Vermont Gage 111304750 Class Zz Plus Plug Gage 0.0475 in

Product Description

The VERMONT GAGE 111304750 is a Class ZZ Plus plug gage used to verify bore and hole dimensions in precision inspection work. The gage measures a nominal diameter of 0.0475 inches with a tolerance of 0.0002 inches, making it suitable for close-tolerance go inspection applications. The measuring surface carries a 10 microfinish, providing a smooth contact face that minimizes wear and measurement error. Overall length is 2.0 inches. Manufactured from tool steel for durability under repeated use. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Machinists, quality control technicians, and tool-and-die professionals are the primary users.

This plug gage is used in go inspection routines to confirm that a hole or bore meets minimum size requirements. It is appropriate for use in machine shops, production floors, and metrology labs handling small-diameter precision components. The gage is also suited for setting and verifying micrometers, verniers, and other measuring devices where a certified reference standard is needed. Applications span both light manufacturing and high-precision industries where dimensional conformance is documented and auditable.

Key Features

• 0.0475 inch nominal measurement diameter for small-bore go inspection
• 0.0002 inch tolerance per Class ZZ Plus specification
• 10 microfinish surface for accurate, repeatable contact
• Tool steel construction for wear resistance and dimensional stability
• Certificate of Accuracy included with NIST traceability
• Meets ASME B89.1 standards for plain plug gages

Compatibility

Designed for go inspection use with micrometers, verniers, and other precision measuring devices requiring a certified reference plug at 0.0475 inch diameter.

Installation Notes

Plug gages are handled and used by qualified metrology or quality control personnel. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Do not force the gage into a bore; excessive insertion force can damage the gage and produce inaccurate readings. Store in a protective case away from temperature extremes to maintain dimensional stability.
