Vermont Gage 112104160 Class Zz Plus Plug Gage 4.16mm

Product Description

The VERMONT GAGE 112104160 is a Class ZZ Plus plug gage designed for precise dimensional inspection of bored holes and machined features. Built from tool steel with a 10 microfinish surface coating, this gage delivers reliable pass/fail results in go inspection workflows. The 4.16 mm diameter and 0.005 mm tolerance make it suited for close-tolerance quality control operations. Machinist technicians and quality control inspectors use this gage in conjunction with set micrometers, verniers, and other measuring devices to verify bore dimensions on production and maintenance floors. Each unit ships with a Certificate of Accuracy with NIST Traceability.

This plug gage is intended for use in dimensional inspection applications across manufacturing, toolroom, and maintenance environments. It is well suited to verifying 4.16 mm diameter features on machined components where Class ZZ Plus tolerances are specified. The compact overall length of 2.0000 inches allows use in confined inspection setups. Typical users include machinists, quality technicians, and metrology lab personnel who require documented traceability for audit and compliance purposes.

Key Features

• Class ZZ Plus tolerance class with 0.005 mm tolerance for close-tolerance go inspection
• Tool steel construction for wear resistance and dimensional stability
• 10 microfinish surface coating ensures consistent gage contact with inspected bore
• Includes Certificate of Accuracy with NIST Traceability for documented calibration records
• Conforms to ASME B89.1 standards for plain plug gages
• Compatible with set micrometers, verniers, and comparable measuring devices

Compatibility

Designed for go inspection use with set micrometers, verniers, and other measuring devices as stated by the manufacturer. Suitable for any application requiring a Class ZZ Plus plug gage at 4.16 mm diameter per ASME B89.1.

Installation Notes

Plug gages are handled and used by qualified machinists or metrology personnel following standard inspection procedures. Keep the gage clean and lightly oiled when not in use to prevent corrosion of the tool steel body. Never force the gage into a bore; excessive insertion force can damage both the gage and the workpiece. Store in a protective case away from temperature extremes to maintain dimensional accuracy and protect the NIST-traceable calibration.
