Vermont Gage 112409970 Class Zz Minus Plug Pin Gage 9.97mm

Product Description

The VERMONT GAGE 112409970 is a Class ZZ Minus plug pin gage designed for precision dimensional inspection in manufacturing and metrology environments. Machined from steel with a 10 microfinish surface coating, this pin gage measures 9.97 mm in diameter with a tolerance of 0.00508 mm, making it suitable for high-accuracy NoGo inspection tasks. The overall length is 2 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming it meets Class ZZ Minus standards. Machinists, quality technicians, and metrology professionals use this gage to verify bore and hole dimensions against specified limits.

This pin gage is intended for NoGo inspection applications, where it confirms that a hole or bore does not exceed the maximum allowable size. It is also used to set and verify micrometers, verniers, and other measuring devices requiring a traceable reference. Typical use environments include precision machine shops, quality control labs, and production inspection stations handling close-tolerance metalwork. The gage is sized and toleranced for applications where a 9.97 mm reference is required in the minus-class range.

Compatibility

Designed for NoGo inspection use and for setting micrometers, verniers, and other measuring devices requiring a 9.97 mm Class ZZ Minus reference standard.

Installation Notes

Pin gages are handled and stored by metrology technicians and quality control personnel. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel surface. Do not force the gage into a bore; apply only light, consistent hand pressure to avoid measurement error or surface damage. Store in the provided case or a protective holder away from temperature extremes to maintain dimensional stability.
