Vermont Gage 112209540 Class Zz Minus Plug Pin Gage

Product Description

The VERMONT GAGE 112209540 is a Class ZZ Minus plug pin gage designed for precision dimensional inspection in industrial and metrology applications. The gage measures 9.54 mm in diameter with a tolerance of 0.00508 mm, making it suitable for NoGo inspection work where tight dimensional verification is required. Constructed from steel with a 10 microfinish surface coating, the 112209540 delivers consistent, repeatable measurements. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting quality system documentation requirements. Machinists, quality technicians, and tool room personnel use this type of gage to verify that a bored or reamed hole does not exceed its maximum allowable diameter.

This plug pin gage is used in manufacturing, inspection, and quality control environments where hole diameter verification is critical. The Class ZZ designation identifies it as a working-grade gage appropriate for production inspection. The Minus designation means the gage is manufactured to the lower end of the tolerance range, classifying it specifically as a NoGo member. It is also compatible with use alongside set micrometers, verniers, and other precision measuring devices for comparative measurement tasks in both job shop and high-volume production settings.

Compatibility

Designed for NoGo hole inspection applications and compatible with use alongside set micrometers, verniers, and other precision measuring devices as stated by the manufacturer.

Installation Notes

Plug pin gages are handled and used by quality technicians and machinists - no power source or mechanical installation is required. Keep gaging surfaces clean and lightly oiled when in storage to prevent corrosion on the steel body. Do not force the gage into a hole; apply only light, consistent hand pressure during inspection. Store in a protective case away from abrasive materials to maintain surface finish and measurement integrity.
