Vermont Gage 111155200 Class Zz Plus Plug Gage 0.552 in

Product Description

The VERMONT GAGE 111155200 is a Class ZZ Plus plug gage designed for precision dimensional inspection of bore and hole diameters. Manufactured from tool steel, this plug gage holds a diameter of 0.552 inches with a tolerance of 0.0002 inches and a 10 microinch surface finish. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting the requirements of ASME B89.1. Metrology technicians, quality control inspectors, and machinists rely on this type of gage for reliable go inspection decisions at the bench or on the shop floor.

This plug gage is suited for go inspection tasks in manufacturing and quality assurance environments, both light industrial and precision machining settings. It is used with set micrometers, verniers, and other measuring devices to verify bore and hole diameter conformance. The 0.552-inch nominal diameter and 2.0-inch overall length make it compatible with standard gage-handle holders used in typical incoming, in-process, and final inspection workflows.

• Includes Certificate of Accuracy with NIST traceability, conforming to ASME B89.1
• Compatible with go inspection, set micrometers, verniers, and other measuring devices
• 2.0-inch overall length fits standard plug gage handles

Compatibility

Designed for use in go inspection applications and with set micrometers, verniers, and other measuring devices as stated by the manufacturer. Fits standard gage handles accepting a 0.552-inch diameter plug member.

Installation Notes

Plug gages of this type are handled and used by quality control inspectors and metrology personnel. Before use, clean the gage and mating bore with a lint-free cloth to remove oils and debris that can affect measurement accuracy. Store the gage in its protective case when not in use to prevent surface damage. Do not use this gage as a forcing tool or apply side load during inspection, as this can alter the gage member or damage the part being checked.
