Vermont Gage 111142200 Class Zz Plus Plug Gage 0.422 in

Product Description

The VERMONT GAGE 111142200 is a Class ZZ Plus plug gage designed to verify bore and hole dimensions to precise tolerances. Measuring a nominal diameter of 0.422 inches with a tolerance of 0.0002 inches, this gage delivers the accuracy required for go inspection work on production floors, inspection benches, and quality control stations. The tool steel construction and 10 microfinish surface give the gage face the hardness and smoothness needed for repeatable, reliable measurement. A Certificate of Accuracy with NIST traceability ships with each unit, supporting documentation requirements in calibrated inspection environments. Metrology technicians, machinists, and quality inspectors are the typical end users.

This plug gage is suited for go inspection applications where confirming that a drilled, bored, or reamed hole falls within a specified minimum dimension is required. It is also used to set and verify micrometers, verniers, and other measuring devices. The 0.422-inch diameter targets small-bore work common in precision machined components, hydraulic fittings, and similar applications. With an overall length of 2.0 inches, the gage handles easily in bench inspection setups as well as inline production checks.

Compatibility

Designed for use as a go inspection gage for holes and bores at 0.422-inch nominal diameter, and suitable for setting micrometers, verniers, and other calibrated measuring devices per ASME B89.1 requirements.

Installation Notes

Plug gages are handled and applied by metrology technicians, machinists, and quality inspectors — no installation in the traditional sense is required. Handle the gage by the handle or body only; avoid contact with the measuring surface to prevent contamination or wear. Store the gage in a protective case away from other metal tools to prevent nicking the finished surface. Recalibrate periodically in accordance with your facility quality management plan and applicable ASME standards.
