Vermont Gage 111123000 Class Zz Plus Plug Gage 0.23 in

Product Description

The VERMONT GAGE 111123000 is a Class ZZ Plus plug gage designed for precise hole and bore inspection in dimensional metrology applications. This go-style gage measures 0.23 inches in diameter and holds a tolerance of 0.0002 inches, making it suitable for verifying tight-tolerance features in manufactured parts. Constructed from tool steel with a 10 microfinish surface, it delivers consistent, repeatable results across routine inspection tasks. A Certificate of Accuracy with NIST Traceability is included, supporting quality management and audit documentation requirements. Machinists, quality technicians, and tool-room professionals rely on this type of gage for fast, reliable pass-fail inspection.

This plug gage is used in manufacturing and machine shop environments where hole diameter conformance must be verified to close tolerances. It is appropriate for inspecting drilled, reamed, or bored holes in production and incoming inspection settings. The gage is also referenced when calibrating or setting micrometers, verniers, and other measuring devices. It suits both job-shop and high-volume production quality control workflows where ASME B89.1 compliance is required.

Key Features

• Class ZZ Plus tolerance grade — 0.0002 inches tolerance for precise go-style inspection
• 0.23 inch measurement diameter in a compact 2.0 inch overall length
• Tool steel construction for durability and wear resistance in production environments
• 10 microfinish surface for consistent contact and repeatable readings
• Includes Certificate of Accuracy with NIST Traceability for documentation and audit compliance
• Meets ASME B89.1 dimensional gage standards

Compatibility

Designed as an OEM-style go plug gage for use with standard gage handle sets and applicable to inspection of 0.23 inch diameter holes per ASME B89.1 requirements. Also suitable for setting micrometers, verniers, and other measuring devices as stated by the manufacturer.

Installation Notes

Plug gages are handled and used by quality technicians and machinists — no power source or mechanical installation is required. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Clean the gage and the workpiece bore before each use to ensure accurate contact. Calibration intervals should follow your facility quality management system procedures and applicable metrology standards.
