Vermont Gage 112112400 Class Zz Plus Plug Gage 12.4mm

Product Description

The VERMONT GAGE 112112400 is a Class ZZ Plus cylindrical plug gage used to verify bore diameters to tight dimensional tolerances. It measures 12.4 mm in diameter with a tolerance of 0.00508 mm, making it suited for high-precision go inspection work. The gage body is machined from tool steel and finished to a 10 microfinish surface quality. Overall length is 2.0 inches. Licensed metrology technicians, machinists, and quality control inspectors use this type of gage to confirm that bored or reamed features fall within acceptable dimensional limits before assembly.

This plug gage is used in manufacturing, machining, and quality assurance environments where bore acceptance requires traceable dimensional verification. It is appropriate for go inspection applications and can be used alongside set micrometers, verniers, and other calibrated measuring devices. The included Certificate of Accuracy with NIST traceability supports ISO and AS9100 quality system documentation requirements, making it well suited for aerospace, automotive, and precision machining shops.

Key Features

Compatibility

Designed for use in go inspection applications and compatible with set micrometers, verniers, and other precision measuring devices as stated by the manufacturer.

Installation Notes

Plug gages are handled and stored by calibration technicians or quality inspectors, not installed in the field. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Do not force the gage into a bore; apply only light hand pressure to avoid wear or dimensional damage. Recalibrate on a schedule consistent with your quality management system requirements.
