Vermont Gage 112112000 Class Zz Plus Plug Gage 12mm

Product Description

The VERMONT GAGE 112112000 is a Class ZZ Plus plug gage designed for go inspection of 12 mm diameter bores, holes, and openings. Manufactured from tool steel with a 10 microfinish surface coating, it delivers a tolerance of 0.00508 mm, making it suitable for precision measurement and quality control work. The gage measures 2.0000 inches in overall length and includes a Certificate of Accuracy with NIST traceability, supporting documentation requirements in regulated manufacturing and inspection environments. Machinists, quality technicians, and tool room professionals use this gage to confirm that a feature accepts the nominal size within specified limits.

This plug gage is used in dimensional inspection applications where go-type verification of 12 mm features is required. It is compatible with standard gage handle systems and is appropriate for use alongside set micrometers, verniers, and other measuring devices requiring a calibration or reference standard. Typical applications include incoming inspection, in-process quality checks, and final part acceptance in machining, manufacturing, and tool room environments. The included NIST-traceable certificate supports ISO and quality management system documentation requirements.

Key Features

• Class ZZ Plus tolerance of 0.00508 mm for precise go inspection
• 12 mm nominal diameter for bore and hole verification
• Tool steel construction for durability and dimensional stability
• 10 microfinish surface coating for smooth, accurate gauging contact
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 standards

Compatibility

Designed for go inspection of 12 mm diameter features and compatible for use with set micrometers, verniers, and other measuring devices as referenced in the product specifications.

Installation Notes

Plug gages are handled and used by quality technicians and machinists in inspection settings. Store the gage in its case and apply a light coat of rust-preventive oil when not in use to protect the tool steel surface. Do not force the gage into a feature; go gages should pass under the weight of the gage alone or with minimal hand pressure. Periodic recalibration against a traceable standard is recommended to maintain accuracy over time.
