Vermont Gage 111157300 Class Zz Plus Plug Gage 0.573 in

Product Description

The VERMONT GAGE 111157300 is a Class ZZ Plus plug gage manufactured from tool steel for dimensional inspection of bored holes, drilled openings, and other internal features. With a measurement diameter of 0.573 inches, a tolerance of 0.0002 inches, and a 10 microinch surface finish, this gage delivers the precision required for Go inspection work. It comes with a Certificate of Accuracy with NIST traceability, confirming conformance to ASME B89.1 standards. Machinists, quality technicians, and tool-room personnel use this gage to verify that manufactured features fall within specified tolerances before parts advance through production or ship to customers.

This plug gage is suited for Go inspection applications in machine shops, manufacturing facilities, and quality-control environments. It is also used to calibrate and verify the accuracy of set micrometers, verniers, and other measuring devices. The 0.573-inch diameter and 2.0-inch overall length make it a practical hand-held tool for bench inspection or in-line process checks. The included Certificate of Accuracy with NIST traceability supports documentation requirements in ISO-regulated or AS9100-certified facilities.

Key Features

• 10 microinch surface finish for consistent, repeatable gage contact
• Tool steel construction for durability and wear resistance in shop environments
• Conforms to ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability for quality documentation
• Suitable for Go inspection and calibration of micrometers, verniers, and similar measuring devices

Compatibility

Designed for Go inspection of internal features measuring 0.573 inches in diameter, and for use as a reference standard with set micrometers, verniers, and other precision measuring devices.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no permanent installation is required. Keep the gage clean and lightly oiled when stored to prevent corrosion of the tool steel surface. Allow the gage and the workpiece to reach the same ambient temperature before measuring to avoid thermal expansion errors. Do not force the gage into an undersized feature, as this will damage both the gage and the part.
