Vermont Gage 111193500 Class Zz Plus Plug Gage 0.935 in

Product Description

The VERMONT GAGE 111193500 is a Class ZZ Plus plug gage used for precise go inspection of machined bores and holes with a nominal diameter of 0.935 inches. Manufactured from tool steel with a 10 micro finish, this gage is designed to verify that a hole or bore meets its minimum size requirement during in-process or final inspection. The overall length is 2.0 inches, keeping the gage compact and easy to handle at the bench or on the floor. A Certificate of Accuracy with NIST Traceability is included, making it ready for use in documented quality systems without additional calibration steps. Tolerance is held to 0.0002 inches, consistent with ASME B89.1 standards.

This plug gage is suited for use in manufacturing, machine shop, and toolroom environments where bore tolerances must be confirmed before parts move to the next operation. Typical applications include go inspection of drilled, reamed, or bored holes in metalworking and precision machining contexts. It is also used to set and verify micrometers, verniers, and other measuring devices requiring a traceable reference standard. This gage is handled daily by quality technicians, machinists, and inspection personnel working to print tolerances.

Key Features

• Class ZZ Plus tolerance held to 0.0002 inches per ASME B89.1
• Tool steel construction with 10 micro surface finish for durability and accurate seating
• 0.935 inch measurement diameter for go inspection of matching bores
• Overall length of 2.0 inches for easy single-hand use
• Includes Certificate of Accuracy with NIST Traceability for quality documentation
• Suitable for setting micrometers, verniers, and other precision measuring instruments

Compatibility

Designed as a go plug gage for inspecting bores and holes nominally sized at 0.935 inches. Also suitable for setting and verifying micrometers, verniers, and other measuring devices requiring a traceable reference at this diameter.

Installation Notes

Plug gages are handled and used by quality technicians and machinists and do not require power or mechanical installation. Store the gage in its case when not in use to protect the precision ground surfaces from damage and corrosion. Clean the gage and the bore being checked before use to prevent debris from causing false readings or surface damage. Periodic recalibration against a traceable standard is recommended to maintain measurement integrity over time.
