Vermont Gage 112311390 Class Zz Plus Plug Gage 11.39mm

Product Description

The VERMONT GAGE 112311390 is a Class ZZ Plus plug gage ground from tool steel to a 10 microfinish surface. It measures 11.39 mm in diameter with a tolerance of 0.00508 mm, making it suitable for high-repeatability go inspection tasks. Overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy that carries NIST traceability, meeting ASME B89.1 standards. Machinists, quality technicians, and metrology professionals use this gage to verify bore and hole dimensions on production and inspection floors.

This plug gage is used in go inspection applications where bore diameter verification is required to tight tolerances. It is compatible with use alongside set micrometers, verniers, and other precision measuring devices. Typical applications include incoming inspection, in-process quality checks, and final acceptance gauging in manufacturing environments. The 11.39 mm size fits a range of machined bores and drilled holes commonly encountered in general machining and precision fabrication work.

Compatibility

Designed for use in go inspection of 11.39 mm diameter bores and holes. Compatible with set micrometers, verniers, and other precision measuring devices as stated by the manufacturer.

Installation Notes

Plug gages are handled and used by quality technicians and machinists following standard metrology practices. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Do not force the gage into a bore; apply only light, consistent hand pressure to avoid measurement error or surface damage. Store in the provided case or a clean, dry location away from other tooling to protect the finished surface.
