Vermont Gage 111186200 Class Zz Plus Plug Gage 0.862 in

Product Description

The VERMONT GAGE 111186200 is a Class ZZ Plus plug gage used to verify bore and hole diameters in precision inspection work. It measures a nominal diameter of 0.862 inches with a tolerance of 0.0002 inches, making it well-suited for high-accuracy go inspection tasks. The gage is machined from tool steel and carries a 10 microinch surface finish. It comes with a Certificate of Accuracy with NIST traceability, supporting documented quality control processes. Metrology technicians, machinists, and quality control inspectors use this type of gage in production and inspection environments where tight dimensional verification is required.

This plug gage is intended for go inspection of machined holes, bores, and features requiring close dimensional control. It is also used to set and verify micrometers, verniers, and other measuring devices. The 0.862-inch diameter makes it a direct-use reference standard in shops and inspection labs handling precision turned, bored, or reamed components. At 2.0 inches overall length, it fits standard gage handle setups used in bench and in-process inspection routines. Conformance to ASME B89.1 ensures the gage meets recognized dimensional metrology standards.

Key Features

• 0.862-inch nominal measurement diameter for direct go inspection use
• 0.0002-inch tolerance for high-accuracy dimensional verification
• 10 microinch surface finish for consistent, repeatable gage contact
• Tool steel construction for durability and wear resistance in production environments
• Includes Certificate of Accuracy with NIST traceability for documented quality control
• Meets ASME B89.1 dimensional metrology standards

Compatibility

Designed for use as a go inspection gage and as a setting standard for micrometers, verniers, and other measuring devices requiring a 0.862-inch diameter reference.

Installation Notes

Plug gages are handled and used by metrology technicians and machinists trained in precision measurement practices. Store the gage in its case when not in use and keep it clean and lightly oiled to prevent corrosion of the tool steel. Do not force the gage into an undersized bore, as this can damage both the gage and the workpiece. Allow the gage and workpiece to stabilize to the same ambient temperature before inspection to avoid thermal expansion errors.
