Vermont Gage 112311210 Class Zz Plus Plug Gage 11.21mm

Product Description

The VERMONT GAGE 112311210 is a Class ZZ Plus plug gage ground to an 11.21 mm diameter with a tolerance of 0.00508 mm. It is manufactured from tool steel and finished to a 10 microfinish surface for consistent, repeatable contact. This gage is used for go inspection to verify that a bore or hole meets minimum acceptable size requirements. Licensed calibration technicians, machinists, and quality control inspectors use this type of gage as part of incoming, in-process, and final inspection routines. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documentation requirements in ISO and ASME-compliant quality systems.

This plug gage is designed for use in precision measurement applications including go inspection, setting micrometers, verniers, and other measuring devices. It is suited for machine shops, tool rooms, and manufacturing quality labs where bore size verification is required at the 11.21 mm nominal diameter. The overall length of 2.0000 inches makes it compatible with standard handle systems used in bench and floor inspection setups. Compliance with ASME B89.1 ensures the gage meets nationally recognized dimensional standards for plain plug gages.

Key Features

• Tool steel construction for wear resistance and dimensional stability
• 10 microfinish surface coating for consistent gage contact
• Includes Certificate of Accuracy with NIST traceability
• Meets ASME B89.1 standard for plain plug gages
• Overall length of 2.0000 inches compatible with standard gage handle systems

Compatibility

Designed for go inspection use with standard plug gage handles and applicable for setting micrometers, verniers, and other measuring devices requiring an 11.21 mm reference diameter.

Installation Notes

Plug gages are handled and used by calibration technicians and quality inspectors following ASME B89.1 practices. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Do not force the gage through an undersized bore, as this will damage the gage and invalidate the inspection result. Store in a protective case away from temperature extremes to maintain dimensional accuracy.
