Vermont Gage 111333950 Class Zz Plus Plug Gage 0.3395 in

Product Description

The VERMONT GAGE 111333950 is a Class ZZ Plus plug gage designed for precise go inspection of bored, drilled, and reamed holes. It measures a nominal diameter of 0.3395 inches with a tolerance of 0.0002 inches, making it suitable for applications where close dimensional verification is required. The gage is machined from tool steel and features a 10 microfinish surface, which supports accurate and repeatable contact with the workpiece. Each unit ships with a Certificate of Accuracy that carries NIST traceability, meeting the documentation requirements common in quality-controlled manufacturing and inspection environments. Machinists, quality technicians, and tool-and-die professionals are the primary users.

This plug gage is used in machine shops, manufacturing facilities, and inspection departments where hole diameter verification is part of standard quality control workflow. It is appropriate for go inspection use with setting micrometers, verniers, and other measuring devices as noted in the product specifications. The 2.0-inch overall length provides a practical handling size for bench and floor inspection tasks. It conforms to ASME B89.1 standards, making it suitable for facilities that require compliance with recognized dimensional metrology standards.

Installation Notes

Plug gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion and dimensional contamination from skin oils. Store the gage in its protective case when not in use and allow it to thermally stabilize to shop temperature before use to avoid false readings caused by thermal expansion. Calibration intervals should follow the facility quality management plan and applicable metrology standards. Do not force the gage into an undersized hole, as this can damage both the gage and the workpiece.
