Vermont Gage 911200900 Class Zz Minus Plug Pin Gage

Product Description

The VERMONT GAGE 911200900 is a Class ZZ Minus plug pin gage with a 0.0090 inch diameter, manufactured from steel with a black oxide finish. This precision gage member is used to inspect bores and holes for NoGo tolerance limits, confirming that a feature does not exceed its maximum allowable size. The 911200900 measures 2 inches in overall length and carries a tolerance of 0.0002 inches. Each gage ships with a Certificate of Accuracy backed by NIST traceability, confirming the measurement standard used in calibration. Machinists, quality technicians, and metrology professionals rely on this type of gage for repeatable, standards-compliant inspection work in production and quality control environments.

This plug pin gage is suited for precision dimensional inspection applications in machine shops, manufacturing facilities, and quality labs. It is used alongside micrometers, verniers, and other measuring devices for NoGo inspection of very small diameter features. The 0.0090 inch diameter makes it appropriate for inspecting fine bores and holes where tight tolerances are critical to assembly and function. Its compact size and Class ZZ classification make it a standard choice for incoming inspection, in-process checks, and final acceptance gaging in close-tolerance manufacturing.

Key Features

• Includes Certificate of Accuracy with NIST traceability
• Compatible with micrometers, verniers, and standard measuring device setups

Compatibility

Designed for use with micrometers, verniers, and other measuring devices in NoGo inspection applications requiring a 0.0090 inch diameter plug pin gage.

Installation Notes

Plug pin gages are handled and used by quality technicians and metrology professionals. Handle the gage with clean cotton gloves or a clean cloth to prevent oils and contaminants from affecting measurement accuracy. Store in a protective case away from temperature extremes when not in use. Do not force the gage into a bore; resistance indicates the feature is at or within NoGo tolerance limits.
