Vermont Gage 112319510 Class Zz Plus Plug Gage 19.51mm

Product Description

The VERMONT GAGE 112319510 is a Class ZZ Plus plug gage designed for precision dimensional inspection of bored holes and machined features. Manufactured from tool steel with a 10 micro finish, this gage checks whether a hole meets its minimum allowable size as part of a go inspection process. The nominal diameter is 19.51 mm with a tolerance of 0.005 mm (0.00508 mm actual), providing tight, reliable measurement repeatability. Each unit ships with a Certificate of Accuracy with NIST traceability, meeting ASME B89.1 standards. Machinists, quality technicians, and metrology professionals use this gage alongside micrometers, verniers, and other measuring devices to verify part conformance on the shop floor or in the inspection lab.

This plug gage is suited for go inspection applications in manufacturing, tooling, and quality control environments. It is used to verify hole diameters on machined components where tolerances are held to close limits. Typical applications include incoming inspection, in-process checks on CNC-machined parts, and calibration verification of measuring instruments such as set micrometers and verniers. The 2.0000-inch overall length provides a practical handle length for bench or in-line inspection work. This gage is appropriate for both production floor use and dedicated metrology lab settings.

Compatibility

Designed for use in go inspection applications alongside set micrometers, verniers, and other precision measuring devices as stated by the manufacturer. Suitable for any application requiring ASME B89.1 compliant plug gage inspection at a 19.51 mm nominal diameter.

Installation Notes

Plug gages should be handled by qualified metrology or quality control personnel following established inspection procedures. Store the gage in its protective case when not in use to prevent damage to the precision-ground surface. Clean the gage and the workpiece bore before use to remove chips, oil, or debris that could affect measurement results. Do not force the gage into a hole; apply only light, controlled hand pressure to avoid wear or damage to the gage or workpiece.
