Vermont Gage 111229700 Class Zz Minus Plug Pin Gage 0.2970 in

Product Description

The VERMONT GAGE 111229700 is a Class ZZ Minus plug pin gage machined to a nominal diameter of 0.2970 inches with a tolerance of 0.0002 inches. It is a go/no-go style inspection tool used to verify bore and hole dimensions to a known standard. The gage is 2 inches in overall length and is manufactured from steel with a 10 microfinish surface coating. Each unit ships with a Certificate of Accuracy traceable to NIST standards. Dimensional inspection professionals and machinists use this gage to validate precision measurements on the shop floor or in a quality-control environment.

This pin gage is suited for NoGo inspection applications and is also used to calibrate or verify micrometers, verniers, and other measuring devices. It fits into standard-practice dimensional inspection workflows in manufacturing, tooling, and metrology environments. The Class ZZ designation indicates a commercial-grade tolerance class appropriate for general-purpose inspection work where high-volume part checking is required.

Compatibility

Designed for use in NoGo bore inspection applications and for setting or verifying micrometers, verniers, and other dimensional measuring devices requiring a 0.2970-inch reference standard.

Installation Notes

This gage is handled and used by dimensional inspection technicians, machinists, and quality-control personnel. Clean the gage and mating bore or measuring device thoroughly before use to prevent measurement error from debris or surface contamination. Store the gage in its protective case when not in use to preserve the surface finish and dimensional integrity. Do not force the gage into a bore; use light, consistent hand pressure to avoid damage to the gage or the workpiece.
