Vermont Gage 112206480 Class Zz Minus Plug Pin Gage 6.48mm

Product Description

The VERMONT GAGE 112206480 is a Class ZZ Minus plug pin gage designed for NoGo inspection work in precision measurement applications. This single-ended pin gage measures 6.48 mm in diameter with a tolerance of 0.00508 mm, making it suited for verifying that bores and holes do not exceed their maximum allowable size. The overall length is 2 inches. Constructed from steel with a 10 microfinish surface coating, it delivers the dimensional consistency required for calibration-grade inspection. Each gage ships with a Certificate of Accuracy traceable to NIST standards, supporting documentation requirements in quality-controlled environments.

This pin gage is used in manufacturing, metrology labs, and machine shops where precise bore verification is required. It is appropriate for NoGo inspection routines and for setting or checking micrometers, vernier calipers, and other precision measuring devices. The 6.48 mm diameter fills a specific metric measurement need within a standard pin gage set. Technicians working to tight tolerances in aerospace, automotive, or general precision machining applications will find this gage fits standard inspection workflows.

Key Features

• Class ZZ Minus tolerance specification: 0.00508 mm for high-accuracy NoGo inspection
• Steel construction with 10 microfinish surface coating for dimensional stability and wear resistance
• 2-inch overall length for comfortable handling in standard bench and in-line inspection use
• NIST-traceable Certificate of Accuracy included for compliance and documentation purposes
• Designed for setting micrometers, verniers, and other calibrated measuring devices

Compatibility

Designed for use as a NoGo plug pin gage in metric bore inspection applications and for setting or referencing micrometers, vernier calipers, and comparable precision measuring instruments.

Installation Notes

Pin gages are handled and used by metrology technicians, quality inspectors, and machinists. Always clean the gage and the bore being checked before use to prevent debris from affecting measurement accuracy. Do not force the pin into a hole; Class ZZ gages are inspection tools, not assembly aids. Store in the provided case or a clean dry environment to protect the finish and dimensional integrity.
