Vermont Gage 112104600 Class Zz Plus Plug Gage 4.6mm

Product Description

The VERMONT GAGE 112104600 is a Class ZZ Plus cylindrical plug gage designed for precision bore and hole inspection in quality-control and metrology applications. It measures 4.60 mm in diameter with a tolerance of 0.00508 mm, making it suitable for go-inspection work where tight dimensional verification is required. Manufactured from tool steel and finished to a 10 microfinish surface quality, this gage delivers consistent, repeatable results. Each unit ships with a Certificate of Accuracy traceable to NIST, satisfying documentation requirements for ISO and AS9100 quality systems. Overall length is 2.0000 inches. Installed and used by machinists, quality technicians, and calibration professionals.

This plug gage is used in go inspection routines to verify that a bore or hole meets its minimum acceptable size. It is appropriate for use in production floor inspection, incoming inspection, and tool-room metrology environments. Compatible with standard gage handle systems, it is also used alongside set micrometers, vernier calipers, and other comparative measuring devices where a reference standard is needed. Typical applications include aerospace, automotive, and general precision manufacturing facilities where ASME B89.1 compliance is required.

Key Features

• 4.60 mm diameter with 0.00508 mm tolerance for precise go-inspection gauging
• Class ZZ Plus tolerance classification per ASME B89.1
• Tool steel construction for wear resistance and dimensional stability
• 10 microfinish surface for accurate, repeatable contact measurement
• Includes Certificate of Accuracy with NIST traceability for quality documentation

Compatibility

Designed for use as a go plug gage in standard gage handle systems and as a reference standard for set micrometers, verniers, and other comparative measuring devices.

Installation Notes

Plug gages should be handled by calibration technicians or quality inspection personnel familiar with ASME B89.1 measurement practices. Store the gage in its protective case when not in use to prevent damage to the finished surface. Clean the gage and the bore being checked before use to avoid false readings caused by debris or oil contamination. Do not force the gage into a bore; excessive insertion force can damage both the gage and the workpiece.
