Vermont Gage 112202520 Class Zz Plug Pin Gage 2.52 Mm

Product Description

The VERMONT GAGE 112202520 is a Class ZZ Minus plug pin gage machined from steel and designed for precise dimensional inspection of bored holes, drilled features, and machined openings. The gage measures 2.52 mm in diameter with a tolerance of 0.00508 mm, providing the close measurement control required for NoGo inspection work. At 2 inches in overall length, the pin is sized for easy single-hand use in production and quality-control environments. Each unit ships with a Certificate of Accuracy that carries NIST traceability, meeting documentation requirements for calibrated inspection tooling in regulated shop and lab settings.

This pin gage is suited for quality inspection applications in machine shops, toolrooms, and manufacturing facilities where dimensional verification of small bored features is required. It is used alongside set micrometers, verniers, and other precision measuring devices to verify that a feature does not exceed its maximum allowable size. The Class ZZ Minus designation indicates the gage falls on the minus side of nominal, making it appropriate for NoGo inspection per standard plug gage practice. Machinists, quality technicians, and metrologists are the typical end users.

Key Features

• 2.52 mm diameter with a 0.00508 mm tolerance for high-precision NoGo inspection
• Steel construction for durability and dimensional stability in shop environments
• 10 Microfinish surface coating for accurate, repeatable contact with measured bores
• 2-inch overall length for comfortable, controlled single-hand operation
• Includes NIST-traceable Certificate of Accuracy for calibration records and quality documentation
• Class ZZ Minus classification suitable for use with set micrometers, verniers, and other measuring devices

Compatibility

Designed for NoGo inspection use with set micrometers, verniers, and other standard precision measuring devices where a 2.52 mm diameter Class ZZ Minus plug pin gage is specified.

Installation Notes

Pin gages are handled by quality technicians and machinists and require no permanent installation. Store the gage in its protective case when not in use to prevent surface damage that could affect measurement accuracy. Clean the gage and the bore to be inspected before use to remove chips, coolant, or debris. Never force a pin gage into a feature; excessive insertion force can damage both the gage and the workpiece.
