Measuring 24 inches in length, 1.5 inches wide, and 0.5 inches thick, it is a precision-tolerance raw stock bar suited for fabrication, machining, and layout work. Thickness tolerance is held to plus or minus 0.001 inches, width tolerance to plus 0.000 to 0.005 inches, and length tolerance to plus 0.625 inches. Machinists, toolmakers, and fabricators working in shops, trades, and industrial settings rely on AISI C1018 flat stock for its consistent chemistry, predictable machinability, and weldability without the brittleness of higher-carbon grades.\u003c\/p\u003e\n\u003cp\u003eThis flat stock bar is used in general fabrication, repair, and prototype work across mechanical, HVAC, plumbing, and industrial trades. Typical applications include making brackets, supports, straps, shims, and custom hardware where close dimensional tolerances are required. The C1018 low carbon chemistry makes the bar well-suited for bending, drilling, tapping, and light welding. It is appropriate for both shop fabrication environments and field-service applications where a reliable, machinable steel bar stock is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAISI Type C1018 low carbon steel chemistry for consistent machinability and weldability\u003c\/li\u003e\n  \u003cli\u003eThickness tolerance held to plus or minus 0.001 inches for precision fitment\u003c\/li\u003e\n  \u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches for controlled fit in close-tolerance applications\u003c\/li\u003e\n  \u003cli\u003e24-inch length with a plus 0.625-inch length tolerance, allowing for cut-to-size flexibility\u003c\/li\u003e\n  \u003cli\u003eFlat bar profile suitable for brackets, straps, shims, and structural supports\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity with no minimum order beyond one unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose AISI C1018 low carbon steel flat stock bar for use in fabrication, machining, and repair applications across mechanical and industrial trades.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCutting, drilling, and shaping should be performed by qualified machinists or tradespeople using appropriate metal-working tools and personal protective equipment. Deburr all cut edges before handling or installation to reduce injury risk and ensure proper fit. When welding C1018 bar stock, follow applicable AWS standards and ensure proper ventilation. Store flat stock horizontally on a flat surface to prevent warping or bowing prior to use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Specification\u003c\/strong\u003e: AISI Type C1018 Low Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 24 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Thickness\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: plus 0.000 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness Tolerance\u003c\/strong\u003e: plus or minus 0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Tolerance\u003c\/strong\u003e: plus or minus 0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31231200\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 54987\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542026846514,"sku":"54987","price":181.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d5ffb3ae28a26f46e95460f2f70f3a2_e8d6a155-72b6-4c50-bf16-0e076937154d.jpg?v=1785890031","url":"https:\/\/voomisupply.com\/products\/starrett-54987-low-carbon-steel-flat-stock-aisi-c1018","provider":"Voomi Supply","version":"1.0","type":"link"}
