Vermont Gage 111126100 Class Zz Plus Plug Gage 0.261 in

Product Description

The VERMONT GAGE 111126100 is a Class ZZ Plus plug gage machined from tool steel for precise dimensional inspection of hole and bore diameters. It measures a nominal diameter of 0.261 inches with a tolerance of 0.0002 inches and features a 10 microfinish surface for consistent, repeatable contact. Each unit ships with a Certificate of Accuracy backed by NIST traceability, confirming the gage meets ASME B89.1 standards. Machinists, quality control technicians, and metrology professionals use this plug gage to verify critical bore dimensions during production and inspection workflows.

This plug gage is suited for go inspection applications where hole diameter acceptance must be confirmed against a tight tolerance. Typical use cases include verifying drilled, reamed, or bored holes in production machining environments, as well as setting and checking micrometers, verniers, and other measuring devices. The 2.0-inch overall length provides comfortable handling during bench or in-process inspection. It is appropriate for both job-shop and high-volume manufacturing quality assurance programs.

Key Features

• Class ZZ Plus tolerance grade: 0.0002 inches for tight dimensional control
• 10 microfinish surface for accurate, repeatable gage contact
• Tool steel construction for durability in production inspection environments
• NIST-traceable Certificate of Accuracy included with each unit
• Complies with ASME B89.1 dimensional gage standards
• Compact 2.0-inch overall length for easy single-hand use

Compatibility

Designed for go inspection of 0.261-inch nominal diameter bores and holes. Also suitable for setting and verifying micrometers, verniers, and other precision measuring devices requiring a Class ZZ Plus reference standard.

Installation Notes

Plug gages are handled and used by metrology and quality control personnel; no permanent installation is required. Store the gage in its protective case when not in use to prevent surface damage and contamination. Clean the gage surface and the bore being inspected before use to avoid false readings caused by debris or cutting fluid. Do not force the gage into an undersized bore, as this can damage the gage surface and compromise calibration.
