Vermont Gage 111181400 Class Zz Plus Plug Gage 0.814 in

Product Description

The VERMONT GAGE 111181400 is a Class ZZ Plus plug gage used to verify hole diameters to a tight dimensional tolerance. Manufactured from tool steel, this gage holds a tolerance of 0.0002 inches and delivers a 10 microinch surface finish. It is a go-type inspection tool used to confirm that a bored, drilled, or reamed hole falls within the acceptable dimensional range. The 111181400 conforms to ASME B89.1 standards and ships with a Certificate of Accuracy with NIST traceability, making it suitable for applications that require documented calibration. Machinists, quality technicians, and tool-room inspectors rely on this type of gage as part of standard go/no-go inspection routines.

This plug gage is designed for go inspection of holes measuring 0.814 inches in diameter. It is also suited for setting and verifying micrometers, verniers, and other measuring devices. Typical applications include incoming inspection, in-process quality checks, and final inspection in machine shops, fabrication facilities, and manufacturing environments. The overall length of 2.0 inches suits standard hand-held use with no additional tooling required.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for precise go-type inspection
• 10 microinch surface finish for consistent, repeatable contact
• Tool steel construction for durability and wear resistance
• Conforms to ASME B89.1 dimensional standards
• Includes Certificate of Accuracy with NIST traceability
• Suitable for setting micrometers, verniers, and other measuring devices

Compatibility

Designed for go inspection of 0.814-inch diameter holes and for use with micrometers, verniers, and other measuring devices requiring a traceable reference standard.

Installation Notes

Plug gages are handled and used by quality technicians and machinists in inspection environments. Keep the gage clean and lightly oiled when not in use to prevent corrosion and surface damage. Do not force the gage into an undersized hole, as this can damage both the gage and the workpiece. Store in the provided case or a protected location away from other tools to preserve the calibrated surface finish.
