Vermont Gage 112114720 Class Zz Plus Plug Gage 14.72mm

Product Description

The VERMONT GAGE 112114720 is a Class ZZ Plus cylindrical plug gage manufactured from tool steel and designed for go inspection of precision bored holes and machined features. With a nominal diameter of 14.72 mm and a tolerance of 0.00508 mm, it delivers the tight dimensional control required in production and quality-assurance workflows. The 10 Micro coating finish protects the gage surface and extends service life under regular shop-floor use. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documentation requirements in ISO and AS9100 quality systems. Machinists, quality technicians, and metrology lab personnel are the primary users of this type of precision gage.

This plug gage is used to verify that a drilled, reamed, or bored hole meets its minimum acceptable diameter before a part advances to the next manufacturing stage. It is suited for use alongside set micrometers, verniers, and other measuring devices in both job-shop and production environments. The go-inspection application confirms dimensional conformance and helps catch undersized features before assembly. At 2.0000 inches overall length, the handle provides adequate grip for bench-top and in-process inspection tasks on small to medium workpieces.

Key Features

• 14.72 mm nominal diameter with 0.00508 mm Class ZZ Plus tolerance for high-accuracy go inspection
• Tool steel construction for durability and dimensional stability under repeated use
• 10 Micro coating finish protects the gage surface and reduces wear
• Includes Certificate of Accuracy with NIST traceability to satisfy quality-system documentation requirements
• Conforms to ASME B89.1 standards for plain plug gages
• 2.0000-inch overall length provides balanced handling for bench and in-process inspection

Compatibility

Designed for use as a go plug gage in quality inspection setups alongside set micrometers, verniers, and other precision measuring devices requiring a Class ZZ Plus reference standard at 14.72 mm diameter.

Installation Notes

Plug gages should be handled by metrology or quality personnel familiar with ASME B89.1 gage-use practices. Clean and inspect the gage and the workpiece bore before each use to prevent debris from causing false readings or gage damage. Never force the gage into a hole; apply only light, consistent hand pressure aligned with the bore axis. Store the gage in its protective case when not in use to prevent corrosion and surface damage.
