Vermont Gage 112105600 Class Zz Plus Plug Gage 5.6mm

Product Description

The VERMONT GAGE 112105600 is a Class ZZ Plus cylindrical plug gage designed for go inspection of bored, drilled, and reamed holes with a nominal diameter of 5.6 mm. Manufactured from tool steel, it delivers a 10 microfinish surface and holds a tolerance of 0.00508 mm, making it well suited for precision measurement work in quality control and machining environments. The gage ships with a Certificate of Accuracy traceable to NIST, satisfying documentation requirements in ISO and AS9100-registered facilities. Machinists, quality technicians, and metrology lab personnel are the primary users of this tool.

This plug gage is used in production and inspection settings wherever hole diameter verification is required at the 5.6 mm nominal size. Typical applications include setting and verifying micrometers, verniers, and other measuring devices, as well as direct go inspection of workpiece features. The 2.0-inch overall length fits standard gage handle systems, making it practical for benchtop and floor-level inspection stations in both job shop and high-volume manufacturing environments.

Key Features

• Class ZZ Plus tolerance of 0.00508 mm for high-accuracy go inspection
• 10 microfinish surface for consistent, repeatable gage contact
• Tool steel construction for wear resistance and dimensional stability
• Includes Certificate of Accuracy with NIST traceability
• Meets ASME B89.1 standard for plain plug gages
• 2.0-inch overall length compatible with standard gage handle systems

Compatibility

Designed for use with standard plug gage handles accepting 5.6 mm diameter gage members, and suitable for setting micrometers, verniers, and other measuring devices per the manufacturer application listing.

Installation Notes

Plug gages should be handled with clean, dry gloves or gage handling tools to prevent corrosion from skin contact. Before use, verify the gage member is free of nicks, burrs, or contamination that could affect measurement accuracy. Store the gage in its protective case when not in use, and recalibrate on a schedule consistent with ASME B89.1 and your facility quality plan. No power tools or torque application are involved in normal plug gage use.
