Vermont Gage 111118800 Class Zz Plus Plug Gage 0.188 in

Product Description

The VERMONT GAGE 111118800 is a Class ZZ Plus plug gage used to verify bore and hole dimensions in precision inspection work. Manufactured from tool steel, this gage measures a nominal diameter of 0.188 inches with a tolerance of 0.0002 inches and a 10 microfinish surface finish. It comes with a Certificate of Accuracy with NIST traceability, making it suitable for documented inspection programs and quality control environments. The overall length is 2.0 inches. Machinists, quality technicians, and metrologists use this type of gage to confirm dimensional conformance of drilled, reamed, or bored features before assembly or shipment.

This plug gage is intended for go inspection applications in manufacturing and metrology settings, both in production shops and inspection labs. It is also used to set and verify micrometers, verniers, and other measuring devices requiring a traceable reference. Typical applications include checking hole sizes in metal fabrication, precision machining, and toolroom environments where dimensional accuracy is critical. The Class ZZ Plus classification indicates a tighter tolerance class appropriate for reference and inspection use rather than shop-floor wear gages.

Key Features

• 0.188 inches nominal measurement diameter with 0.0002 inches tolerance
• 10 microfinish surface finish for consistent, repeatable contact
• Tool steel construction for durability and dimensional stability
• Meets ASME B89.1 standards for gage accuracy
• Includes Certificate of Accuracy with NIST traceability
• Suitable for setting micrometers, verniers, and other measuring devices

Compatibility

Designed for use as a go inspection gage and as a reference standard for setting micrometers, verniers, and other measuring devices in precision inspection and machining applications.

Installation Notes

Plug gages are handled and used by quality technicians and machinists familiar with precision measurement practices. Store the gage in its case when not in use to prevent surface damage and contamination. Clean contact surfaces before use to ensure accurate readings. Follow ASME B89.1 handling guidelines to preserve the gage's calibration integrity and surface finish.
