Vermont Gage 111140600 Class Zz Plus Plug Gage 0.406 in

Product Description

The VERMONT GAGE 111140600 is a Class ZZ Plus plug gage designed for go inspection of 0.406-inch diameter bores and holes. Manufactured from tool steel, this fixed-limit gage delivers a tolerance of 0.0002 inches and a 10 microfinish surface, ensuring accurate and repeatable results in production and inspection environments. It comes with a Certificate of Accuracy with NIST traceability, making it suitable for use in quality control programs requiring documented measurement standards. Metrology technicians, machinists, and quality inspectors use this type of gage to verify that a feature meets minimum size requirements before assembly or further machining.

This plug gage is used in machine shops, manufacturing facilities, and metrology labs where go inspection of 0.406-inch features is required. It is also used to calibrate and set micrometers, verniers, and other measuring devices per the application guidance listed under ASME B89.1 standards. Typical applications include incoming inspection, in-process quality checks, and final acceptance inspection of machined bores or drilled holes.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for precise go inspection
• 10 microfinish surface for consistent, low-wear gage contact
• Tool steel construction for durability in production environments
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 dimensional standards
• Suitable for setting micrometers, verniers, and other measuring devices

Compatibility

Designed for go inspection of 0.406-inch diameter bores and holes. Also compatible for use as a setting standard for micrometers, verniers, and other measuring devices as noted in the product application data.

Installation Notes

Plug gages are handled and used by metrology technicians and quality inspectors. Keep the gage surface clean and lightly oiled when not in use to prevent corrosion on the tool steel body. Do not force the gage into a bore; light hand pressure is sufficient for go inspection. Store in its protective case away from heat sources and abrasive materials to maintain calibration integrity.
