Vermont Gage 112313790 Class Zz Plus Plug Gage 13.79mm

Product Description

The VERMONT GAGE 112313790 is a Class ZZ Plus plug gage designed for precise hole-diameter verification in production and quality-control environments. Machined from tool steel with a 10 microfinish surface coating, this gage checks a 13.79 mm nominal diameter with a tolerance of 0.00508 mm. It is configured for Go inspection, confirming that a bored, reamed, or drilled hole falls within the minimum acceptable limit. A Certificate of Accuracy with NIST traceability ships with each unit, satisfying documentation requirements for ISO-compliant and AS9100 shop environments. The overall handle length is 2.0000 inches, keeping it compact for bench or floor use.

This plug gage is suited for setting and verifying micrometers, verniers, and other measuring devices, as well as direct Go inspection of machined holes. It is commonly used in precision machining, toolroom inspection, and quality assurance applications across metalworking, aerospace, and general manufacturing. Machinists, quality technicians, and metrologists are the primary users. The gage is appropriate for both incoming inspection and in-process verification wherever ASME B89.1 conformance is required.

Key Features

• Class ZZ Plus tolerance rating for Go inspection of 13.79 mm diameter holes
• Tolerance of 0.00508 mm for high-accuracy dimensional verification
• 10 microfinish surface coating reduces wear and protects gage surface
• Tool steel construction for durability in production environments
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 dimensional standards

Compatibility

Designed for Go inspection of 13.79 mm diameter bores and for setting micrometers, verniers, and other measuring devices per ASME B89.1 requirements.

Installation Notes

Plug gages should be handled and stored by qualified quality technicians or metrologists following ASME B89.1 handling guidelines. Keep the gage clean and lightly oiled when not in use to prevent corrosion of the tool steel body. Do not force the gage into a bore; apply light, controlled hand pressure only. Verify the gage calibration status against its Certificate of Accuracy before placing it into service.
