Vermont Gage 111402050 Class Zz Minus Plug Pin Gage 0.0205 in

Product Description

The VERMONT GAGE 111402050 is a Class ZZ Minus plug pin gage designed for precision dimensional inspection in manufacturing and metrology environments. Ground from steel with a 10 microfinish surface, this pin gage measures a nominal diameter of 0.0205 inches with a tolerance of 0.0002 inches. The minus designation means the gage is manufactured to the lower half of the Class ZZ tolerance band, making it suitable for NoGo inspection applications. Each unit ships with a Certificate of Accuracy traceable to NIST standards, supporting documented quality-control programs. Machinists, quality technicians, and toolroom professionals use this gage for go/no-go verification, setting micrometers, verniers, and other precision measuring devices.

This pin gage is used in precision inspection and quality assurance settings where sub-thousandth diameter verification is required. Typical applications include checking bore and hole diameters, setting comparators, and calibrating measuring instruments. The 0.0205-inch nominal diameter targets fine-bore and small-hole inspection common in aerospace, medical device, and precision machining environments. Its 2-inch overall length provides adequate handling clearance while keeping mass low for controlled measurement. The included NIST-traceable accuracy certificate makes this gage compatible with ISO and ANSI quality management documentation requirements.

• Suitable for setting micrometers, verniers, and other precision measuring devices

Compatibility

Designed for use in NoGo inspection applications and for setting micrometers, verniers, and other precision measuring devices requiring a 0.0205-inch reference diameter.

Installation Notes

Pin gages are handled and used by quality technicians and machinists in inspection environments. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Handle with clean, dry hands or cotton gloves to avoid transferring oils that can affect measurement accuracy. Never force the pin into a bore; apply only light axial pressure to avoid bending or surface wear that would compromise the tolerance specification.
