Vermont Gage 111304150 Class Zz Plus Plug Gage 0.0415 in

Product Description

The VERMONT GAGE 111304150 is a Class ZZ Plus plug gage designed to perform go inspection on drilled, reamed, and bored holes with a nominal diameter of 0.0415 inches. Manufactured from tool steel and finished to a 10 microfinish surface, this plug gage delivers tight dimensional control with a tolerance of 0.0002 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming conformance to ASME B89.1 standards. It is intended for use by quality technicians, machinists, and inspection professionals who require reliable, repeatable hole-size verification in a production or inspection environment.

This plug gage is suited for go-side inspection tasks in machine shops, manufacturing facilities, and metrology labs. At 0.0415 inches in diameter and 2.0 inches in overall length, it is sized for small-bore applications. In addition to direct hole gauging, the part is applicable for setting micrometers, verniers, and other precision measuring devices that require a traceable reference standard. It fits workflows where consistent part acceptance criteria must be enforced across high-volume or precision-tolerance production runs.

Key Features

• Class ZZ Plus tolerance grade with 0.0002 inch tolerance for precise go inspection
• 10 microfinish surface finish reduces wear and maintains dimensional integrity over repeated use
• Tool steel construction provides hardness and durability appropriate for production gauging
• Includes Certificate of Accuracy with NIST traceability, meeting ASME B89.1 standards
• Applicable for setting micrometers, verniers, and other precision measuring instruments
• Compact 2.0 inch overall length suited for small-bore and confined-space inspection

Compatibility

Designed for go inspection of holes at 0.0415 inches nominal diameter and for use as a reference standard when setting micrometers, verniers, and other measuring devices requiring a traceable gauge.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no power source or utilities need to be shut down prior to use. Handle with clean, lint-free gloves or a clean cloth to prevent oils and debris from affecting the gauge surface or measurement accuracy. Store in the provided case or a protected location to avoid nicks, burrs, or corrosion that could affect the gauge diameter. Periodic cleaning and recertification intervals should follow the facility quality management plan and applicable ASME B89.1 guidelines.
