Vermont Gage 112400690 Class Zz Minus Plug Pin Gage

Product Description

The VERMONT GAGE 112400690 is a Class ZZ minus plug pin gage designed for precise small-bore inspection work. It measures a nominal diameter of 0.69 mm with a tolerance of 0.00508 mm, making it suitable for NoGo inspection applications where tight dimensional control is required. The gage is machined from steel and features a 10 microfinish surface coating for consistent contact and wear resistance. At 2 inches in overall length, it fits standard pin gage handles and is well suited for use alongside micrometers, verniers, and other precision measuring devices. Each unit ships with a Certificate of Accuracy with NIST Traceability.

This plug pin gage is used in quality control and inspection environments where small-bore hole acceptance or rejection must be verified against a dimensional standard. Typical applications include production inspection lines, toolroom verification, and setup confirmation for machined components with sub-millimeter bore requirements. It is appropriate for use in manufacturing, aerospace, automotive, and general precision machining shops where Class ZZ gage standards are called out on inspection plans or engineering drawings.

Installation Notes

Pin gages should be handled by calibration technicians or quality control personnel following established gage handling procedures. Store in a protective case away from moisture and temperature extremes to maintain dimensional integrity. Clean contact surfaces before use and avoid dropping or stacking with other metal tools that could affect the finish or calibration. Reference your facility calibration program and applicable ASME B89 standards for gage maintenance intervals.
