Vermont Gage 112308830 Class Zz Plus Plug Gage 8.83mm

Product Description

The VERMONT GAGE 112308830 is a Class ZZ Plus plug gage used to verify bore diameters and hole tolerances in precision inspection work. Manufactured from tool steel with a 10 microfinish surface coating, this gage delivers consistent, repeatable measurements at an 8.83 mm nominal diameter and a tolerance of 0.00508 mm. It is used for go inspection applications and as a reference standard when setting micrometers, verniers, and other measuring devices. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming conformance to ASME B89.1 standards. Dimensional metrology technicians, quality control inspectors, and tool-room professionals use this gage in both production and calibration environments.

This plug gage is suited for precision inspection in manufacturing, machine shops, and quality assurance labs where bore diameter verification is required. At 8.83 mm diameter and an overall length of 2.0000 inches, it fits standard gage handle holders commonly used in industrial inspection setups. The Class ZZ Plus designation indicates a tighter tolerance grade appropriate for production go inspection of close-tolerance bored and drilled features. Applications include checking finished holes in metal, plastic, and composite workpieces prior to assembly.

Installation Notes

Plug gages should be handled by qualified inspection or metrology personnel following established quality control procedures. Clean the gage and the bore being measured before use to prevent debris from affecting readings or damaging the gage surface. Store the gage in its protective case when not in use and keep it away from temperature extremes that could affect dimensional accuracy. Periodic recalibration against traceable standards is recommended to maintain measurement integrity.
