Vermont Gage 112314290 Class Zz Plus Plug Gage 14.29mm

Product Description

The VERMONT GAGE 112314290 is a Class ZZ Plus plug gage machined from tool steel and used to verify bore diameters to tight tolerances in precision inspection work. The gage measures 14.29 mm in diameter and holds a tolerance of 0.00508 mm, making it suitable for go inspection applications where dimensional accuracy is critical. Overall length is 2.0000 inches. A Certificate of Accuracy with NIST traceability is included, supporting documentation requirements in quality-controlled environments. Machinists, quality technicians, and metrology professionals install and use this gage on the shop floor and in inspection labs.

This plug gage is designed for go inspection use — confirming that a bored or reamed hole falls within the acceptable size range. It is also suited for setting micrometers, verniers, and other measuring devices requiring a known reference diameter. Typical applications include incoming inspection, in-process quality checks, and final acceptance inspection of machined components in manufacturing environments. The 10 micro surface finish on the gage surface supports consistent, repeatable contact with the workpiece.

Key Features

• Class ZZ Plus tolerance class: 0.00508 mm tolerance for precision go inspection
• Tool steel construction for wear resistance and long service life
• 10 micro surface coating and finish for consistent gage-to-bore contact
• Includes Certificate of Accuracy with NIST traceability for documented quality systems
• Conforms to ASME B89.1 standards for plain plug gages
• Overall length of 2.0000 inches for standard handle compatibility

Compatibility

Designed for use with standard plug gage handles and suitable for setting micrometers, verniers, and other measuring devices requiring a 14.29 mm reference diameter in go inspection applications.

Installation Notes

Plug gages should be handled with clean, dry hands or lint-free gloves to prevent surface contamination and corrosion from skin oils. Store the gage in its protective case when not in use to maintain surface finish and dimensional integrity. Before use, verify the gage is clean and free of burrs or debris; inspect the gage periodically and recertify according to your facility's calibration schedule. This gage is a precision measuring instrument — do not force it into a bore or use it as a cutting or prying tool.
