Built from stainless steel with a satin chrome finish, it measures a fixed radius of 5\/16 inch (0.31 inches maximum radius). Each leaf is double-ended, providing one convex profile and one concave profile for checking inside and outside radii with a single tool. Machinists, tool-and-die workers, and quality control technicians use radius gages to confirm fillet and corner radii against print specifications during inspection or in-process fitting. The part weighs 0.05 pounds.\u003c\/p\u003e\n\u003cp\u003eThis radius gage is suited for use in machine shops, fabrication environments, and maintenance facilities where dimensional verification of curved surfaces is required. It is typically used alongside surface plates, vises, or directly on the workpiece to confirm that a machined or ground radius matches the design specification. The single-leaf format is practical when only one specific radius size is needed on the job, reducing clutter in a toolbox or gage kit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasures a fixed radius of 5\/16 inch (0.31 inches) for consistent, repeatable inspection\u003c\/li\u003e\n  \u003cli\u003eDouble-ended leaf provides both convex and concave radius profiles per gage\u003c\/li\u003e\n  \u003cli\u003eStainless steel construction resists corrosion and wear in shop environments\u003c\/li\u003e\n  \u003cli\u003eSatin chrome finish reduces glare during visual fit checks\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.05 pounds, easy to carry in a tool pouch or gage roll\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard single-leaf radius gage for general dimensional inspection of convex and concave radii on machined, cast, or fabricated workpieces where a 5\/16 inch radius specification applies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eRadius gages are inspection tools and do not require permanent installation. Clean the contact surface of the gage and the workpiece before use to ensure accurate fit. Hold the gage leaf firmly against the radius being checked and view the fit against a light source to identify gaps. Store the gage in a protective case or roll when not in use to prevent damage to the profiled edges.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRadius\u003c\/strong\u003e: 5\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Radius\u003c\/strong\u003e: 0.31 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Configuration\u003c\/strong\u003e: Convex and Concave Radii per Each Leaf\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Satin Chrome\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 50639\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540177092914,"sku":"50639","price":21.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d1b95e6e9bec176360bde0a8ed105f16.jpg?v=1785848068","url":"https:\/\/voomisupply.com\/products\/starrett-50639-radius-gage-5-16-inch-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
