Vermont Gage 112203940 Class Zz Minus Plug Pin Gage 3.94 Mm

Product Description

The VERMONT GAGE 112203940 is a Class ZZ Minus plug pin gage designed for precision dimensional inspection in machining and manufacturing environments. Manufactured from steel with a 10 microfinish surface coating, this pin gage measures 3.94 mm in diameter with a tolerance of 0.00508 mm, meeting Class ZZ minus specifications. At 2 inches in overall length and weighing 0.02 pounds, it is a compact, single-piece inspection tool. Each unit ships with a Certificate of Accuracy traceable to NIST standards, confirming calibration and measurement integrity for quality control documentation.

This pin gage is used in NoGo inspection applications, as well as for setting and verifying micrometers, verniers, and other precision measuring devices. It is well suited for incoming inspection stations, machine shop quality control, and tool room environments where verified dimensional reference is required. Machinists, quality technicians, and metrologists working in close-tolerance production settings will find this gage appropriate for daily inspection workflows where traceability and accuracy are mandatory.

Key Features

• Class ZZ Minus tolerance rating at 0.00508 mm for high-precision NoGo inspection
• Steel construction with 10 microfinish surface for consistent contact and wear resistance
• NIST-traceable Certificate of Accuracy included with each unit
• Compact 2-inch overall length suitable for bench or portable inspection use
• Single-piece design with no additional components required

Compatibility

Designed for use in NoGo inspection applications and for setting micrometers, verniers, and other precision measuring devices requiring a 3.94 mm diameter reference standard.

Installation Notes

This gage is handled and used by quality technicians and machinists in inspection environments, not installed in a mechanical system. Store the pin gage in its protective case when not in use to prevent surface damage or dimensional change. Clean contact surfaces before use to avoid measurement error from debris or oils. Do not force the pin into a bore; excessive insertion force can damage both the gage and the part being inspected.
