Vermont Gage 111343550 Class Zz Plus Plug Gage

Product Description

The VERMONT GAGE 111343550 is a Class ZZ Plus cylindrical plug gage used to verify bore diameters in precision machining and quality control applications. It measures 0.4355 inches in diameter with a tolerance of 0.0002 inches, making it suitable for go inspection work where tight dimensional control is required. The gage is manufactured from tool steel and features a 10 microfinish surface. Each unit ships with a Certificate of Accuracy with NIST Traceability, confirming it meets ASME B89.1 standards. Machinists, quality technicians, and metrology professionals use this gage as a reliable go-no-go reference tool.

This plug gage is used in machine shops, manufacturing facilities, and inspection departments for verifying internal bore dimensions on machined parts. The 0.4355-inch diameter makes it appropriate for checking holes where tight fit tolerances are critical. It is also suited for setting and verifying micrometers, verniers, and other measuring devices. The overall length of 2.0 inches provides a manageable grip for bench and floor-level inspection work. Class ZZ Plus designation indicates it falls within the highest accuracy class for plain plug gages in this size range.

Key Features

• 10 microfinish surface for accurate, repeatable contact with bore surfaces
• Meets ASME B89.1 standards for plain plug gage accuracy
• Includes Certificate of Accuracy with NIST Traceability for documentation and calibration records
• Compact 2.0-inch overall length suits bench-top and in-process inspection

Compatibility

Designed for use in go inspection applications and for setting micrometers, verniers, and other precision measuring devices requiring a 0.4355-inch reference diameter.

Installation Notes

Plug gages are used by quality technicians and machinists and require no installation in the traditional sense. Clean the gage and the bore being inspected before use to prevent contamination from affecting measurements. Handle with care to avoid dropping or contact with abrasive surfaces, as damage to the gage surface can compromise accuracy. Store in a protective case when not in use and recalibrate periodically per your quality management system requirements.
