Vermont Gage 112111220 Class Zz Plus Plug Gage 11.22mm

Product Description

The VERMONT GAGE 112111220 is a Class ZZ Plus cylindrical plug gage with an 11.22 mm diameter, manufactured from tool steel and finished to a 10 microfinish surface. It is designed for go inspection applications where precise bore and hole verification is required. The gage carries a tolerance of 0.00508 mm and ships with a Certificate of Accuracy traceable to NIST, making it suitable for use in calibrated measurement programs. Overall length is 2.0000 inches. Licensed metrologists, quality technicians, and machinists install and use this gage in production and inspection environments where compliance with ASME B89.1 standards is required.

This plug gage is used in quality control and dimensional inspection settings across manufacturing, toolroom, and metrology lab environments. It is suited for verifying bore diameters in machined components as part of go inspection procedures, and for setting or checking micrometers, verniers, and other precision measuring devices. Its compact size and tool steel construction make it appropriate for both bench use and line inspection work.

Key Features

• Class ZZ Plus tolerance grade - 0.00508 mm tolerance for precision go inspection
• Tool steel construction for hardness and dimensional stability under repeated use
• 10 microfinish surface coating for consistent gage contact and wear resistance
• Includes Certificate of Accuracy with NIST traceability for calibration records
• Meets ASME B89.1 dimensional gage standards
• Overall length of 2.0000 inches for standard handle compatibility

Compatibility

Designed for go inspection of 11.22 mm diameter bores and for use with micrometers, verniers, and other precision measuring devices as stated by the manufacturer. Conforms to ASME B89.1 standards.

Installation Notes

Plug gages of this type are handled and used by quality technicians, metrologists, and machinists - not typically installed in a system but inserted manually into bores or used as a reference standard for measuring instruments. Clean the gage and the workpiece bore before use to prevent debris from affecting measurement accuracy or causing surface damage. Do not force the gage into a bore; excessive insertion force can damage both the gage and the workpiece. Store the gage in its protective case when not in use to preserve the ground surface finish and dimensional integrity.
