Vermont Gage 112114500 Class Zz Plus Plug Gage 14.5mm

Product Description

The VERMONT GAGE 112114500 is a Class ZZ Plus cylindrical plug gage designed for go inspection of bored, drilled, and reamed holes. Manufactured from tool steel with a 10 microfinish surface coating, this gage measures 14.5 mm in diameter and holds a tolerance of 0.005 mm (0.00508 mm actual). The overall length is 2.0000 inches. It ships with a Certificate of Accuracy traceable to NIST, making it suitable for use in calibrated inspection environments. Machinists, quality control technicians, and toolroom professionals use plug gages like this one to verify hole dimensions against specification without relying on variable measuring instruments.

This plug gage is suited for go inspection tasks in production and quality lab settings. It works alongside set micrometers, verniers, and other precision measuring devices to confirm that machined hole diameters fall within acceptable limits. Typical applications include incoming inspection, in-process quality checks, and final part verification on machined components in manufacturing environments requiring traceability to national standards.

Key Features

• Class ZZ Plus tolerance class — 0.005 mm (0.00508 mm) tolerance for go inspection use
• 14.5 mm diameter — precision-ground tool steel construction
• 10 microfinish surface coating for consistent gage contact and wear resistance
• Certificate of Accuracy included with NIST traceability
• Conforms to ASME B89.1 standards
• Overall length of 2.0000 inches — compact handle for bench and in-line use

Compatibility

Designed as a go inspection plug gage compatible for use with set micrometers, verniers, and other precision measuring devices requiring a 14.5 mm reference diameter.

Installation Notes

Plug gages are handled and used by quality control technicians and toolroom machinists. Clean the gage and the workpiece bore before use to prevent debris from affecting the measurement. Store the gage in its case or designated holder when not in use to protect the ground surface. Do not force the gage into a hole — excessive insertion force can damage both the gage and the workpiece and will produce unreliable inspection results.
