Vermont Gage 112105980 Class Zz Plus Plug Gage 5.98mm

Product Description

The VERMONT GAGE 112105980 is a Class ZZ Plus plug gage designed for precision dimensional inspection in machine shops, quality labs, and manufacturing environments. With a nominal diameter of 5.98 mm and a tolerance of 0.00508 mm, this gage delivers the accuracy required for Go inspection work. The tool steel construction and 10 microfinish surface ensure consistent, reliable contact across repeated measurements. It carries a Certificate of Accuracy with NIST traceability and conforms to ASME B89.1 standards. Machinists, quality technicians, and metrologists rely on this type of gage to verify bore diameters and confirm that parts fall within specified tolerances.

This plug gage is suited for Go inspection applications where a bore must accept the gage to confirm minimum material condition. It is also compatible with setup and verification tasks involving set micrometers, verniers, and other precision measuring devices. At an overall length of 2.0000 inches, the gage handles comfortably for bench inspection or in-process checking on production floors. Typical users include quality control personnel and toolroom technicians working in precision machining, aerospace component inspection, and general metalworking environments.

Installation Notes

Plug gages are handled and applied by quality technicians and toolroom machinists, not installed in a traditional sense. Clean the gage and bore surfaces before use to prevent debris from affecting readings. Store the gage in its protective case when not in use to preserve the surface finish and dimensional accuracy. Periodic recalibration against traceable standards is recommended to maintain measurement integrity over time.
