Vermont Gage 112112040 Class Zz Plus Plug Gage 12.04 Mm

Product Description

The VERMONT GAGE 112112040 is a Class ZZ Plus plug gage designed for go inspection of machined bores and holes with a nominal diameter of 12.04 mm. Manufactured from tool steel and finished to a 10 microfinish surface, this gage provides reliable dimensional verification in shop-floor and quality-control environments. It carries NIST-traceable certification and is built to ASME B89.1 standards, making it a dependable reference tool for inspectors and machinists verifying bore tolerances to within 0.00508 mm. The overall length is 2.0000 inches, and the unit weighs approximately 0.1 pounds.

This plug gage is suited for use in manufacturing inspection stations, machine shops, and quality labs where bore diameter conformance must be confirmed before parts advance to assembly. It is compatible with go inspection procedures and can be used alongside set micrometers, verniers, and other precision measuring devices to cross-reference bore dimensions. Typical users include QC inspectors, machinists, and metrology technicians working in both low-volume job shops and high-throughput production environments where ASME B89.1 compliance is required.

Key Features

• Class ZZ Plus tolerance rating with 0.00508 mm tolerance for precise go inspection
• Tool steel construction for durability and dimensional stability under repeated use
• 10 microfinish surface coating for smooth, consistent gage contact
• Includes Certificate of Accuracy with NIST traceability for quality documentation
• Meets ASME B89.1 dimensional gage standards
• Compact 2.0000-inch overall length for easy handling and storage

Compatibility

Designed for go inspection of 12.04 mm diameter bores. Suitable for use with set micrometers, verniers, and other calibrated measuring devices in standard inspection workflows.

Installation Notes

This gage is handled and used by QC inspectors and metrology technicians rather than installed in a system. Before use, clean the gage and the bore being measured to remove chips, coolant, and debris that could affect the reading. Store the gage in its protective case when not in use to prevent surface damage. Follow your facility calibration schedule and handle with clean cotton gloves to prevent corrosion from skin contact.
