Vermont Gage 111119100 Class Zz Plus Plug Gage 0.191 in

Product Description

The VERMONT GAGE 111119100 is a Class ZZ Plus plug gage designed for precision dimensional inspection of 0.191-inch diameter holes and bores. Manufactured from tool steel and finished to a 10 microfinish surface quality, this gage delivers a tolerance of 0.0002 inches, meeting the accuracy demands required in calibration and inspection environments. It is used by quality control technicians, machinists, and metrology professionals who need reliable, repeatable go-inspection measurements. Each unit ships with a Certificate of Accuracy backed by NIST traceability, confirming conformance to ASME B89.1 standards.

This plug gage is suited for go inspection applications in manufacturing and machine shop environments where bore size verification is required. It is also used to check and set micrometers, verniers, and other measuring devices to a known reference diameter. At 2.0 inches overall length, it fits standard gage handling and storage setups. Typical users include QC inspectors, tool room machinists, and calibration lab personnel working in both production and job-shop settings.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for high-accuracy go inspection
• 10 microfinish surface for smooth, consistent gage entry and minimal bore wear
• Tool steel construction for hardness and long service life in production use
• Conforms to ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability
• Overall length of 2.0 inches for standard single-end plug gage handling

Compatibility

Designed as an OEM-style Class ZZ Plus plug gage for go inspection of 0.191-inch nominal diameter bores, and for setting and verifying micrometers, verniers, and other precision measuring devices.

Installation Notes

Plug gages should be handled and stored by trained metrology or QC personnel following ASME B89.1 handling guidelines. Clean the gage and the bore being checked before use to prevent debris from affecting the measurement or damaging the gage surface. Do not force the gage into an undersized bore, as this can damage the precision-ground surface and invalidate the tool. Store in a protective case away from temperature extremes to maintain dimensional stability.
