Vermont Gage 111184800 Class Zz Plus Plug Gage 0.848 in

Product Description

The VERMONT GAGE 111184800 is a Class ZZ Plus plug gage designed for precise dimensional inspection of bored holes and machined features. Manufactured from tool steel, this plug gage measures a nominal diameter of 0.848 inches with a tolerance of 0.0002 inches, making it suitable for Go inspection applications where tight dimensional control is required. The gage surface carries a 10 microfinish rating, which supports consistent, repeatable contact with the workpiece. Each unit ships with a Certificate of Accuracy traceable to NIST, providing the documentation required for calibration records and quality management systems. Metrology technicians, machinists, and quality control professionals use this gage as part of standard inspection routines.

This plug gage is used in manufacturing and machining environments where hole diameter verification is part of the production inspection process. It is suited for Go inspection checks on components produced to ASME B89.1 standards. It also serves as a reference standard for setting micrometers, verniers, and other measuring devices to a known diameter. Typical applications include incoming inspection, in-process quality checks, and calibration of hand-measuring instruments in machine shops, toolrooms, and quality labs.

Key Features

• Class ZZ Plus tolerance grade with 0.0002 inches tolerance for precise Go inspection
• 10 microfinish surface for consistent gage-to-workpiece contact
• Tool steel construction for durability and dimensional stability
• Meets ASME B89.1 standards for gage accuracy
• Includes Certificate of Accuracy with NIST traceability for calibration documentation
• Suitable for setting micrometers, verniers, and other measuring devices

Compatibility

Designed for Go inspection of machined holes and as a reference standard for setting micrometers, verniers, and other measuring devices requiring a 0.848-inch reference diameter per ASME B89.1.

Installation Notes

Handle plug gages with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Before use, verify that the gage and workpiece are at a stable ambient temperature, as thermal expansion can affect readings at tight tolerances. Store the gage in its protective case when not in use and return it for calibration on a schedule consistent with your quality management system requirements.
