Vermont Gage 112314790 Class Zz Plus Plug Gage 14.79mm

Product Description

The VERMONT GAGE 112314790 is a Class ZZ Plus plug gage used to verify bore diameters in precision machining and quality-control workflows. Designed for Go inspection applications, this gage checks that a machined hole meets minimum size requirements before a part advances in production. It is manufactured from tool steel with a 10 micro-inch finish and holds a tolerance of 0.00508 mm, making it suitable for close-tolerance work. Every unit ships with a Certificate of Accuracy traceable to NIST standards. Machinists, toolroom technicians, and quality inspectors are the primary users. The overall length is 2.0000 inches.

This plug gage is used in production inspection, tool and die shops, and quality labs where hole size conformance must be verified against a dimensional standard. At 14.79 mm nominal diameter, it covers a common metric bore size found in precision machined components. It is also appropriate for setting and verifying micrometers, verniers, and other measuring devices to confirm calibration against a known dimension. Suitable for both shop-floor and lab environments.

Key Features

• Class ZZ Plus tolerance rating at 0.00508 mm for precise Go inspection
• Tool steel construction for wear resistance and dimensional stability
• 10 micro-inch coating finish for consistent gage surface quality
• Certificate of Accuracy included with NIST traceability
• Meets ASME B89.1 standards for plain gage design
• Suitable for use with micrometers, verniers, and other measuring instruments

Compatibility

Designed for Go inspection use with micrometers, verniers, and other precision measuring devices requiring a traceable reference standard at 14.79 mm diameter.

Installation Notes

Plug gages are handled and used by machinists and quality technicians in inspection environments. Keep the gage clean and lightly oiled when not in use to prevent corrosion of the tool steel surface. Do not force the gage into a bore; if resistance is felt, the hole is undersized and should be returned for additional machining. Store in a protective case away from temperature extremes to maintain dimensional accuracy.
