Vermont Gage 111122500 Class Zz Plus Plug Gage 0.225 in

Product Description

The VERMONT GAGE 111122500 is a Class ZZ Plus plug gage designed to verify hole diameters with high dimensional accuracy. With a measurement diameter of 0.225 inches and a tolerance of 0.0002 inches, this gage delivers the precision required for go inspection work in production and quality control environments. Constructed from tool steel and finished to a 10 microfinish surface quality, it provides repeatable contact and long service life. A Certificate of Accuracy with NIST traceability is included, supporting documentation requirements for calibrated toolrooms and inspection departments. The overall length is 2.0 inches.

This plug gage is suited for use in go inspection applications across manufacturing and metrology environments. It is also used to calibrate and verify the accuracy of set micrometers, verniers, and other precision measuring devices. Typical users include quality control technicians, machinists, and metrology lab personnel working to ASME B89.1 standards. It is appropriate for both shop-floor inspection and controlled calibration settings where NIST-traceable documentation is required.

Compatibility

Designed for go inspection of 0.225-inch diameter features and for use as a reference standard with set micrometers, verniers, and other precision measuring devices, per the application data provided by the manufacturer.

Installation Notes

Plug gages should be handled and stored by qualified metrology or quality control personnel following ASME B89.1 guidelines. Clean the gage and the part being inspected before use to prevent measurement errors caused by debris or oil film. Do not force the gage into a hole; excessive insertion force can damage both the gage and the workpiece surface. Store in a protective case away from temperature extremes to maintain dimensional stability.
