Vermont Gage 111127200 Class Zz Plus Plug Gage 0.272 in

Product Description

The VERMONT GAGE 111127200 is a Class ZZ Plus plug gage designed for precision dimensional inspection of hole diameters. Built from tool steel with a 10 microfinish surface, this gage measures a nominal diameter of 0.272 inches with a tolerance of 0.0002 inches. It ships with a Certificate of Accuracy traceable to NIST, making it suitable for use in documented quality control environments. Licensed metrology technicians, machinists, and quality assurance personnel use this type of gage to verify bore dimensions during production or incoming inspection workflows.

This plug gage is used in go-inspection applications where confirming a hole meets its minimum acceptance diameter is required. It is also suited for setting and verifying micrometers, verniers, and other measuring devices that require a traceable reference standard. Typical applications include light manufacturing, tool rooms, and inspection labs where ASME B89.1 conformance is specified or expected.

Key Features

• Class ZZ Plus tolerance classification for go-inspection use
• 0.272 inches nominal measurement diameter
• 0.0002 inches tolerance for high-accuracy dimensional verification
• 10 microfinish surface finish for consistent contact and reduced wear
• Tool steel construction for durability in production environments
• Includes Certificate of Accuracy with NIST traceability per ASME B89.1

Compatibility

Designed as an OEM-style Class ZZ Plus plug gage for go-inspection of 0.272-inch nominal bore diameters, and for use as a reference standard with micrometers, verniers, and other calibrated measuring devices.

Installation Notes

Plug gages are handled and used by metrology technicians and quality assurance personnel, not installed in equipment. Store the gage in its protective case when not in use to prevent damage to the precision-ground surface. Avoid dropping or contacting the gage against hard surfaces, as impact can alter the calibrated diameter. Clean lightly with an appropriate instrument oil before use to prevent corrosion and ensure accurate contact.
