Vermont Gage 112208980 Class Zz Minus Plug Pin Gage 8.98mm

Product Description

The VERMONT GAGE 112208980 is a Class ZZ Minus plug pin gage machined from steel for precise bore and hole inspection. It measures a nominal diameter of 8.98 mm with a tolerance of 0.00508 mm, providing the tight dimensional control required for NoGo inspection work. The overall length is 2 inches. Each gage ships with a Certificate of Accuracy traceable to NIST, confirming that the part meets its stated tolerance before it ever reaches a workbench. Machinists, quality technicians, and tool-room professionals use this type of gage as a fast, reliable go/no-go check during in-process and final inspection.

This plug gage is suited for inspecting bored holes, drilled passages, and machined features where a NoGo member is needed to confirm that a hole has not been oversized beyond its allowable tolerance. It is also used as a setting standard for micrometers, verniers, and other measuring devices that require a traceable reference. Typical environments include machine shops, production lines, and inspection labs handling precision components in both low-volume and high-volume settings.

Compatibility

Designed for NoGo inspection use and as a setting reference for micrometers, verniers, and other precision measuring devices, as stated by the manufacturer.

Installation Notes

Plug pin gages are handled and used by quality technicians and machinists - no permanent installation is required. Keep the gage clean and lightly oiled when not in use to prevent corrosion. Never force a plug gage into a hole; if resistance is felt, remove the gage and re-inspect the workpiece. Store in a protective case away from heat sources and abrasive materials to maintain calibration integrity.
