Vermont Gage 112402050 Class Zz Minus Plug Pin Gage 2.05mm

Product Description

The VERMONT GAGE 112402050 is a Class ZZ Minus plug pin gage machined from steel and used to verify bore and hole dimensions in precision inspection workflows. The gage measures a nominal diameter of 2.05 mm with a tolerance of 0.00508 mm, providing the close control required for NoGo inspection applications. At 2 inches in overall length, it is sized for handheld use in toolroom and shop-floor environments. Each unit ships with a Certificate of Accuracy traceable to NIST standards, making it suitable for documented quality-control processes. Machinists, quality technicians, and toolroom inspectors are the primary users of this type of precision gage.

This pin gage is intended for NoGo inspection tasks where a bore or hole must be confirmed as not oversized beyond a specified tolerance. It is also suited for setting micrometers, verniers, and other comparative measuring devices that require a traceable reference. Typical applications include incoming inspection, in-process quality checks, and final acceptance testing in precision machining, manufacturing, and metrology environments. The Class ZZ classification indicates a commercial-grade tolerance appropriate for production inspection rather than laboratory-grade master gage work.

Key Features

• Class ZZ Minus tolerance designation for NoGo inspection applications
• 2.05 mm nominal diameter with 0.00508 mm tolerance for precise fitment verification
• Steel construction with 10 microfinish surface coating for accurate contact and wear resistance
• 2 inch overall length suits handheld inspection use
• Includes Certificate of Accuracy with NIST traceability for documented quality programs

Compatibility

Designed for use in NoGo bore inspection, and as a reference standard for setting micrometers, verniers, and other measuring devices requiring a traceable plug gage reference.

Installation Notes

Pin gages are handled and used by quality technicians and toolroom machinists and do not require mechanical installation. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel surface. Do not force the gage into a bore; forced insertion can damage both the gage and the workpiece. Store individually or in a protective sleeve to preserve the surface finish and dimensional integrity.
