Vermont Gage 112115020 Class Zz Plus Plug Gage 15.02 Mm

Product Description

The VERMONT GAGE 112115020 is a Class ZZ Plus cylindrical plug gage designed for go inspection of machined bores and holes with a nominal diameter of 15.02 mm. Built from tool steel with a 10 microfinish surface coating, this gage delivers a tolerance of 0.005 mm, making it well suited for applications that demand tight dimensional verification. Each unit ships with a Certificate of Accuracy with NIST traceability, confirming the gage meets ASME B89.1 standards. Machinists, quality technicians, and metrology lab personnel use this type of gage as part of a standard go/no-go inspection process on production floors and inspection stations alike.

This plug gage is intended for go inspection use, confirming that a bore or hole meets its minimum size requirement before a part advances in the production process. It is also suitable as a reference standard for setting micrometers, verniers, and other measuring devices. With an overall length of 2.0 inches and a compact 0.16-pound weight, the 112115020 handles efficiently on a busy inspection bench. It is appropriate for both shop-floor dimensional checks and controlled metrology environments wherever 15.02 mm bore verification is required.

Key Features

• 10 microfinish surface coating for accurate, repeatable gage contact
• Tool steel construction for wear resistance in production inspection use
• Includes Certificate of Accuracy with NIST traceability
• Compatible as a reference standard for setting micrometers, verniers, and similar devices

Compatibility

Designed for go inspection of 15.02 mm diameter bores and as a setting standard for micrometers, verniers, and other measuring devices.

Installation Notes

Plug gages of this type are handled by quality technicians and machinists as part of dimensional inspection routines, not mechanical installation. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Handle with clean cotton gloves or a lint-free cloth to avoid contaminating the precision surface finish. Verify the gage is at ambient temperature before use, as thermal expansion can affect readings at this tolerance level.
