Vermont Gage 112111300 Class Zz Plus Plug Gage 11.3mm

Product Description

The VERMONT GAGE 112111300 is a Class ZZ Plus plug gage designed for precision bore inspection in metalworking and quality control environments. It measures 11.3 mm in diameter with a tolerance of 0.005 mm, making it suitable for verifying hole sizes to tight dimensional standards. The gage features a 10 microfinish surface coating that reduces wear and maintains accuracy over repeated use. Overall length is 2.0 inches. Constructed from tool steel for durability, this gage is intended for use by machinists, quality technicians, and metrology professionals performing go inspection work.

This plug gage is used in go inspection applications to verify that a bored or drilled hole meets minimum size requirements. It is appropriate for use in machine shops, manufacturing facilities, and quality labs where hole tolerances must be confirmed before assembly. The gage is also suitable for setting and verifying micrometers, verniers, and other measuring devices. Each unit ships with a Certificate of Accuracy that includes NIST traceability, supporting documented inspection processes and audit requirements.

Key Features

• Class ZZ Plus tolerance class with 0.005 mm tolerance for precise go inspection
• 11.3 mm diameter for direct bore verification
• 10 microfinish surface coating reduces wear and maintains dimensional accuracy
• Tool steel construction for long service life in production environments
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 standards

Compatibility

Designed for go inspection of 11.3 mm bored or drilled holes and for setting micrometers, verniers, and other measuring devices where an 11.3 mm reference standard is required.

Installation Notes

Plug gages should be handled by qualified metrology or quality control personnel. Clean the gage and the workpiece bore before use to prevent false readings caused by debris or coolant. Never force the gage into an undersized bore, as this can damage the gage surface and compromise its accuracy. Store the gage in its case when not in use to protect the finished surface and maintain calibration integrity.
