Vermont Gage 111161700 Class Zz Plus Plug Gage 0.617 in

Product Description

The VERMONT GAGE 111161700 is a Class ZZ Plus plug gage designed for precise go inspection of bored holes, machined bores, and other internal features requiring tight dimensional verification. Measuring 0.617 inches in diameter with a tolerance of 0.0002 inches, this plug gage delivers the accuracy required for quality control in precision machining and manufacturing environments. Constructed from tool steel with a 10 microinch surface finish, it provides consistent, repeatable results across repeated use cycles. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Machinists, quality technicians, and metrology professionals are the primary users of this instrument.

This plug gage is suited for go inspection applications in machine shops, toolrooms, and quality assurance departments. It is used to verify that internal diameters fall within specified tolerances when checking machined parts, castings, and fabricated components. The 0.617-inch diameter makes it applicable across a range of bore sizes in both production and inspection settings. It also serves as a reference standard when setting micrometers, verniers, and other measuring devices to a known dimension.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for high-accuracy go inspection
• 10 microinch surface finish for consistent contact and repeatable measurement
• Tool steel construction for durability and wear resistance in production use
• Meets ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability
• Compatible for use when setting micrometers, verniers, and other measuring devices

Compatibility

Suitable for go inspection of 0.617-inch diameter internal features and for setting micrometers, verniers, and other measuring devices requiring a traceable reference standard.

Installation Notes

Plug gages are handled and applied by machinists and quality control technicians following established metrology procedures. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Do not force the gage into a bore; excessive insertion force can damage both the gage and the workpiece. Clean contact surfaces before each use and apply a light protective oil for long-term storage.
