accuracy that includes NIST traceability, confirming the measurement standard behind every reading. The overall length is 2 inches, keeping the gage compact for use in tight setups. Machinists, quality control technicians, and metrology professionals are the primary users of this type of precision tooling.

This pin gage is suited for NoGo inspection tasks where confirming that a bore or hole does not exceed a maximum allowable diameter is required. It is also used alongside set micrometers, verniers, and other measuring devices for calibration and verification routines in manufacturing, tooling, and general metrology environments. The Class ZZ designation indicates a standard commercial-grade tolerance class appropriate for general inspection work rather than master-grade or laboratory-reference applications.

Key Features

• 20.26 mm nominal measurement diameter for precise bore inspection
• Class ZZ Minus tolerance class at 0.00508 mm for reliable NoGo gauging
• Steel construction for durability and dimensional stability
• Includes Certificate of Accuracy with NIST traceability
• 2-inch overall length for compact handling in various setups
• Compatible with set micrometers, verniers, and standard measuring instruments

Compatibility

Designed for use in NoGo inspection routines and as a setting reference for micrometers, verniers, and other measuring devices in standard shop and quality control environments.

Installation Notes

Pin gages are handled and used by quality control technicians and machinists following standard metrology practices. Keep the gage clean and lightly oiled when not in use to prevent corrosion and protect the ground surface finish. Do not force the gage into a bore; light hand pressure is the correct technique to avoid damage to the gage or the workpiece. Store in the original case or protective sleeve to maintain dimensional integrity.
