Vermont Gage 112108180 Class Zz Plus Plug Gage 8.18mm

Product Description

The VERMONT GAGE 112108180 is a Class ZZ Plus plug gage used to verify bore and hole diameters to a tight tolerance in precision measurement and quality-control applications. Manufactured from tool steel with a 10 microfinish surface coating, this gage checks an 8.18 mm diameter with a tolerance of 0.005 mm (0.00508 mm actual). It ships with a Certificate of Accuracy traceable to NIST, confirming it meets ASME B89.1 standards. Licensed metrologists, machinists, and quality technicians use this gage to confirm dimensional conformance on machined parts.

This plug gage is suited for go inspection tasks in manufacturing, tool and die, and precision machining environments. It works alongside micrometers, verniers, and other measuring devices to validate bore geometry during production runs or incoming inspection. With an overall length of 2.0 inches, it fits comfortably in hand for bench-inspection work. Both production floor and metrology lab environments are typical deployment settings for this gage class.

Key Features

• Class ZZ Plus tolerance grade at 0.005 mm for precise go inspection
• Tool steel construction provides hardness and wear resistance
• 10 microfinish surface coating ensures accurate contact measurement
• Includes Certificate of Accuracy with NIST traceability
• Meets ASME B89.1 standard for dimensional gaging
• Compact 2.0-inch overall length suits bench and in-process inspection

Compatibility

Designed for use in go inspection applications and compatible with standard gage handle setups. Intended for use alongside set micrometers, verniers, and other measuring devices where ASME B89.1-compliant bore verification is required.

Installation Notes

Plug gages are handled and used by qualified machinists, metrologists, or quality technicians. Store the gage in its protective case when not in use to prevent damage to the finished surface. Clean the gage and the bore to be measured before use to avoid false readings from debris or oil buildup. Never force the gage into a bore; apply only light, consistent hand pressure to protect both the gage and the workpiece.
