Vermont Gage 112209340 Class Zz Minus Plug Pin Gage 9.34mm

Product Description

The VERMONT GAGE 112209340 is a Class ZZ Minus plug pin gage machined from steel and used to perform NoGo inspection of precision bored holes and machined features. The gage measures 9.34 mm in diameter and holds a tolerance of 0.00508 mm, meeting the dimensional requirements for Class ZZ minus fits. Each unit ships with a Certificate of Accuracy that carries NIST traceability, confirming the gage has been verified against national standards. The 10 microfinish surface coating protects the gage surface and reduces wear during repeated insertion checks. Machinists, quality technicians, and tool-room professionals use this type of gage as part of a systematic go/no-go inspection routine on production and inspection floors.

This pin gage is suited for inspecting holes, bores, and other precision features where a 9.34 mm NoGo limit must be verified. It is also used with set micrometers, vernier calipers, and other measuring devices that require a known-dimension reference. The Class ZZ designation places it in the general-purpose inspection category, appropriate for standard tolerance work in manufacturing, maintenance, and quality control environments. The overall length of 2 inches provides adequate reach for most standard inspection applications.

Compatibility

Designed for use in NoGo hole inspection applications and as a reference with set micrometers, vernier calipers, and other precision measuring devices requiring a 9.34 mm diameter reference standard.

Installation Notes

Pin gages are handled and stored by quality technicians and tool-room professionals. Always clean the gage and the feature being inspected before use to avoid false readings caused by debris or burrs. Store the gage in its case or on a gage stand away from sources of heat and corrosion. Do not force the gage into a feature; resistance indicates the NoGo condition has been met.
