Vermont Gage 112314050 Class Zz Plus Plug Gage 14.05mm

Product Description

The VERMONT GAGE 112314050 is a Class ZZ Plus cylindrical plug gage designed for precise go-inspection of bored, reamed, and machined holes with a nominal diameter of 14.05 mm. Manufactured from tool steel with a 10 microfinish surface, it delivers a tolerance of 0.005 mm (0.00508 mm actual) to verify that a workpiece hole meets minimum acceptable size requirements. The gage ships with a Certificate of Accuracy traceable to NIST, making it suitable for use in quality-controlled shop environments, calibration labs, and toolroom inspection stations. Machinists, quality technicians, and metrology professionals use this type of gage as a fast, reliable attribute-inspection tool.

This plug gage is intended for go-inspection applications where hole diameter conformance must be confirmed quickly and consistently. It is compatible with standard gage handle sets and is also referenced when setting and verifying micrometers, verniers, and other measuring devices. The overall length of 2.0000 inches suits typical hand-held inspection workflows on production floors and in quality labs handling small-to-medium precision components.

Key Features

• Class ZZ Plus tolerance of 0.005 mm for reliable go-inspection accuracy
• Tool steel construction provides wear resistance and dimensional stability
• 10 microfinish surface finish for smooth, repeatable insertion into the workpiece
• Includes Certificate of Accuracy with NIST traceability for audit and calibration records
• Conforms to ASME B89.1 standards for plain gages
• Compatible with standard plug gage handles for ergonomic use

Compatibility

Designed for use with standard cylindrical plug gage handles and suitable for setting micrometers, verniers, and other measuring devices requiring a 14.05 mm reference diameter.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no tools or power sources are required for inspection use. Keep the gage clean and lightly oiled when stored to prevent corrosion on the tool steel body. Do not force the gage into an undersized hole, as this can damage both the gage and the workpiece surface. Periodic recalibration against NIST-traceable standards is recommended to maintain measurement integrity.
