Vermont Gage 111146100 Class Zz Plus Plug Gage 0.461 in

Product Description

The VERMONT GAGE 111146100 is a Class ZZ Plus plug gage designed for precise go inspection of bored holes, drilled passages, and machined features. The gage measures a nominal diameter of 0.461 inches with a tolerance of 0.0002 inches, making it suitable for dimensional verification in tight-tolerance manufacturing environments. Constructed from tool steel and finished to a 10 microfinish surface, it delivers consistent contact performance over repeated use. A Certificate of Accuracy with NIST Traceability is included, meeting the documentation requirements common in ISO- and AS9100-registered shops. Machinists, quality technicians, and tool-room personnel are the primary users of this type of gage.

This plug gage is used in machine shops, manufacturing facilities, and inspection departments where go-type attribute gauging is required. It is well suited for verifying hole diameters on turned, milled, or drilled workpieces prior to assembly. The 0.461-inch diameter makes it a direct-fit solution for inspecting that specific nominal bore size. It is also referenced when setting and verifying micrometers, verniers, and other measuring devices, providing a traceable physical standard for instrument calibration checks. Typical applications include production-floor spot checks and incoming or final inspection stages.

Key Features

• 0.461-inch nominal diameter with 0.0002-inch tolerance for precise go-type attribute inspection
• Tool steel construction for durability and wear resistance in production environments
• 10 microfinish surface finish for consistent, repeatable contact with the workpiece bore
• Includes Certificate of Accuracy with NIST Traceability to support quality system documentation
• Conforms to ASME B89.1 standards for plain plug gages
• Suitable for use as a reference standard when setting micrometers, verniers, and similar measuring instruments

Compatibility

Designed for go inspection of 0.461-inch nominal diameter bored or drilled features. Also compatible as a reference artifact for setting and verifying micrometers, verniers, and other measuring devices where a traceable physical standard is required.

Installation Notes

Plug gages are handled and used by quality technicians and machinists and do not require mechanical installation. Store the gage in its protective case when not in use and avoid dropping or contacting hard surfaces that could damage the precision-ground surface. Clean the gage and the part bore before inspection to prevent debris from causing false readings. Handle with clean cotton gloves or wipers to prevent corrosion from skin contact, and follow your facility calibration control procedures for periodic re-certification.
