Vermont Gage 111133800 Class Zz Plus Plug Gage 0.338 in

Product Description

The VERMONT GAGE 111133800 is a Class ZZ Plus plug gage designed for precision dimensional inspection of bores, holes, and machined features. It measures a nominal diameter of 0.338 inches with a tolerance of 0.0002 inches and is manufactured from tool steel for long service life. The gage carries a 10 microfinish surface finish on the measuring member, delivering consistent, repeatable contact with the workpiece. It ships with a Certificate of Accuracy traceable to NIST, making it suitable for calibrated inspection environments. Machinists, quality control technicians, and tool room personnel use this type of gage for go inspection of precision bores.

This plug gage is used in manufacturing, tool rooms, and quality inspection stations where accurate bore and hole acceptance testing is required. Its 0.338-inch diameter makes it appropriate for inspecting precision-machined holes in metal components across a range of industries. The gage is also referenced for setting micrometers, verniers, and other measuring devices. It conforms to ASME B89.1 standards, which governs dimensional gage design and accuracy requirements for plain plug gages used in production and inspection applications.

Compatibility

Designed for go inspection of bores and holes at 0.338 inches nominal diameter, and suitable for use as a setting standard for micrometers, verniers, and other measuring devices per ASME B89.1.

Installation Notes

Plug gages should be handled and stored per ASME B89.1 guidelines to prevent damage to the precision-ground measuring surface. Clean the gage and the bore being inspected before use to avoid false readings caused by debris or coolant residue. Do not force the gage member into a bore; apply light hand pressure only to avoid damaging the gage or the workpiece. Periodic recalibration against a traceable standard is recommended to maintain measurement integrity.
