Vermont Gage 111162900 Class Zz Plus Plug Gage 0.629 in

Product Description

The VERMONT GAGE 111162900 is a Class ZZ Plus plug gage designed for go inspection applications in precision measurement environments. Built from tool steel with a 10 microinch surface finish, this gage delivers a measurement diameter of 0.629 inches and holds a tolerance of 0.0002 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming conformance to ASME B89.1 standards. Machinists, quality technicians, and metrology professionals rely on Class ZZ Plus plug gages to verify bore and hole dimensions during incoming inspection, in-process checks, and final part acceptance.

This plug gage is suited for use in production and inspection environments where go-type dimensional verification is required. It is compatible with standard gage handle systems and works alongside set micrometers, verniers, and other precision measuring devices for calibration and reference purposes. The 2.0-inch overall length provides a practical handling profile for benchtop and floor-level inspection tasks. Typical users include quality control technicians, tool room machinists, and calibration lab personnel working to tight dimensional tolerances.

Key Features

• Class ZZ Plus tolerance grade: 0.0002 inches for high-accuracy go inspection
• 10 microinch surface finish for consistent, repeatable gage contact
• Tool steel construction for wear resistance and long service life
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 dimensional standards
• 2.0-inch overall length for easy handling in standard gage setups

Compatibility

Designed for go inspection use with set micrometers, verniers, and other precision measuring devices as stated by the manufacturer. Fits standard plug gage handle systems appropriate for the 0.629-inch diameter range.

Installation Notes

Plug gages are handled and used by quality technicians and tool room machinists — no power tools or utility shutoffs are required. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Do not force the gage into a bore; excessive insertion force will wear the gage and produce false readings. Store in a protective case away from temperature extremes to maintain dimensional stability and preserve NIST-traceable accuracy.
