Vermont Gage 112104260 Class Zz Plus Plug Gage 4.26mm

Product Description

The VERMONT GAGE 112104260 is a Class ZZ Plus plug gage used to inspect bore diameters and verify dimensional accuracy in machined parts. The gage measures 4.26 mm in diameter and is manufactured from tool steel, providing the hardness and wear resistance required for repetitive inspection work. It carries a tolerance of 0.00508 mm and a 10 microfinish surface finish, ensuring consistent, reliable go-inspection readings. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for quality-control environments that require documented traceability. Machinists, quality inspectors, and toolroom technicians use this type of gage daily.

This plug gage is intended for go inspection applications and is compatible with use alongside micrometers, vernier calipers, and other measuring devices for calibration and verification tasks. It fits standard plug gage handles and is appropriate for both shop-floor inspection and precision metrology setups in manufacturing environments where bore size conformance must be confirmed to tight tolerances.

Compatibility

Designed as an OEM-style replacement and standard fitment plug gage for use with go inspection setups, and compatible for setting and verifying micrometers, verniers, and other measuring devices per the application data provided.

Installation Notes

Plug gages are installed and used by quality inspectors and precision machinists; no power source is required. Handle the gage with clean, dry hands or lint-free gloves to prevent oil and debris from affecting the microfinish surface. Store the gage in its protective case when not in use to prevent corrosion or surface damage to the tool steel. Periodic recalibration against a traceable standard is recommended to maintain measurement integrity over time.
