Vermont Gage 111326450 Class Zz Plus Plug Gage 0.2645 in

Product Description

The VERMONT GAGE 111326450 is a Class ZZ Plus plug gage designed to measure bore and hole diameters to a nominal size of 0.2645 inches. Built from tool steel, it delivers a tolerance of 0.0002 inches and a 10 microinch surface finish, meeting the demanding accuracy requirements of production inspection environments. This gage is used to verify whether a feature falls within acceptable dimensional limits, making it a standard instrument in quality control workflows. It ships with a Certificate of Accuracy traceable to NIST, confirming calibration against recognized national standards. Typical users include machinists, quality technicians, and metrology professionals working to ASME B89.1 requirements.

This plug gage is suited for go inspection applications where precise hole or bore diameter verification is required. It is also used alongside set micrometers, verniers, and other measuring devices as a reference standard for calibration and setup. The 0.2645 inch nominal diameter and 2.0 inch overall length make it appropriate for use in precision machining shops, manufacturing quality labs, and inspection stations handling small-bore components. Each unit is packaged individually and is ready for immediate use upon receipt.

Key Features

• Class ZZ Plus tolerance grade: 0.0002 inches for high-accuracy go inspection
• 10 microinch surface finish for consistent, repeatable gage contact
• Tool steel construction for durability in production inspection use
• Conforms to ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability
• 2.0 inch overall length for practical handling in bench and in-line inspection

Compatibility

Designed for use in go inspection applications and as a reference standard for setting micrometers, verniers, and other measuring devices requiring a 0.2645 inch diameter reference.

Installation Notes

Plug gages should be handled and stored by qualified metrology or quality control personnel following standard gage-handling procedures. Clean the gage and the workpiece bore before use to prevent debris from affecting measurement accuracy or damaging the gage surface. Do not force the gage into an undersized hole, as this can damage the tool steel and introduce calibration error. Store in a protective case away from temperature extremes to maintain dimensional stability.
