Vermont Gage 111147700 Class Zz Plus Plug Gage 0.477 in

Product Description

The VERMONT GAGE 111147700 is a Class ZZ Plus plug gage used to inspect bore and hole dimensions in precision machining and metrology applications. Measuring a nominal diameter of 0.477 inches with a tolerance of 0.0002 inches, this gage provides reliable go-inspection verification for machinists, quality control technicians, and toolroom professionals. The gage is manufactured from tool steel and features a 10 microfinish surface, ensuring consistent contact and accurate measurement results. Each unit ships with a Certificate of Accuracy with NIST Traceability, supporting documentation requirements for calibrated inspection environments. Overall length is 2.0 inches.

This plug gage is suited for go inspection of machined holes, bores, and other internal features in both production and toolroom settings. It is also used for setting micrometers, verniers, and other measuring devices where a traceable dimensional reference is required. Typical users include CNC machinists, quality engineers, and toolroom technicians working in manufacturing environments where ASME B89.1 dimensional standards must be met. The compact 2.0-inch overall length makes it practical for use in both bench and floor inspection stations.

Compatibility

Designed for go inspection of holes and bores at 0.477 inches nominal diameter, and for setting micrometers, verniers, and other measuring devices requiring a traceable dimensional reference.

Installation Notes

Plug gages of this type are handled and used by quality control technicians and toolroom machinists. Store and handle the gage with clean hands or lint-free gloves to prevent corrosion from skin contact. Do not force the gage into a bore; apply only light, consistent hand pressure during inspection. Periodic cleaning and recalibration in accordance with ASME B89.1 and your facility quality plan will maintain measurement integrity.
