Vermont Gage 111138200 Class Zz Plus Plug Gage 0.382 in

Product Description

The VERMONT GAGE 111138200 is a Class ZZ Plus plug gage machined from tool steel and used to verify bore and hole dimensions to tight tolerances. With a measurement diameter of 0.382 inches and a tolerance of 0.0002 inches, this gage delivers reliable, repeatable dimensional inspection in shop and quality-control environments. The 10 microfinish surface finish minimizes wear on the gage and the workpiece during repeated use. Each unit ships with a Certificate of Accuracy with NIST traceability, supporting documented inspection processes and audit requirements.

This plug gage is suited for go inspection applications across manufacturing, machining, and precision fabrication settings. It is compatible with standard gage-handling workflows and is used alongside set micrometers, verniers, and other calibrated measuring devices. The 2.0-inch overall length provides a balanced, hand-held form factor for bench inspection or in-process checking. Typical users include quality technicians, machinists, and tool-room professionals working to ASME B89.1 standards.

Key Features

• Class ZZ Plus tolerance grade at 0.0002 inches for precise dimensional verification
• Tool steel construction for durability and dimensional stability under repeated use
• 10 microfinish surface finish reduces wear on gage and mating part
• NIST-traceable Certificate of Accuracy included for documentation and compliance
• Conforms to ASME B89.1 standards
• Compact 2.0-inch overall length for practical bench and in-process use

Compatibility

Designed for go inspection of bores and holes measuring 0.382 inches in diameter. Compatible for use with set micrometers, verniers, and other precision measuring devices as stated by the manufacturer.

Installation Notes

Plug gages are handled and applied by quality technicians or machinists during inspection routines, not installed in a system. Store the gage in its protective case when not in use to prevent damage to the ground surfaces. Clean the gage and the bore being inspected before use to avoid measurement errors caused by debris or contamination. Do not force the gage into an undersized bore, as this can damage both the gage and the workpiece.
