Vermont Gage 111220100 Class Zz Minus Plug Pin Gage 0.2010 in

Product Description

The VERMONT GAGE 111220100 is a Class ZZ minus plug pin gage ground to a nominal diameter of 0.2010 inches with a tolerance of 0.0002 inches. It is used to verify hole and bore dimensions in production and quality-control environments. The steel construction and 10 microfinish surface ensure consistent, repeatable contact with the workpiece. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for documented inspection programs. Machinists, quality technicians, and precision toolroom personnel are the primary users of this type of gage.

This plug gage is designed for NoGo inspection applications, confirming that a hole or bore does not exceed its maximum allowable size. It is also used to set micrometers, verniers, and other comparative measuring devices to a known reference diameter. At 2 inches overall length, it fits standard gage handle setups and is appropriate for both bench inspection and floor-level production checks. Typical applications include light manufacturing, aerospace component verification, and precision machining shops where hole-tolerance conformance is required.

Key Features

• Class ZZ minus tolerance designation for NoGo inspection use
• 0.2010 inch nominal diameter with 0.0002 inch tolerance
• 10 microfinish surface for accurate, low-distortion contact
• Steel construction for durability and dimensional stability
• Certificate of Accuracy included with NIST traceability for audit-ready documentation
• 2 inch overall length compatible with standard pin gage handles

Compatibility

Designed for use in standard plug gage handle systems and as a reference setting tool for micrometers, verniers, and other measuring devices. Suitable for any NoGo inspection setup requiring a 0.2010 inch Class ZZ minus plug member.

Installation Notes

Pin gages should be inserted and withdrawn without lateral force to avoid wear on the gage or workpiece. Clean and lightly oil the gage before storage to prevent corrosion. Handle with clean, dry gloves or a lint-free cloth, as skin oils can affect dimensional accuracy over time. Calibration intervals should follow your facility quality plan and applicable measurement system standards.
