Vermont Gage 111199500 Class Zz Plus Plug Gage 0.995 in

Product Description

The VERMONT GAGE 111199500 is a Class ZZ Plus plug gage ground from tool steel to a 0.995-inch nominal diameter with a bilateral tolerance of 0.0002 inches and a 10 microinch surface finish. It is used for go inspection of machined bores, holes, and internal features to verify dimensional conformance. The 111199500 ships with a Certificate of Accuracy bearing NIST traceability and is manufactured to ASME B89.1 standards. Machinists, quality technicians, and tool-room personnel use this gage as a working inspection tool and as a reference for setting micrometers, verniers, and other measuring devices.

This plug gage is suited for use in production inspection, incoming inspection, and tool-room calibration environments. Its 2.0-inch overall length provides a secure, ergonomic grip during single-handed bore checks. The 10 microinch finish minimizes gage wear during repeated insertion cycles, making it appropriate for moderate-volume inspection on machine shop floors and quality labs handling close-tolerance work.

Key Features

• 0.995-inch nominal diameter ground to Class ZZ Plus tolerance of 0.0002 inches
• 10 microinch surface finish for reduced gage wear and consistent contact
• Tool steel construction for hardness and dimensional stability
• Manufactured to ASME B89.1 dimensional standard
• Includes Certificate of Accuracy with NIST traceability
• Suitable for setting micrometers, verniers, and other measuring devices

Compatibility

Designed for go inspection of bores and internal features at 0.995-inch nominal diameter. Also used as a setting standard for micrometers, verniers, and other measuring devices per the application data provided by the manufacturer.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no power tools or utilities need to be isolated for normal inspection use. Store the gage in its protective case when not in use and keep it clean and lightly oiled to prevent corrosion. Do not force the gage into a bore; excessive insertion force can damage both the gage and the workpiece. Calibration intervals should follow your facility quality system and applicable ASME or ISO measurement standards.
