Vermont Gage 112108240 Class Zz Plus Plug Gage 8.24mm

Product Description

The VERMONT GAGE 112108240 is a Class ZZ Plus plug gage machined from tool steel for precision bore inspection and dimensional verification. It carries a diameter of 8.24 mm and holds a tolerance of 0.00508 mm, making it suitable for go inspection applications where tight measurement accuracy is required. The 10 microfinish surface coating reduces wear and maintains gage integrity over repeated use cycles. Overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting quality documentation requirements in calibrated shop environments. Licensed metrologists, quality technicians, and machining professionals use this gage as part of incoming and in-process inspection workflows.

This plug gage is used in machine shops, manufacturing facilities, and quality labs where hole diameter must be verified against a defined tolerance band. It is suited for use alongside micrometers, verniers, and other precision measuring devices as a reference or go-inspection tool. The 8.24 mm diameter targets bore sizes in that metric range, commonly encountered in precision component manufacturing, tooling verification, and fixture qualification. Conformance to ASME B89.1 makes it appropriate for environments requiring traceable, standards-based dimensional inspection.

Key Features

• 8.24 mm diameter with 0.00508 mm tolerance for precise go inspection
• Tool steel construction for durability and dimensional stability
• 10 microfinish surface coating minimizes wear on repeated insertions
• Meets ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability for quality documentation
• Overall length of 2.0000 inches suits standard plug gage handles and holders

Compatibility

Designed for use as a go inspection plug gage with standard gage handles and compatible with micrometers, verniers, and other measuring devices where an 8.24 mm diameter reference is required.

Installation Notes

Plug gages should be handled and stored according to ASME B89.1 guidelines to preserve calibration integrity. Clean the gage and bore surfaces before inspection to prevent false readings caused by debris or coolant residue. Do not force the gage into an undersized bore, as this can damage both the gage and the workpiece. Periodic recalibration against NIST-traceable standards is recommended to maintain measurement confidence in production environments.
