It measures 36 inches long by 1 inch wide by 1 inch thick and ships in a single-piece quantity. The 4142 chromium-molybdenum alloy grade delivers a balance of toughness, wear resistance, and through-hardened strength that makes it well suited for tooling, fixturing, and structural machine components. Machinists, tool-and-die makers, and maintenance professionals working in fabrication shops rely on this flat stock for applications that demand dimensional consistency and material integrity straight from the bar.\u003c\/p\u003e\u003cp\u003eThis flat stock is used in general industrial and manufacturing environments where a pre-hardened condition eliminates additional heat-treat steps. Typical applications include die blocks, wear plates, guide rails, jigs, fixtures, and structural machine components. Because the bar arrives pre-hardened, it is ready for machining to final dimensions without an intermediate hardening cycle, reducing lead time in tooling and repair work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI\/SAE Type 4142 chromium-molybdenum alloy steel for high toughness and wear resistance\u003c\/li\u003e\n\u003cli\u003ePre-hardened condition  -  no additional heat treatment required before use\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.250 inches ensures consistent stock length for cut-to-size work\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.005 inches supports accurate layout and machining\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus 0.001 inches for close-tolerance tooling applications\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of 0.003 inches maintains perpendicularity across the bar profile\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-use flat bar for general machining, tooling, and fabrication applications requiring AISI\/SAE 4142 pre-hardened alloy steel stock.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and machining of pre-hardened 4142 alloy steel requires carbide tooling; high-speed steel tooling is generally not recommended at full hardness. Secure the workpiece firmly in a vise or fixture before cutting or grinding operations. Wear appropriate PPE including eye protection and gloves when handling machined edges. Consult applicable shop safety standards and equipment manufacturer guidelines before beginning any machining operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Specification\u003c\/strong\u003e: AISI\/SAE Type 4142 Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCondition\u003c\/strong\u003e: Pre-Hardened\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 36 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Thickness\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: plus 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness Tolerance\u003c\/strong\u003e: plus 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Tolerance\u003c\/strong\u003e: 0.003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 10.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31231200\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DRILL ROD TOOL STEELS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 81177008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":67951526510898,"sku":"81177008","price":236.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_bf85f24c-c559-4b36-a9c8-f082ee81c26b.jpg?v=1791728940","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-81177008-4142-flat-stock-36x1x1","provider":"Voomi Supply","version":"1.0","type":"link"}
