Vermont Gage 112119520 Class Zz Plus Plug Gage 19.52mm

Product Description

The VERMONT GAGE 112119520 is a Class ZZ Plus plug gage manufactured from tool steel for dimensional go inspection work. It checks that a bored, drilled, or reamed hole meets its minimum acceptable size, confirming the workpiece will accept a mating part. The gage measures 19.52 mm in diameter with a tolerance of 0.005 mm and an overall length of 2.0000 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Machinists, quality technicians, and tool room personnel use this gage in production inspection and calibration workflows.

This plug gage is suited for go inspection applications on holes with a nominal diameter of 19.52 mm. It is used alongside micrometers, verniers, and other precision measuring devices to verify hole size in machined components. Typical applications include incoming inspection, in-process quality checks, and final acceptance testing in job shop, production, and toolroom environments. The Class ZZ Plus classification places it in a high-precision tolerance band appropriate for tight-tolerance manufacturing and gage calibration use.

Compatibility

Designed for use as a go plug gage in precision inspection setups, including applications with micrometers, verniers, and other measuring devices requiring a 19.52 mm reference standard.

Installation Notes

Plug gages are handled and used by quality technicians and machinists trained in precision measurement practices. Clean the gage and the workpiece bore before use to prevent debris from affecting the reading. Do not force the gage into a hole; apply only light, consistent hand pressure to avoid wear or damage to the gage surface. Store in a protective case away from temperature extremes to maintain dimensional accuracy.
