Vermont Gage 111163400 Class Zz Plus Plug Gage 0.634 in

Product Description

The VERMONT GAGE 111163400 is a Class ZZ Plus plug gage designed to verify bore and hole diameters with precision tool-steel construction. It measures 0.634 inches in diameter with a tolerance of 0.0002 inches and a 10 microfinish surface, making it suitable for demanding Go inspection work. The gage is 2.0 inches in overall length and ships with a Certificate of Accuracy that includes NIST traceability, meeting ASME B89.1 standards. Machinists, quality technicians, and metrology professionals use this type of plug gage as a reliable attribute-inspection tool in production and inspection environments.

This plug gage is used for Go inspection of machined holes, bores, and other cylindrical features requiring tight dimensional control. It is also suited for setting and verifying micrometers, verniers, and other measuring devices that require a certified reference. Typical applications include incoming inspection, in-process quality checks, and final part acceptance in machine shops, manufacturing facilities, and toolrooms. The 0.634-inch diameter and Class ZZ Plus tolerance class make it appropriate for moderate-precision inspection work where ASME B89.1 compliance is required.

Key Features

• Class ZZ Plus tolerance class with 0.0002-inch tolerance for consistent Go inspection results
• 10 microfinish surface for accurate, low-wear contact with measured bores
• Tool steel construction for durability in production inspection environments
• Includes Certificate of Accuracy with NIST traceability
• Meets ASME B89.1 dimensional standards
• Compatible with use as a setting reference for micrometers, verniers, and other measuring devices

Compatibility

Designed for Go inspection of holes and bores at 0.634 inches nominal diameter. Also suitable for setting micrometers, verniers, and other measuring devices requiring a certified plug reference, as stated by the manufacturer.

Installation Notes

Plug gages of this type are handled by quality technicians and metrology personnel and do not require mechanical installation. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Clean contact surfaces before each use and avoid dropping or mishandling, as impact can alter dimensional accuracy. Periodic recalibration against a traceable standard is recommended to maintain inspection integrity.
