Where calipers measure linear dimensions and protractors measure angles, radius gauges fill the gap of measuring curves — the inside of a fillet, the outside of a corner, the radius of a turned shoulder.

Imperial sets follow a similar pattern with 1\/64 inch and 1\/32 inch increments at the small end.

Store them flat in their case or roll, keep them clean and lightly oiled to prevent rust, and inspect for damage to the leaf edges before relying on the readings. A gauge with a chipped or bent leaf reads incorrectly; replace damaged leaves rather than continuing to use them. For traceable inspection workplaces, periodic calibration may be required as part of the broader measuring tool calibration regime.\u003c\/p\u003e\n\n\u003ch3\u003eCompanion ranges\u003c\/h3\u003e\n\u003cp\u003eRadius gauges sit alongside our broader measuring tools range — calipers, micrometers, height gauges, surface plates, dial indicators.
