Vermont Gage 112306730 Class Zz Plus Plug Gage 6.73mm

Product Description

The VERMONT GAGE 112306730 is a Class ZZ Plus cylindrical plug gage machined from tool steel for dimensional inspection of bored holes, machined features, and similar precision work. The gage checks a nominal diameter of 6.73 mm with a tolerance of 0.00508 mm, making it suitable for go-inspection applications where tight dimensional control is required. The working surface carries a 10 microfinish, which reduces wear on the gage and the part being checked. An overall length of 2.0000 inches positions the gage comfortably in a standard gage handle. A Certificate of Accuracy with NIST Traceability ships with each unit.

This plug gage is used in production and inspection environments wherever a 6.73 mm bore or feature must be verified against a known standard. Typical applications include go-inspection of drilled or reamed holes in metal and plastic parts. The gage also serves as a setting standard for micrometers, verniers, and other measuring devices that require a traceable reference. It is suited to machine shops, quality labs, and field inspection work performed by machinists, quality technicians, and metrology professionals.

Key Features

• 6.73 mm nominal diameter with 0.00508 mm Class ZZ Plus tolerance for precise go-inspection
• 10 microfinish working surface minimizes wear and maintains gage accuracy over repeated use
• Tool steel construction provides hardness and dimensional stability
• ASME B89.1 compliant, meeting recognized dimensional metrology standards
• Includes Certificate of Accuracy with NIST Traceability for calibration documentation requirements
• Compact 2.0000-inch overall length fits standard gage handles

Compatibility

Designed as an OEM-style plug gage for use with standard gage handle systems and as a setting reference for micrometers, verniers, and other measuring devices requiring a traceable 6.73 mm standard.

Installation Notes

Plug gages are handled and used by machinists and quality technicians; no installation in the traditional sense applies. Store the gage in its protective case when not in use to prevent nicks or corrosion on the lapped surface. Clean the gage and the part being inspected before use to avoid false readings caused by chips or debris. Never force the gage into an undersized feature, as this will damage the lapped surface and invalidate calibration.
