Vermont Gage 111303250 Class Zz Plus Plug Gage 0.0325 in

Product Description

The VERMONT GAGE 111303250 is a Class ZZ Plus cylindrical plug gage used to verify bore and hole diameters to tight tolerances in production and inspection environments. The gage measures 0.0325 inches in diameter with a tolerance of 0.0002 inches, making it suited for precision go-inspection tasks where dimensional accuracy is critical. Manufactured from tool steel, the gage has a 10 microfinish surface for consistent, repeatable contact. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documentation requirements in quality systems. Machinists, toolroom technicians, and quality inspection personnel are the primary users of this type of gage.

This plug gage is intended for go inspection applications where confirming minimum acceptable hole size is required. It is also used to calibrate and verify set micrometers, verniers, and other precision measuring devices. The 0.0325-inch diameter and overall length of 2.0 inches make it appropriate for small-bore inspection in precision machining, toolroom, and manufacturing quality control settings. Compliance with ASME B89.1 ensures the gage meets recognized dimensional metrology standards for this class of inspection tooling.

Key Features

• Includes Certificate of Accuracy with NIST traceability for quality documentation
• Meets ASME B89.1 standard for dimensional metrology

Compatibility

Designed for go inspection of bores and holes at 0.0325 inches diameter, and for setting and verifying micrometers, verniers, and other precision measuring devices per the stated application data.

Installation Notes

Plug gages are handled and used by quality technicians and toolroom machinists following standard metrology practices. Store the gage in its protective case and apply a light coat of instrument oil when not in use to prevent corrosion of the tool steel. Do not force the gage into a bore; apply only light, consistent hand pressure to avoid damage to the gage or workpiece. Calibration intervals should follow your facility quality plan and applicable metrology standards.
