Vermont Gage 112208960 Class Zz Minus Plug Pin Gage 8.96 Mm

Product Description

The VERMONT GAGE 112208960 is a Class ZZ minus plug pin gage designed for precise dimensional inspection of bores and holes at 8.96 mm diameter. Built from steel with a 10 microfinish surface coating, this gage is used to verify that a hole or bore does not fall below the minimum acceptable size, making it a NoGo inspection tool. It carries a tolerance of 0.00508 mm, meeting Class ZZ specifications for general-purpose inspection work. Each unit ships with a Certificate of Accuracy backed by NIST traceability. Overall length is 2 inches. Metrology technicians, machinists, and quality control personnel are the primary users of this type of gage.

This pin gage is applied in NoGo inspection routines where a bore or hole must be confirmed as within tolerance. It is also suited for setting and verifying micrometers, verniers, and other measuring devices requiring a traceable reference standard. Typical environments include machine shops, manufacturing quality labs, tool rooms, and precision assembly operations. The 8.96 mm diameter targets metric bore tolerancing applications common in component manufacturing and incoming inspection workflows.

Key Features

• Class ZZ minus tolerance of 0.00508 mm for general-purpose NoGo inspection
• Steel construction with 10 microfinish surface coating for consistent contact and durability
• NIST-traceable Certificate of Accuracy included with each unit
• 2-inch overall length for standard plug gage handling and ergonomics
• Suitable for setting micrometers, verniers, and other calibrated measuring devices

Compatibility

Designed for use as a NoGo plug pin gage in metric bore inspection applications and as a reference standard for setting micrometers, verniers, and other measuring devices requiring a traceable 8.96 mm diameter reference.

Installation Notes

Plug pin gages are handled and applied by metrology technicians and quality control personnel following standard gauging practices. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel body. Do not force the gage into a bore; a NoGo gage should not enter a conforming hole, and forced insertion can damage both the gage and the part. Store in a controlled environment away from temperature extremes to maintain dimensional stability and calibration integrity.
