Vermont Gage 112106240 Class Zz Plus Plug Gage 6.24 Mm

Product Description

The VERMONT GAGE 112106240 is a Class ZZ Plus cylindrical plug gage manufactured from tool steel for dimensional go inspection of bored, drilled, and reamed holes. The gage checks a 6.24 mm diameter bore to a tolerance of 0.005 mm (0.00508 mm actual), making it suitable for precision quality control in production and inspection environments. The 10 microfinish surface provides consistent, repeatable contact across the gage diameter. At 2.0000 inches overall length, it fits standard handle sets used in tool rooms, machine shops, and metrology labs. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards.

This plug gage is intended for go inspection of holes and bores where tight dimensional tolerances are required. It is commonly used alongside set micrometers, verniers, and other precision measuring devices to verify machined features during in-process or final inspection. Typical applications include production inspection in manufacturing facilities, tool room verification, and quality assurance workflows where conformance to ASME B89.1 dimensional standards is required. The Class ZZ Plus classification indicates this is a working-grade gage appropriate for shop-floor and inspection bench use.

Key Features

• 6.24 mm inspection diameter with 0.005 mm tolerance
• 10 microfinish surface for accurate, repeatable contact
• Tool steel construction for wear resistance and dimensional stability
• Certificate of Accuracy included with NIST traceability
• Overall length of 2.0000 inches fits standard plug gage handles

Compatibility

Designed for use with standard cylindrical plug gage handles and compatible with set micrometers, verniers, and other precision measuring devices as noted in the product specifications.

Installation Notes

Plug gages should be handled by metrology or inspection personnel familiar with ASME B89.1 gauging practices. Clean the gage and bore surfaces before use to prevent debris from affecting readings or damaging the gage face. Store the gage in its protective case when not in use to preserve the microfinish surface. Periodic recalibration against NIST-traceable standards is recommended to maintain accuracy over time.
