Vermont Gage 111156500 Class Zz Plus Plug Gage 0.565 in

Product Description

The VERMONT GAGE 111156500 is a Class ZZ Plus plug gage machined from tool steel to a 0.565-inch diameter with a tolerance of 0.0002 inches and a 10 microinch surface finish. It is used to verify bore and hole dimensions in manufactured parts, confirming whether a workpiece falls within acceptable size limits for go inspection. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting the documentation requirements of quality-controlled production and inspection environments. Machinists, quality control technicians, and toolroom professionals use this gage as part of standard dimensional verification workflows on the shop floor or in the inspection lab.

This plug gage is suited for go inspection checks on holes, bores, and other cylindrical features measuring 0.565 inches in diameter. It is also appropriate for setting and calibrating micrometers, verniers, and other precision measuring devices that require a traceable reference standard. At 2.0 inches overall length, it handles conveniently in bench-top inspection setups. It is intended for use in manufacturing, machining, and quality assurance operations where ASME B89.1 compliance is required.

Key Features

• 0.565-inch measurement diameter with 0.0002-inch tolerance for precise go inspection
• 10 microinch surface finish for consistent, repeatable contact with the workpiece
• Tool steel construction for durability and dimensional stability under regular shop use
• Includes Certificate of Accuracy with NIST traceability, supporting ISO and quality audit requirements
• Manufactured to ASME B89.1 standards for dimensional gaging
• 2.0-inch overall length provides a practical, easy-to-handle form factor

Compatibility

Designed for go inspection of 0.565-inch diameter holes and bores, and for use as a setting reference with micrometers, verniers, and other precision measuring devices per ASME B89.1.

Installation Notes

Plug gages are handled and used by quality control technicians and machinists — no installation in the traditional sense is required. Store the gage in its protective case when not in use to prevent surface damage and dimensional drift. Do not force the gage into a bore; excessive insertion force can damage both the gage and the workpiece, and can introduce measurement error. Allow the gage and workpiece to reach the same ambient temperature before inspection, as thermal expansion affects dimensional readings at tight tolerances.
