Vermont Gage 111338450 Class Zz Plus Plug Gage 0.3845 in

Product Description

The VERMONT GAGE 111338450 is a Class ZZ Plus plug gage designed to verify hole diameters to a measured size of 0.3845 inches. Machined from tool steel with a 10 microfinish surface coating, this gage delivers consistent, reliable dimensional inspection. It carries a Certificate of Accuracy with NIST traceability and conforms to ASME B89.1 standards. At an overall length of 2.0 inches and a tolerance of 0.0002 inches, it provides the accuracy required for go inspection tasks in precision manufacturing and quality control environments. Licensed metrology technicians, machinists, and quality inspectors are the primary users of this instrument.

This plug gage is suited for go inspection of bored, drilled, or reamed holes measuring 0.3845 inches in diameter. It is also appropriate for setting and verifying micrometers, verniers, and other measuring devices requiring a traceable reference standard. Typical applications include incoming inspection, in-process quality checks, and final part verification in job shops, production facilities, and toolrooms where dimensional compliance to print is required.

Key Features

• NIST-traceable Certificate of Accuracy included with each gage
• Conforms to ASME B89.1 dimensional gage standards
• Tool steel construction for wear resistance and long service life
• 10 microfinish surface coating for smooth, consistent contact
• Tolerance of 0.0002 inches for precise Class ZZ Plus classification
• Suitable for setting micrometers, verniers, and other precision measuring instruments

Compatibility

Designed for go inspection of holes with a nominal diameter of 0.3845 inches, and for use as a reference standard when setting micrometers, verniers, and comparable measuring devices.

Installation Notes

Handle plug gages with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Before use, verify the gage and workpiece are at the same ambient temperature to eliminate thermal expansion errors. Do not force the gage into an undersized hole; forcing causes gage wear and inaccurate readings. Store in the provided case or a clean, dry environment when not in use.
