Vermont Gage 112105300 Class Zz Plus Plug Gage 5.3 Mm

Product Description

The VERMONT GAGE 112105300 is a Class ZZ Plus plug gage designed for precision dimensional inspection of hole diameters. Built from tool steel with a 10 microfinish surface coating, this gage checks a nominal diameter of 5.3 mm with a tolerance of 0.00508 mm, making it suitable for high-accuracy go inspection work. Each unit ships with a Certificate of Accuracy with NIST traceability, confirming conformance to ASME B89.1 standards. Dimensional inspection professionals and quality control technicians rely on plug gages like this one to verify bore sizes quickly and repeatably on the shop floor or in the inspection lab.

This plug gage is used in go inspection applications to confirm that a bore or hole meets its minimum size requirement. It is appropriate for use alongside set micrometers, verniers, and other measuring devices in manufacturing, machining, and quality assurance environments. The 5.3 mm diameter and compact overall length of 2.0000 inches make it well suited for benchtop inspection setups in both production and tool room settings. Machinists, quality technicians, and metrologists handling close-tolerance work in metalworking and related industries are the primary users.

Key Features

• 5.3 mm nominal diameter with 0.00508 mm tolerance for precise go inspection
• 10 microfinish surface coating for consistent, low-friction gage contact
• Tool steel construction for hardness and dimensional stability
• Complies with ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability
• Overall length of 2.0000 inches for easy handling in standard gage handles or holders

Compatibility

Designed for use as a go inspection gage with set micrometers, verniers, and other precision measuring devices where 5.3 mm bore verification is required per ASME B89.1.

Installation Notes

Plug gages are typically handled by quality technicians and metrologists following standard metrology practices. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Clean the gage surface before each use to remove debris or oils that could affect measurement accuracy. Do not force the gage into a bore; apply only light, consistent hand pressure consistent with proper go gage technique.
