Vermont Gage 111309350 Class Zz Plus Plug Gage 0.0935 in

Product Description

The VERMONT GAGE 111309350 is a Class ZZ Plus plug gage designed for precision dimensional inspection of small-diameter bores and holes. Measuring 0.0935 inches in diameter with a tolerance of 0.0002 inches, this gage delivers the accuracy required for go-inspection applications in machine shops, quality control labs, and production environments. The overall length is 2.0 inches, making it easy to handle and position. Manufactured from tool steel with a 10 microfinish surface, it is built to withstand repeated use while maintaining dimensional integrity. A Certificate of Accuracy with NIST traceability is included, supporting documented quality processes and audit requirements.

This plug gage is suited for go inspection of precision bores where tight tolerances must be verified before components move to the next stage of production. It is also used to set and calibrate instruments such as micrometers, verniers, and other measuring devices that require a traceable reference standard. Typical users include machinists, quality technicians, toolmakers, and metrology professionals working in both job-shop and high-volume manufacturing settings. The small diameter makes it especially relevant for applications involving fine-pitch fastener clearances, instrument ports, and other close-tolerance small-bore work.

Key Features

• Class ZZ Plus tolerance specification: 0.0002 inches for high-accuracy go inspection
• Tool steel construction for durability and dimensional stability under repeated use
• 10 microfinish surface for consistent, reliable contact during inspection
• Includes Certificate of Accuracy with NIST traceability for documented quality compliance
• Conforms to ASME B89.1 standards
• Compact 2.0-inch overall length for easy handling in confined inspection setups

Compatibility

Designed for go inspection of 0.0935-inch diameter bores and as a reference standard for setting micrometers, verniers, and other precision measuring devices. Suitable for use wherever ASME B89.1 Class ZZ Plus plug gage specifications are required.

Installation Notes

Plug gages should be handled and stored carefully to prevent damage to the precision-ground surface. Always clean the gage and the bore being inspected before use to avoid false readings caused by debris or contaminants. Do not force the gage into a bore; apply only light, consistent hand pressure during inspection. Periodic re-verification against the included NIST-traceable certificate is recommended as part of a calibration control program.
