Vermont Gage 112114420 Class Zz Plus Plug Gage 14.42mm

Product Description

The VERMONT GAGE 112114420 is a Class ZZ Plus plug gage used to verify bore and hole dimensions to tight tolerances in precision measurement applications. Manufactured from tool steel with a 10 micro finish, this plug gage holds a tolerance of 0.00508 mm, making it suitable for go inspection tasks where dimensional accuracy is critical. The overall length is 2.0000 inches, and the nominal diameter is 14.42 mm. Each unit ships with a Certificate of Accuracy with NIST Traceability, supporting documented quality control workflows. Machinists, quality technicians, and metrology lab professionals are the primary users of this tool.

This plug gage is designed for go inspection use in manufacturing, machine shops, and quality assurance environments. It is compatible with standard gage handle systems and is used alongside set micrometers, verniers, and other calibrated measuring devices to confirm that bored or drilled features fall within specified dimensional limits. The 14.42 mm diameter targets precision-machined components where hole acceptance criteria must be verified per ASME B89.1 standards. Typical applications include incoming inspection, in-process checking, and final part acceptance on production floors.

Compatibility

Designed as an OEM-style replacement and standard fitting for use with conventional plug gage handle sets in go inspection applications per ASME B89.1.

Installation Notes

Plug gages are handled and used by quality technicians and machinists and do not require mechanical installation. Store the gage in its case when not in use to prevent surface damage and dimensional drift. Clean the gage and the bore being inspected before use to avoid measurement error from chips or debris. Do not force the gage into an undersized bore, as this can damage both the gage and the workpiece.
