Vermont Gage 112111980 Class Zz Plus Plug Gage 11.98 Mm

Product Description

The VERMONT GAGE 112111980 is a Class ZZ Plus plug gage designed for go inspection of machined bores and holes measuring 11.98 mm in diameter. Built from tool steel, this gage delivers a tolerance of 0.00508 mm and a 10 microfinish surface, making it well suited for verifying dimensional conformance in precision manufacturing environments. It ships with a Certificate of Accuracy that carries NIST traceability, meeting ASME B89.1 standards. Machinists, quality technicians, and metrology professionals use this gage in production inspection, toolroom verification, and calibration workflows.

This plug gage is applied in go inspection routines where a bore must accept the gage to confirm it has not been machined undersize. It is also used alongside set micrometers, verniers, and other measuring devices to verify and correlate dimensional readings. The 11.98 mm size fits a range of precision-toleranced holes commonly encountered in machined components, fixtures, and assemblies in both light manufacturing and heavy industrial settings.

Key Features

• Class ZZ Plus tolerance rating at 0.00508 mm for high-precision go inspection
• 10 microfinish surface finish minimizes gage wear and bore scoring
• Tool steel construction for durability under repeated production use
• Meets ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability
• Overall length of 2.0000 inches for standard handle compatibility

Compatibility

Designed for use with standard plug gage handles and suitable for go inspection applications with set micrometers, verniers, and other measuring devices as noted in the manufacturer specifications.

Installation Notes

Plug 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 on the tool steel surface. Never force the gage into a bore; go gages should enter under their own weight or with light hand pressure only. Store in the provided case or a clean, dry location to protect the precision-ground surface.
