Vermont Gage 112105640 Class Zz Plus Plug Gage 5.64mm

Product Description

The VERMONT GAGE 112105640 is a Class ZZ Plus cylindrical plug gage used to verify bore diameters to a high degree of dimensional accuracy. Manufactured from tool steel with a 10 microfinish surface coating, this gage checks a 5.64 mm diameter bore and carries a tolerance of 0.00508 mm. It conforms to ASME B89.1 standards and ships with a Certificate of Accuracy with NIST traceability. Licensed metrologists, quality control technicians, and precision machining shops rely on this type of instrument to confirm whether a machined hole falls within acceptable Go tolerance limits before assembly or final inspection.

This plug gage is used in precision inspection environments where bore diameter verification is required. Typical applications include Go inspection of drilled, reamed, or bored holes, as well as setting and verifying micrometers, verniers, and other measuring devices. It is suited for use in manufacturing, toolroom, and quality lab settings handling parts at the 5.64 mm nominal bore size. The overall length of 2.0000 inches accommodates standard handle holders common in inspection setups.

Key Features

• Class ZZ Plus tolerance grade with 0.00508 mm tolerance for precise Go inspection
• 5.64 mm nominal diameter for direct bore verification at that dimension
• 10 microfinish surface coating for smooth, repeatable gage entry
• Tool steel construction for durability and dimensional stability
• Meets ASME B89.1 dimensional standards
• Includes Certificate of Accuracy with NIST traceability for calibration documentation

Compatibility

Designed as a Go inspection plug gage for verifying 5.64 mm diameter bores; also suitable for setting micrometers, verniers, and other measuring devices as specified by the manufacturer.

Installation Notes

This gage is handled and used by quality technicians and metrologists in inspection environments, not installed in a mechanical system. Before use, clean the gage and bore thoroughly to remove debris, oil, or burrs that could affect measurement accuracy or damage the gage surface. Never force the gage into a bore; if resistance is felt, re-inspect the workpiece. Store the gage in its protective case when not in use to prevent corrosion and surface damage.
