Vermont Gage 111170800 Class Zz Plus Plug Gage 0.708 in

Product Description

The VERMONT GAGE 111170800 is a Class ZZ Plus plug gage machined from tool steel for dimensional inspection of bored holes, machined features, and precision-fit components. It measures a nominal diameter of 0.708 inches with a tolerance of 0.0002 inches and a surface finish of 10 microinch, delivering repeatable go-inspection accuracy in a workshop or production environment. Each unit ships with a Certificate of Accuracy traceable to NIST, satisfying documentation requirements for quality control programs and ISO-compliant inspection records. Machinists, quality technicians, and tool-and-die professionals reach for this type of gage when a direct, attribute-style pass-fail check is faster and more reliable than a variable measurement instrument.

This plug gage is suited for go inspection on production lines, incoming material inspection, and calibration verification of set micrometers, verniers, and other measuring devices. It conforms to ASME B89.1 standards, making it appropriate for use in both commercial machine shops and regulated manufacturing environments. The overall length of 2.0 inches provides enough handle for secure single-hand operation during repetitive inspection cycles without operator fatigue.

Key Features

• Class ZZ Plus tolerance rating of 0.0002 inches for high-accuracy go inspection
• Tool steel construction for hardness and dimensional stability over service life
• 10 microinch surface finish reduces bore wear during repeated insertions
• Includes Certificate of Accuracy with NIST traceability for QC documentation
• Conforms to ASME B89.1 dimensional gage standards
• Overall length of 2.0 inches supports controlled, single-hand operation

Compatibility

Designed for go inspection of features at a nominal diameter of 0.708 inches; also used to set and verify micrometers, verniers, and other precision measuring devices requiring a traceable reference standard at this diameter.

Installation Notes

Plug gages are handled and stored by metrology or quality technicians, not installed in systems. Clean the gage and the workpiece bore with a lint-free cloth before use to prevent debris from affecting the measurement or damaging the finish. Store the gage in its protective case away from ferrous chips and cutting fluids when not in use. Do not force the gage into an undersized bore; if resistance is felt, remove and re-measure the feature before proceeding.
