Vermont Gage 111162200 Class Zz Plus Plug Gage 0.622in

Product Description

The VERMONT GAGE 111162200 is a Class ZZ Plus plug gage machined from tool steel and designed for precision go inspection of bored holes, reamed openings, and other internal features requiring tight dimensional control. It measures a nominal diameter of 0.622 inches with a tolerance of 0.0002 inches, and carries a 10 microfinish surface finish rating. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for use in documented quality-control processes. Machinists, quality technicians, and metrology professionals use this gage to verify that manufactured features meet specified dimensional limits before parts advance through production.

This plug gage is used in manufacturing, machine shops, and inspection labs wherever a 0.622-inch nominal bore must be verified for conformance. It is equally suited for calibrating and setting micrometers, verniers, and other measuring devices to a known reference diameter. At an overall length of 2.0 inches, it fits comfortably in standard gage handle setups. It is intended for go inspection workflows per ASME B89.1 and is appropriate for both production floor and bench-top inspection environments.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for tight dimensional control
• 10 microfinish surface finish minimizes wear on mating surfaces
• Tool steel construction for hardness and long service life
• Includes Certificate of Accuracy with NIST traceability for documented inspection
• Conforms to ASME B89.1 dimensional gage standards
• Compatible with standard plug gage handles for efficient workflow

Compatibility

Designed for go inspection of 0.622-inch nominal diameter internal features. Also suitable for setting and verifying micrometers, verniers, and other measuring devices requiring a calibrated reference plug.

Installation Notes

Plug gages are handled and used by quality technicians and machinists and require no permanent installation. Keep the gage clean and lightly oiled when not in use to prevent corrosion of the tool steel. Do not force the gage into an undersized bore, as this will cause premature wear or damage to the gage surface. Periodic recalibration against a traceable standard is recommended to maintain measurement integrity.
