Vermont Gage 112204340 Class Zz Minus Plug Pin Gage 4.34 Mm

Product Description

The VERMONT GAGE 112204340 is a Class ZZ minus plug pin gage machined from steel and used to perform NoGo dimensional inspection on bored, drilled, and reamed holes. It measures 4.34 mm in diameter with a tolerance of 0.00508 mm, providing the tight dimensional control required for precision metrology work. The gage has an overall length of 2 inches and carries a 10 microfinish surface coating that protects the working surface and supports consistent, repeatable measurements. Each unit ships with a Certificate of Accuracy backed by NIST traceability. Machinists, quality technicians, and metrologists use this tool in production and inspection environments where go/nogo gage protocols are part of the quality plan.

This pin gage is sized for use in NoGo inspection applications and is compatible with standard gage handle systems. It is also suited for setting and verifying micrometers, verniers, and other measuring devices that require a known reference diameter. The 4.34 mm diameter fills a specific slot in metric inspection sets and is commonly used in both light manufacturing and precision machining shops where metric hole tolerances must be confirmed before parts advance to the next stage of production.

Key Features

• Class ZZ minus tolerance rating for NoGo inspection applications
• 4.34 mm diameter with 0.00508 mm tolerance for tight dimensional control
• Steel construction with 10 microfinish surface for durability and measurement consistency
• Includes Certificate of Accuracy with NIST traceability
• Compatible with standard gage handle systems and used to set micrometers and verniers
• Overall length of 2 inches fits common pin gage handle formats

Compatibility

Designed for use in NoGo inspection applications and as a reference standard for setting micrometers, verniers, and other measuring devices requiring a calibrated metric diameter reference.

Installation Notes

Pin gages are installed and handled by quality technicians and machinists following standard metrology practices. Clean the gage and the hole or device being checked before use to prevent debris from affecting the measurement. Store the gage in its protective case when not in use to avoid surface damage that could affect tolerance accuracy. Do not force the gage into a hole; a Class ZZ minus NoGo gage should not enter an in-tolerance hole.
