Vermont Gage 111338350 Class Zz Plus Plug Gage 0.3835 in

Product Description

The VERMONT GAGE 111338350 is a Class ZZ Plus plug gage ground to a nominal diameter of 0.3835 inches for use in precision dimensional inspection. Made from tool steel with a 10 microfinish surface, it delivers consistent, repeatable measurements in go-inspection applications. The gage ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Licensed metrologists, quality technicians, and machine shop inspectors rely on this type of gage to verify bore diameters and confirm part conformance on the production floor or in the calibration lab.

This plug gage is suited for checking bore diameters in machined components, tooling fixtures, and manufactured assemblies where tight tolerances are critical. It is also used to calibrate and set micrometers, verniers, and other measuring devices. The Class ZZ Plus tolerance classification makes it appropriate for inspection work requiring a higher level of accuracy than standard workshop gages, including incoming inspection, first-article inspection, and process control checks in both job shop and production environments.

Key Features

• Nominal measurement diameter of 0.3835 inches for precise bore verification
• Class ZZ Plus tolerance of 0.0002 inches for high-accuracy inspection
• Tool steel construction with 10 microfinish surface for durability and consistent contact
• Includes Certificate of Accuracy with NIST traceability
• Meets ASME B89.1 dimensional gage standards
• Overall length of 2.0 inches for convenient hand use

Compatibility

Designed for go-inspection applications and for setting micrometers, verniers, and other precision measuring devices requiring a 0.3835-inch reference diameter.

Installation Notes

Plug gages are handled and used by quality technicians and metrology personnel — no power tools or trade licensing are required for standard inspection use. Clean the gage and the bore being checked before use to prevent debris from affecting measurement accuracy. Store the gage in its protective case when not in use and avoid dropping or contacting the gage surface against hard objects, as surface damage will invalidate the tolerance class. Periodic recalibration against NIST-traceable standards is recommended to maintain measurement integrity.
