Vermont Gage 111119000 Class Zz Plus Plug Gage 0.19 in

Product Description

The VERMONT GAGE 111119000 is a Class ZZ Plus plug gage designed for precise go inspection of hole diameters and bore tolerances. Measuring 0.19 inches in diameter, it holds a tolerance of 0.0002 inches and features a 10 microfinish surface for consistent, reliable contact. Machined from tool steel, this gage delivers the dimensional stability required for repetitive inspection work. Each unit ships with a Certificate of Accuracy with NIST traceability, making it suitable for use in calibrated measurement environments. Metrology technicians, machinists, and quality control personnel rely on this type of gage for fast, definitive go or no-go decisions on production parts.

This plug gage is used in go inspection applications where hole diameter must be verified against a specified tolerance. It is compatible with standard gage handle holders and is appropriate for use alongside set micrometers, verniers, and other precision measuring devices. Typical applications include incoming inspection, in-process quality checks, and final verification of machined bores in manufacturing and machine shop environments. The 2.0-inch overall length provides comfortable handling in bench and floor-level inspection setups. Conforms to ASME B89.1 dimensional standards for plain cylindrical plug gages.

Compatibility

Designed for use with standard plug gage handle holders in go inspection setups. Suitable for use alongside set micrometers, verniers, and other precision measuring devices as stated by the manufacturer.

Installation Notes

Plug gages are installed and used by metrology technicians, machinists, and quality control inspectors. Before use, ensure the gage and workpiece bore are clean and free of burrs, chips, or contaminants that could affect measurement accuracy or damage the gage surface. Store the gage in its protective case when not in use to prevent nicks or corrosion on the precision-ground surface. Handle with clean, dry gloves or a lint-free cloth to avoid transferring oils and moisture that can affect microfinish integrity.
