Vermont Gage 111230400 Class Zz Minus Plug Pin Gage 0.3040 in

Product Description

The VERMONT GAGE 111230400 is a Class ZZ Minus plug pin gage used to perform NoGo inspection of precision bores and holes. Manufactured from steel with a 10 microfinish surface coating, it measures a diameter of 0.3040 inches with a tolerance of 0.0002 inches. At 2 inches in overall length, this pin gage is sized for handheld use in quality control and inspection workflows. Each unit ships with a Certificate of Accuracy that includes NIST traceability, making it suitable for use in calibrated inspection environments. Metrology technicians, machinists, and quality control inspectors rely on this gage to verify that a feature does not exceed its maximum material condition limit.

This pin gage is designed for NoGo inspection applications, confirming that a hole or bore diameter has not been machined oversize. It is also appropriate for setting and verifying micrometers, verniers, and other dimensional measuring devices. Typical use environments include machine shops, manufacturing floors, and inspection labs where precise hole tolerance verification is required. The NIST-traceable certificate supports compliance documentation in quality management systems.

Compatibility

Designed for NoGo inspection of precision bores and holes, and for setting micrometers, verniers, and other dimensional measuring devices requiring a 0.3040-inch reference diameter.

Installation Notes

Pin gages are installed and used by metrology technicians, quality control inspectors, and machinists. Clean both the gage and the feature being inspected before use to prevent debris from affecting measurement accuracy. Do not force the gage into a bore; Class ZZ Minus gages are intended to not enter a correctly sized NoGo feature. Store in a protective case when not in use to preserve the surface finish and dimensional integrity.
