Vermont Gage 911202300 Class Zz Minus Plug Pin Gage 0.0230 in

Product Description

The VERMONT GAGE 911202300 is a Class ZZ Minus plug pin gage machined from steel with a black oxide finish, designed for precise dimensional inspection in tool rooms and quality control environments. The gage measures 0.0230 inches in diameter with a tolerance of 0.0002 inches, making it suitable for NoGo inspection applications where tight dimensional verification is required. Overall length is 2 inches. Each unit ships with a Certificate of Accuracy traceable to NIST standards. Machinists, toolmakers, and quality technicians use pin gages like this to verify bore diameters, hole sizes, and slot widths on production and inspection work.

This pin gage is used in NoGo inspection routines to confirm that a feature does not exceed its maximum material condition limit. It is also suited for setting micrometers, verniers, and other measuring devices that require a traceable reference standard. Typical applications include incoming inspection, in-process quality checks, and calibration setups in machine shops, manufacturing facilities, and metrology labs. The small 0.0230-inch diameter targets precision bores and fine holes found in precision-machined components.

Key Features

• Class ZZ Minus tolerance classification for NoGo inspection use
• 0.0230-inch diameter with a 0.0002-inch tolerance
• Steel construction with black oxide coating for corrosion resistance and reduced glare
• 2-inch overall length for easy handling in standard gage holders
• Includes Certificate of Accuracy with NIST traceability
• Compatible with setting micrometers, verniers, and other measuring devices

Compatibility

Designed for use in NoGo inspection applications and for setting micrometers, verniers, and other measuring devices requiring a traceable dimensional reference at 0.0230 inches diameter.

Installation Notes

Pin gages of this diameter are handled by quality technicians and toolroom personnel following standard metrology practices. Store in a protective case away from moisture and contaminants to preserve the black oxide finish and dimensional integrity. Avoid dropping or applying lateral force to the gage, as this can alter the geometry at this precision tolerance level. Reference ASME B89 standards for proper gage use and handling procedures.
