Vermont Gage 111166500 Class Zz Plus Plug Gage 0.665 in

Product Description

The VERMONT GAGE 111166500 is a Class ZZ Plus plug gage manufactured from tool steel for dimensional inspection of bores, holes, and openings at 0.665 inches diameter. Holding a tolerance of 0.0002 inches and a surface finish of 10 microinch Ra, this gage delivers the accuracy required for Go inspection applications in precision measurement workflows. The 2.0-inch overall length provides a practical handling profile for bench or floor inspection use. A Certificate of Accuracy with NIST traceability is included, meeting documentation requirements for quality management systems. Machinists, quality technicians, and metrology staff are the primary users of this tool.

This plug gage is suited for Go inspection tasks on machined parts, castings, and fabricated components where hole diameter must be verified to tight tolerances. It is also used for setting and verifying micrometers, vernier calipers, and other comparative measuring devices. Typical environments include machine shops, inspection departments, and manufacturing facilities operating under ASME B89.1 dimensional standards. The 0.665-inch diameter makes it applicable to a range of standard bore and hole sizes found in general industrial and precision machining work.

Key Features

• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 dimensional gage standards
• 2.0-inch overall length for practical handling at the bench or inspection station

Compatibility

Designed for Go inspection of bores and holes at 0.665 inches diameter, and for use as a setting master with micrometers, verniers, and other measuring devices per the stated application data.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no installation in the traditional sense applies. Store the gage in its case when not in use to prevent nicks or corrosion that would compromise accuracy. Clean the gage and the workpiece bore before inspection to remove chips, oil, or debris. Do not force the gage into an undersized hole, as this can damage both the gage and the part surface.
