Vermont Gage 111309050 Class Zz Plus Plug Gage

Product Description

The VERMONT GAGE 111309050 is a Class ZZ Plus plug gage designed for precision go inspection of bored, drilled, or reamed holes. It measures 0.0905 inches in diameter with a tolerance of 0.0002 inches, making it suited for high-accuracy dimensional verification in tool and die, machining, and quality control environments. The gage is manufactured from tool steel and features a 10 microfinish surface, which supports reliable, repeatable contact with the workpiece. A Certificate of Accuracy with NIST Traceability is included, meeting the documentation requirements of quality management systems. Calibration technicians and machinists working to tight tolerances rely on this gage for fast, definitive pass/fail inspection decisions.

This plug gage is intended for go inspection applications and is also suited for use in setting micrometers, verniers, and other measuring devices requiring a traceable reference standard. It is typically used in manufacturing, inspection labs, and machine shops where ASME B89.1 dimensional standards apply. Its compact overall length of 2.0 inches makes it practical for use in confined inspection setups.

Compatibility

Designed for go inspection of features at 0.0905 inches nominal diameter. Also suitable for setting micrometers, verniers, and other measuring devices requiring a traceable plug reference per ASME B89.1.

Installation Notes

Plug gages should be handled and stored by calibration technicians or trained inspection personnel following established metrology lab practices. Clean the gage and workpiece bore thoroughly before use to prevent debris from affecting readings or damaging the gage surface. Do not force the gage into a feature; go gages should enter under their own weight or with minimal hand pressure. Store in a protective case away from temperature extremes to maintain calibration integrity.
