Vermont Gage 112407910 Class Zz Minus Plug Pin Gage 7.91mm

Product Description

The VERMONT GAGE 112407910 is a Class ZZ minus plug pin gage machined from steel and used to verify bore diameters in precision inspection work. It measures 7.91 mm in diameter with a tolerance of 0.00508 mm, making it suitable for NoGo inspection tasks where dimensional accuracy is critical. The overall length is 2 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, giving quality control and inspection personnel documented verification of the gage's conformance to Class ZZ minus standards. Machinists, quality technicians, and toolroom personnel use plug pin gages like this one during incoming inspection, in-process checks, and final part verification.

This gage is designed for NoGo inspection applications and is also suited for setting micrometers, verniers, and other measuring devices that require a traceable reference. It fits standard gage handle systems and is appropriate for use in machine shops, manufacturing facilities, and quality labs where tight bore tolerances must be confirmed. The 10 microfinish surface coating maintains gage accuracy and extends service life under regular inspection use.

Key Features

Compatibility

Designed for NoGo inspection use and for setting micrometers, verniers, and other precision measuring devices. Fits standard plug gage handle systems used in general toolroom and quality control applications.

Installation Notes

Plug pin gages should be handled with clean, dry hands or lint-free gloves to prevent contamination of the gage surface and bore being measured. Ensure the bore and gage are at the same ambient temperature before use to avoid measurement error due to thermal expansion. Store the gage in its protective case when not in use to preserve the surface finish and dimensional integrity. Inspection personnel should follow their facility calibration schedule to confirm ongoing NIST-traceable accuracy.
