Vermont Gage 112105420 Class Zz Plus Plug Gage 5.42 Mm

Product Description

The VERMONT GAGE 112105420 is a Class ZZ Plus plug gage designed for dimensional inspection of machined bores and holes. It measures 5.42 mm in diameter with a tolerance of 0.00508 mm, making it suited for precision go inspection work where tight measurement confidence is required. Constructed from tool steel with a 10 microfinish surface, it delivers consistent, repeatable results in quality control environments. At 2.0000 inches overall length, it fits standard plug gage handles used in metrology labs, production floors, and machine shops. Each unit ships with a Certificate of Accuracy traceable to NIST.

This plug gage is used in go inspection applications to verify that a bore or hole meets minimum size requirements. It is compatible with standard gage handle systems and is suited for use alongside micrometers, verniers, and other precision measuring devices during incoming inspection, in-process checks, or final quality audits. Typical users include machinists, quality control technicians, and metrology professionals working to ASME B89.1 standards in industrial or manufacturing settings.

Compatibility

Designed for use with standard plug gage handles in go inspection applications alongside micrometers, verniers, and other precision measuring devices per ASME B89.1.

Installation Notes

This gage is handled and used by quality control technicians and metrology professionals rather than installed in a mechanical system. Store in a protective case away from moisture and temperature extremes to prevent dimensional drift in the tool steel. Clean contact surfaces with a lint-free cloth before use to avoid measurement error from debris or oil. Do not force the gage into an undersized bore, as this can damage both the gage and the workpiece surface.
