Vermont Gage 111163300 Class Zz Plus Plug Gage 0.633 in

Product Description

The VERMONT GAGE 111163300 is a Class ZZ Plus plug gage designed for precision dimensional inspection of bored holes, machined bores, and similar internal features. Built from tool steel with a 10 microinch surface finish, it measures a nominal diameter of 0.633 inches with a tolerance of 0.0002 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming the gage meets ASME B89.1 standards. Machinists, quality technicians, and tool room personnel use this plug gage as part of a go inspection routine to verify that a bore falls within acceptable dimensional limits.

This plug gage is suited for go inspection applications in production and quality control environments. It is commonly used alongside set micrometers, verniers, and other precision measuring devices to verify bore dimensions on machined components. The overall length of 2.0 inches makes it compatible with standard gage handle configurations used on the shop floor. It is appropriate for both job shop and high-volume manufacturing settings where consistent bore verification is required.

Key Features

• 10 microinch surface finish for consistent, repeatable contact with the bore surface
• Complies with ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability for documentation and calibration records
• Overall length of 2.0 inches fits standard gage handle assemblies

Compatibility

Designed for use with standard plug gage handle assemblies and compatible with go inspection setups alongside set micrometers, verniers, and other precision measuring devices as noted in the product specifications.

Installation Notes

Plug gages are handled and used by quality technicians and machinists in inspection environments. Keep the gage surface clean and lightly oiled when not in use to prevent corrosion on the tool steel. Never force the gage into a bore; apply light, consistent hand pressure only. Store in a protective case away from temperature extremes to maintain dimensional stability and calibration integrity.
