Vermont Gage 111204800 Class Zz Minus Plug Pin Gage 0.0480 in

Product Description

The VERMONT GAGE 111204800 is a Class ZZ minus plug pin gage used to verify that a hole or bore does not exceed its maximum allowable size during NoGo inspection. Machined from steel with a 10 microfinish surface coating, this pin gage measures 0.0480 inches in diameter with a tolerance of 0.0002 inches. The overall length is 2 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for use in quality-controlled environments. Machinists, toolmakers, metrologists, and quality technicians rely on Class ZZ gages for go/nogo inspection tasks in production and calibration workflows.

This pin gage is designed for NoGo inspection applications where precise bore acceptance or rejection decisions are required. It also serves as a reference standard for setting micrometers, verniers, and other measuring devices. The 0.0480-inch diameter range is common in fine-tolerance work on small bores, pilots, and precision-machined features found in aerospace, medical device, and general manufacturing environments. The included NIST-traceable accuracy certificate supports ISO and AS9100 documentation requirements.

Key Features

• Class ZZ minus tolerance for NoGo inspection of bores and holes
• 0.0002-inch tolerance ensures precise dimensional verification
• 10 microfinish surface coating for consistent, accurate contact
• Steel construction for durability and dimensional stability
• Includes Certificate of Accuracy with NIST traceability
• Compatible with setting micrometers, verniers, and other measuring devices

Compatibility

Designed for use in NoGo bore inspection applications and for setting micrometers, verniers, and other precision measuring devices requiring a 0.0480-inch reference diameter.

Installation Notes

Handle pin gages with clean, dry hands or lint-free gloves to prevent corrosion and contamination of the gage surface. Store in a protective case away from other metal tooling to avoid nicks or dimensional damage. Clean the gage and the bore being inspected before use to ensure accurate readings. Periodic recalibration against NIST-traceable standards is recommended to maintain measurement integrity.
