Vermont Gage 111123100 Class Zz Plus Plug Gage 0.231 in

Product Description

The VERMONT GAGE 111123100 is a Class ZZ Plus plug gage designed for dimensional inspection of machined bores and holes at a nominal diameter of 0.231 inches. Built from tool steel, this go-inspection gage carries a tolerance of 0.0002 inches and a 10 microfinish surface finish. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. It is intended for use by machinists, quality technicians, and tool-room professionals who require repeatable, standards-backed dimensional verification in production or inspection environments.

This plug gage is used in go-inspection applications to verify that a machined hole or bore falls within its specified tolerance. It is also appropriate as a reference standard for setting micrometers, verniers, and other measuring devices. Typical use cases include in-process quality control on machine shop floors, incoming inspection of parts, and calibration support tasks in metrology labs. The 0.231-inch diameter and 2.0-inch overall length make it well suited for compact bore inspection in both light manufacturing and precision tooling contexts.

Key Features

• Class ZZ Plus tolerance rating of 0.0002 inches for high-accuracy go inspection
• 10 microfinish surface finish reduces wear and ensures consistent gage contact
• Tool steel construction provides durability in production inspection environments
• Meets ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability for calibration records
• Compact 2.0-inch overall length suits confined bore access

Compatibility

Designed as an OEM-style go plug gage for dimensional inspection of machined bores and for setting micrometers, verniers, and other precision measuring devices requiring a 0.231-inch reference standard.

Installation Notes

Plug gages of this type 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 damage to the precision-ground surface. Clean the gage and the bore being checked before use to avoid false readings caused by chips or debris. Follow your facility calibration program and applicable ASME B89.1 guidelines for periodic re-verification of the gage.
