Vermont Gage 112306130 Class Zz Plus Plug Gage 6.13mm

Product Description

The VERMONT GAGE 112306130 is a Class ZZ Plus plug gage machined from tool steel for dimensional inspection of bored holes and machined features. It carries a 6.13 mm diameter and a tolerance of 0.00508 mm, placing it in the tighter ZZ Plus tolerance class for applications where standard Class ZZ clearance is insufficient. The working surface is finished to a 10 microfinish, reducing wear and maintaining gauge integrity over repeated use cycles. Each unit ships with a Certificate of Accuracy backed by NIST traceability, satisfying documentation requirements for calibrated measurement programs. Licensed machinists, tool-and-die workers, and quality inspection personnel are the primary users of this gauge.

This plug gage is suited for go inspection tasks in precision machining and manufacturing environments. It is used alongside micrometers, verniers, and other measuring devices to verify hole diameter conformance before assembly. Typical applications include checking bored or reamed holes in close-tolerance components where a 6.13 mm nominal diameter must be confirmed. The ASME B89.1 standard governs the tolerance and dimensional requirements met by this gage, making it appropriate for quality systems that reference that specification.

Key Features

• Class ZZ Plus tolerance class with 0.00508 mm tolerance for tight inspection requirements
• 6.13 mm diameter, 2.0 inches overall length
• Tool steel construction for durability and resistance to wear during repeated gauging cycles
• 10 microfinish working surface preserves dimensional accuracy over service life
• Includes Certificate of Accuracy with NIST traceability for calibration documentation
• Meets ASME B89.1 standard for plain plug gages

Compatibility

Designed for go inspection use with micrometers, verniers, and other measuring devices in standard precision inspection setups where a 6.13 mm Class ZZ Plus plug gage is specified per ASME B89.1.

Installation Notes

Plug gages are handled and stored by metrology technicians or quality inspection personnel, not installed in the field trade sense. Clean the gage and the hole being checked before use to prevent debris from affecting the reading or damaging the gage surface. Do not force the gage into an undersized hole, as this will cause premature wear or damage to the precision-ground diameter. Return the gage to its protective case after use and recalibrate on a schedule consistent with your quality management system requirements.
