Vermont Gage 111159800 Class Zz Plus Plug Gage 0.598 in

Product Description

The VERMONT GAGE 111159800 is a Class ZZ Plus plug gage designed for precision dimensional inspection of machined bores and holes. Manufactured from tool steel with a 10 microinch surface finish, this gage measures a nominal diameter of 0.598 inches and holds a tolerance of 0.0002 inches. It ships with a Certificate of Accuracy traceable to NIST, making it suitable for applications where documented measurement traceability is required. Machinists, quality technicians, and metrology professionals use this gage as a reliable go-inspection tool to verify that bored features conform to specified tolerances.

This plug gage is intended for go inspection tasks in manufacturing and quality control environments. It is compatible with applications involving the verification of drilled, reamed, or bored holes where tight dimensional control is critical. It is also suited for use alongside set micrometers, verniers, and other precision measuring devices that require a traceable reference standard. Typical environments include machine shops, production floors, and inspection labs working to ASME B89.1 standards.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for high-accuracy go inspection
• 10 microinch surface finish for consistent, repeatable contact
• Tool steel construction for durability in production environments
• Meets ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability for documented quality systems
• Overall length of 2.0 inches for easy handling and integration with standard gage handles

Compatibility

Designed for go inspection of holes and bores at 0.598 inches nominal diameter. Compatible for use with set micrometers, verniers, and other precision measuring devices as a reference standard per the supplier application data.

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 not in use to prevent corrosion of the tool steel surface. Always allow the gage and the workpiece to thermally stabilize to the same ambient temperature before inspection to avoid measurement error. Store in the provided case or a protected location to prevent nicking or surface damage that would affect accuracy.
