Vermont Gage 112316090 Class Zz Plus Plug Gage 16.09mm

Product Description

The VERMONT GAGE 112316090 is a Class ZZ Plus plug gage designed for precision bore inspection and dimensional verification in industrial and metrology applications. It measures 16.09 mm in diameter with a tolerance of 0.00508 mm and features a 10 microinch surface finish. Manufactured from tool steel, this gage provides the rigidity and wear resistance required for repeatable go-inspection work. Each unit ships with a Certificate of Accuracy that includes NIST traceability, meeting the documentation requirements for calibrated inspection environments. Manufactured to ASME B89.1 standards, it integrates into any controlled measurement program without additional qualification steps.

This plug gage is suited for go inspection of bored, drilled, or reamed holes where close-tolerance dimensional control is required. It is also used as a setting standard for micrometers, verniers, and other precision measuring devices. Typical users include machinists, quality technicians, and metrology lab personnel working in precision manufacturing, tooling, and inspection environments. The overall length is 2.0000 inches, making it compatible with standard gage-handle systems used in production and bench inspection setups.

Key Features

• Class ZZ Plus tolerance grade with 0.00508 mm tolerance for high-accuracy go inspection
• 16.09 mm diameter ground to a 10 microinch surface finish
• Tool steel construction for hardness and dimensional stability under repeated use
• Meets ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability for calibrated inspection records
• 2.0000-inch overall length compatible with standard plug gage handles

Compatibility

Designed for use in go inspection applications and as a setting reference for micrometers, verniers, and other precision measuring devices. Compatible with standard plug gage handle systems that accept the 2.0000-inch overall length form factor.

Installation Notes

Plug gages are installed and used by quality technicians and machinists in inspection environments. Before use, clean the gage and bore contact surfaces to remove debris, oil, or particulate that could affect measurement accuracy. Do not force the gage into a bore; apply only light hand pressure consistent with go-gage practice. Store in a protective case away from temperature extremes to maintain dimensional stability and protect the calibrated surface finish.
