Vermont Gage 912302650 Class Zz Plus Plug Gage 2.65 Mm

Product Description

The VERMONT GAGE 912302650 is a Class ZZ Plus plug gage designed for precision dimensional inspection of bored holes and machined features. It measures 2.65 mm in diameter and carries a tolerance of 0.00508 mm, making it suitable for Go inspection applications where tight process control is required. The gage is machined from tool steel and finished with a black oxide coating for corrosion resistance and reduced light glare during use. A Certificate of Accuracy with NIST traceability is included, supporting documentation requirements in quality management systems. Metrology technicians, machinists, and quality control inspectors use this type of gage as part of routine attribute gauging programs.

This plug gage is used in manufacturing and inspection environments where hole diameter verification is performed to ASME B89.1 standards. It is well suited for use alongside set micrometers, verniers, and other precision measuring devices in tool rooms, inspection labs, and production floor QC stations. The compact form factor and standard handle design allow it to fit into existing gage pin sets or be used as a standalone Go gage for process verification on small-diameter bores.

Key Features

• 2.65 mm diameter with 0.00508 mm tolerance for precise Go inspection
• Class ZZ Plus classification per ASME B89.1 standard
• Tool steel construction with black oxide finish for durability and corrosion resistance
• Includes Certificate of Accuracy with NIST traceability
• Compatible with set micrometers, verniers, and other calibrated measuring devices
• Overall length of 2.0000 inches for standard handle fitment

Compatibility

Designed for Go inspection use with set micrometers, verniers, and other precision measuring devices per ASME B89.1 requirements. Suitable as a replacement or supplemental gage pin in standard plug gage handle systems accepting 2.65 mm diameter members.

Installation Notes

Plug gages are handled and used by trained metrology technicians or quality control inspectors. Store the gage in its protective case and handle with clean cotton gloves to prevent corrosion from skin oils. Before use, inspect the gage surface for nicks or burrs and clean with an approved instrument cleaner. Do not force the gage into a bore; excessive insertion force can damage both the gage and the workpiece.
