Vermont Gage 111103100 Class Zz Plus Plug Gage 0.031 in

Product Description

The VERMONT GAGE 111103100 is a Class ZZ Plus plug gage machined from tool steel for precision dimensional inspection. It measures a nominal diameter of 0.031 inches with a tolerance of 0.0002 inches and features a 10 microfinish surface. Manufactured to ASME B89.1 standards, it includes a Certificate of Accuracy with NIST traceability. The overall length is 2 inches. This gage is used by metrology technicians and quality control personnel to verify bore and hole dimensions in production and inspection environments.

Class ZZ Plus plug gages at this diameter range are suited for go inspection of small-diameter holes, bores, and precision-machined features. They are commonly used alongside set micrometers, verniers, and other calibrated measuring devices to confirm conformance to tight dimensional tolerances. This gage is appropriate for both shop-floor inspection and metrology lab use where NIST-traceable documentation is required for quality records.

Key Features

• Nominal measurement diameter of 0.031 inches with 0.0002 inches tolerance
• Class ZZ Plus accuracy grade per ASME B89.1
• 10 microfinish surface for consistent, repeatable contact
• Tool steel construction for wear resistance and dimensional stability
• Includes Certificate of Accuracy with NIST traceability
• Overall length of 2 inches for easy handling in tight inspection areas

Compatibility

Designed for go inspection applications and compatible for use with set micrometers, verniers, and other calibrated measuring devices requiring a NIST-traceable reference standard at 0.031 inches diameter.

Installation Notes

Plug gages are handled and used by quality control technicians and metrologists. Clean the gage and the workpiece bore before use to remove debris, cutting fluid, or contaminants that could affect measurement accuracy. Do not force the gage into a bore; apply light, consistent hand pressure only. Store the gage in its protective case when not in use to prevent corrosion, surface damage, or dimensional drift.
