Vermont Gage 112300530 Class Zz Plus Plug Gage 0.53mm

Product Description

The VERMONT GAGE 112300530 is a Class ZZ Plus plug gage designed for precision dimensional inspection of small-diameter bores and holes. It measures 0.53 mm in diameter with a tolerance of 0.005 mm (0.00508 mm actual), making it suited for go-inspection work where tight dimensional control is required. Constructed from tool steel with a 10 microfinish surface coating, it provides consistent, repeatable measurements. Every unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Overall length is 2.0 inches. Machinists, quality technicians, and metrologists use this gage to verify hole diameters on precision components before assembly or final inspection.

This plug gage is intended for go inspection applications in machine shops, manufacturing facilities, and quality control environments. It is compatible with standard gage handle systems and is used alongside micrometers, verniers, and other precision measuring devices to confirm bore acceptance. Its 0.53 mm diameter makes it applicable for small-bore inspection tasks common in instrument manufacturing, medical device production, and aerospace component verification.

Key Features

• Class ZZ Plus tolerance classification with 0.005 mm tolerance for demanding go-inspection use
• Tool steel construction for hardness and dimensional stability over repeated use
• 10 microfinish surface coating ensures smooth, consistent contact with the bore surface
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 dimensional gage standards
• Compact 2.0-inch overall length for use in standard small-gage handle systems

Compatibility

Designed for use with standard plug gage handle systems for go inspection of 0.53 mm diameter bores. Compatible with micrometers, verniers, and other precision measuring devices as a reference or check standard per the supplier application notes.

Installation Notes

Plug gages of this type are handled and used by quality technicians and machinists in accordance with metrology best practices. Clean the gage and bore thoroughly before use to prevent debris from affecting readings or damaging the gage surface. Never force a plug gage into a bore; light, consistent hand pressure is appropriate. Store the gage in its protective case and avoid contact with other metal tools to preserve the 10 microfinish surface and dimensional integrity.
