Vermont Gage 111168700 Class Zz Plus Plug Gage 0.687 in

Product Description

The VERMONT GAGE 111168700 is a Class ZZ Plus plug gage designed for go inspection of bored, drilled, and reamed holes requiring precise dimensional verification. Manufactured from tool steel with a 10 microfinish surface, this gage checks that a feature meets its minimum size requirement. At 0.687 inches diameter and 2.0 inches overall length, it fits standard gage handles for efficient single-hand operation. It conforms to ASME B89.1 and ships with a Certificate of Accuracy with NIST traceability, making it suitable for quality-control environments where documented calibration records are required.

This plug gage is used in precision machining, toolroom, and inspection environments to verify hole diameters on machined components. Typical applications include go inspection of workpieces held to tight tolerances, as well as setting and checking micrometers, verniers, and other measuring devices. The 0.0002 inch tolerance class ensures reliable acceptance criteria for high-precision manufacturing processes where dimensional repeatability is critical.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for precise go inspection
• 10 microfinish surface finish for smooth, repeatable gage entry
• Tool steel construction for wear resistance and dimensional stability
• Conforms to ASME B89.1 dimensional standards
• Includes Certificate of Accuracy with NIST traceability for documented calibration records
• Overall length of 2.0 inches compatible with standard gage handles

Compatibility

Designed for go inspection use and for setting micrometers, verniers, and other measuring devices requiring a 0.687 inch reference diameter. Fits standard plug gage handles sized for the 0.687 inch diameter range.

Installation Notes

Plug gages are handled and used by machinists, toolroom inspectors, and quality control technicians. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Never force the gage into a feature; entry should be smooth and free of binding. Store in a protective case away from temperature extremes to maintain dimensional integrity and traceability.
