Vermont Gage 112111340 Class Zz Plus Plug Gage 11.34mm

Product Description

The VERMONT GAGE 112111340 is a Class ZZ Plus plug gage manufactured from tool steel for dimensional inspection of bored and reamed holes. The gage measures 11.34 mm in diameter with a tolerance of 0.00508 mm, making it suitable for high-repeatability go inspection work in tool rooms, machine shops, and quality-control environments. The 10 microfinish surface finish reduces wear on the gage member and the workpiece bore during repeated insertion. At 2.0000 inches overall length, the handle is sized for standard single-end plug gage handles used by machinists, metrologists, and QC inspectors. Each unit ships with a Certificate of Accuracy traceable to NIST standards, meeting the documentation requirements common in ISO-registered facilities.

This plug gage is used to verify that a machined bore falls within its acceptable lower-limit dimension during go inspection. It is appropriate for use in production-line inspection, incoming inspection, and tool calibration setups involving set micrometers, verniers, and other comparative measuring devices. The Class ZZ Plus tolerance class suits general inspection work where close process control is required but Class Z or tighter tolerances are not mandated. Installation in a standard plug gage handle is typical; the gage member threads or press-fits into the handle depending on handle design.

Key Features

• 11.34 mm diameter with 0.00508 mm tolerance for repeatable go inspection
• 10 microfinish surface finish minimizes bore wear and extends gage service life
• Tool steel construction provides hardness and dimensional stability
• 2.0000 inches overall length fits standard single-end plug gage handles
• Certificate of Accuracy with NIST traceability included
• Manufactured to ASME B89.1 standards

Compatibility

Designed for use with standard plug gage handles accepting 11.34 mm diameter gage members. Also suitable for setting micrometers, verniers, and other comparative measuring instruments requiring a traceable reference of this diameter.

Installation Notes

Plug gages should be installed and handled by qualified machinists, metrologists, or QC technicians familiar with ASME B89.1 gage-handling practices. Clean the gage member and bore thoroughly before use to prevent false readings from chips or coolant contamination. Do not force the gage member into an undersized bore, as this will damage the gage surface finish and invalidate calibration. Store the gage in its protective case when not in use to prevent corrosion and surface damage.
