Setting Ring Gauge

A setting ring is a precision-machined cylindrical gauge used for calibrating measurement instruments such as bore gauges, micrometers, and dial indicators. Typically made from hardened tool steel or carbide, it features a lapped internal diameter with known tolerance. Setting rings provide a master reference for zero-point adjustment, ensuring accurate and repeatable measurements in quality control and manufacturing environments. Common applications include automotive parts inspection, bearing fitting, and CNC machine setup. Proper handling and periodic recertification maintain their calibration standard integrity.
