Vermont Gage 111347250 Class Zz Plus Plug Gage

Product Description

The VERMONT GAGE 111347250 is a Class ZZ Plus plug gage designed for precision dimensional inspection of bored, drilled, and reamed holes. Manufactured from tool steel with a 10 microfinish surface, this gage checks hole diameters at 0.4725 inches with a tolerance of 0.0002 inches. It ships with a Certificate of Accuracy traceable to NIST, confirming conformance to ASME B89.1 standards. Machinists, quality technicians, and metrologists rely on plug gages like this one to verify that manufactured features fall within specified tolerances before parts advance through production or ship to the customer.

The 111347250 is suited for go inspection applications in manufacturing and quality control environments. Its 2.0-inch overall length provides a comfortable grip and consistent insertion into the feature being measured. It is also compatible with setup and calibration tasks for set micrometers, verniers, and other precision measuring devices. Typical users include CNC machinists, quality lab technicians, and toolroom professionals working to ASME or equivalent dimensional standards in both job shop and production settings.

• Tool steel construction provides durability for repeated use in production environments
• Includes Certificate of Accuracy with NIST traceability, meeting ASME B89.1 requirements
• 2.0-inch overall length suits standard plug gage handles and direct hand use
• Suitable for calibrating and setting micrometers, verniers, and similar measuring instruments

Compatibility

Designed for go inspection of 0.4725-inch nominal diameter features and for setting and verifying set micrometers, verniers, and other precision measuring devices.

Installation Notes

Plug gages should be handled by quality technicians or toolroom professionals familiar with ASME B89.1 dimensional standards. Clean the gage and the workpiece feature before use to prevent debris from affecting measurement results. Store the gage in its protective case when not in use to preserve the surface finish and dimensional integrity. Avoid dropping or stacking with other tools, as impact damage will compromise accuracy.
