Vermont Gage 111191600 Class Zz Plus Plug Gage 0.916 in

Product Description

The VERMONT GAGE 111191600 is a Class ZZ Plus plug gage used to verify hole diameters in precision inspection and quality control applications. Machined from tool steel, this plug gage measures a diameter of 0.916 inches with a tolerance of 0.0002 inches and a 10 microinch surface finish. It is designed for Go inspection tasks, confirming that a bore or hole meets minimum acceptable size. The part comes with a Certificate of Accuracy with NIST Traceability, supporting documentation requirements in calibrated inspection environments. Dimensional inspection technicians, machinists, and quality control personnel are the primary users of this tool.

This plug gage is suited for use in machine shops, manufacturing facilities, and metrology labs where close-tolerance bore inspection is required. It is also used to set and verify micrometers, verniers, and other measuring devices to a known reference diameter. The 0.916-inch measurement diameter fits applications requiring inspection in that specific size range. Conformance to ASME B89.1 standards makes this gage appropriate for both production floor and laboratory inspection environments.

Compatibility

Designed for Go inspection of 0.916-inch diameter bores and for use as a reference standard when setting micrometers, verniers, and other dimensional measuring devices.

Installation Notes

Plug gages are handled and used by dimensional inspection technicians and machinists; no installation in the traditional sense applies. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Do not force the gage into an undersized bore, as this can damage the gage or the workpiece. Store in a protective case away from impact, heat sources, and contaminants to maintain calibration integrity.
