Vermont Gage 111110900 Class Zz Plus Plug Gage 0.109 in

Product Description

The VERMONT GAGE 111110900 is a Class ZZ Plus plug gage designed for precise go inspection of 0.109-inch diameter bores and holes. Machined from tool steel and finished to a 10 microfinish surface, this gage delivers a 0.0002-inch tolerance to confirm that a measured feature meets minimum acceptable size. Plug gages of this class are standard tools in dimensional inspection workflows, used to verify that a bore is large enough to accept a mating part. Each unit ships with a Certificate of Accuracy with NIST Traceability, confirming conformance to ASME B89.1 standards.

This gage is suited for use in machine shops, manufacturing facilities, and quality-control environments where consistent, repeatable go inspection is required. It is also appropriate for setting and verifying micrometers, verniers, and other precision measuring devices. The 0.109-inch nominal diameter and 2.0-inch overall length make it well suited for small-bore inspection tasks in production or toolroom settings. Installation and use require no special tooling beyond standard gage handling practices.

Key Features

• Class ZZ Plus tolerance grade with 0.0002-inch tolerance for reliable go inspection
• Tool steel construction for durability and dimensional stability
• 10 microfinish surface for accurate, low-wear contact
• Includes Certificate of Accuracy with NIST Traceability
• Conforms to ASME B89.1 dimensional standards
• Suitable for setting micrometers, verniers, and other measuring devices

Compatibility

Designed for go inspection of 0.109-inch diameter features and for use as a reference standard when setting micrometers, verniers, and comparable precision measuring instruments.

Installation Notes

Handle plug gages with clean, dry hands or lint-free gloves to prevent corrosion and dimensional error from skin oils. Before use, inspect the gage surface for nicks, burrs, or wear that could affect measurement accuracy. Store the gage in its protective case when not in use and allow it to thermally stabilize to room temperature before taking measurements. Periodic recalibration against a traceable standard is recommended to maintain measurement integrity.
