Vermont Gage 111205600 Class Zz Minus Plug Pin Gage 0.0560 in

Product Description

The VERMONT GAGE 111205600 is a Class ZZ Minus plug pin gage machined from steel and used to perform NoGo inspection of precision bored holes and internal features. At 0.0560 inches in diameter, this pin gage helps technicians, machinists, and quality control inspectors verify that a feature does not exceed its maximum material condition. The minus tolerance designation means the gage is ground to the lower end of the Class ZZ tolerance band, which is 0.0002 inches, making it suited for go/no-go gauging workflows where tight dimensional control is required. Each unit ships with a Certificate of Accuracy traceable to NIST standards.

This pin gage is used in manufacturing, metrology, and maintenance environments where small-diameter hole inspection is part of quality assurance. Typical applications include setting micrometers, verifying verniers, and calibrating other measuring devices in addition to direct hole inspection. The 2-inch overall length provides a practical grip length for use in hand gauging without a handle, though it is compatible with standard pin gage handle sets. It is commonly used in machine shops, tool rooms, and production floor inspection stations.

Key Features

• Class ZZ Minus tolerance ground to 0.0002 inches for NoGo inspection applications
• 0.0560-inch diameter for inspection of small precision bored features
• Steel construction for durability and dimensional stability during repeated use
• 10 microfinish surface coating for accurate seating and consistent contact
• Includes Certificate of Accuracy with NIST traceability for calibration documentation
• 2-inch overall length fits standard pin gage handle sets

Compatibility

Designed for use in NoGo hole inspection applications and for setting micrometers, verniers, and other precision measuring devices requiring a 0.0560-inch reference diameter.

Installation Notes

Pin gages should be handled with clean, dry gloves or a lint-free cloth to prevent corrosion from skin contact. Before use, inspect the gage for nicks, burrs, or surface damage that could produce false readings. When inserting into a bore, apply light hand pressure only — never force the pin — to avoid damaging the gage or the workpiece. Store in a protective case away from temperature extremes to maintain dimensional stability.
