Vermont Gage 112213280 Class Zz Minus Plug Pin Gage 13.28mm

Product Description

The VERMONT GAGE 112213280 is a Class ZZ Minus plug pin gage machined to a 13.28 mm diameter with a tolerance of 0.00508 mm. It is used to verify bore dimensions in precision machining and quality control environments. The gage is manufactured from steel with a 10 micro finish and measures 2 inches in overall length. Each unit ships with a Certificate of Accuracy with NIST traceability, making it suitable for documented inspection processes. Machinists, quality technicians, and metrology lab personnel are the primary users of this tool.

This plug pin gage is applied in NoGo inspection workflows where a bore or hole must be confirmed as within tolerance. It is also compatible with setup and verification tasks involving set micrometers, verniers, and other measuring devices. The Class ZZ designation indicates a minus tolerance configuration, meaning the gage is ground to the lower end of the tolerance band, which is standard practice for NoGo members in go/no-go gage sets. This part is suited for precision manufacturing, tool rooms, and quality assurance departments handling close-tolerance components.

Key Features

• Class ZZ Minus tolerance ground to 0.00508 mm for NoGo inspection applications
• 13.28 mm measurement diameter for precise bore verification
• Steel construction with 10 micro surface finish for durability and dimensional stability
• 2 inch overall length for standard hand-held use
• Includes Certificate of Accuracy with NIST traceability for documented quality programs

Compatibility

Designed for use in NoGo bore inspection and as a reference standard with set micrometers, verniers, and other calibrated measuring devices requiring a 13.28 mm reference diameter.

Installation Notes

This gage is a hand-held precision measuring tool and does not require mechanical installation. Handle with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Store in the provided case or a protective sleeve when not in use to preserve the surface finish and dimensional integrity. Verify the gage against its NIST-traceable certificate before introducing it into a calibration or inspection program.
