It measures 36 inches long, 3\/8 inch wide, and 3\/16 inch thick, and weighs 0.71 pounds. Pre hardened 4142 chromoly alloy steel offers a strong balance of toughness, fatigue resistance, and machinability, making this flat stock suitable for fabricating tooling components, jigs, fixtures, brackets, and wear parts. Machinists, tool and die makers, and maintenance technicians work with this material in shop and field applications where a ready-to-use hardened flat bar is required without additional heat treatment.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for light-duty tooling, machine components, and structural fabrication tasks where a compact cross-section and pre hardened condition reduce setup time. The 3\/16 inch thickness and 3\/8 inch width make it appropriate for narrow slots, keyways, shims, and small structural ties in industrial and maintenance environments. Sold in single-piece quantity with a minimum order quantity of one.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI\/SAE Type 4142 chromoly alloy steel with pre hardened condition for immediate use\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.250 inches ensures stock runs long, never short\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.005 inches for consistent fitment in close-tolerance applications\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus 0.001 inches supports precise layering and shimming work\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of 0.003 inches maintains cross-section geometry for accurate machining\u003c\/li\u003e\n\u003cli\u003eSingle-piece packaging with MOQ of one allows ordering exact quantities needed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI\/SAE Type 4142 pre hardened alloy steel flat stock suitable for general tooling, fixture, and machine component fabrication applications across industrial and maintenance trades.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, drilling, and grinding of pre hardened 4142 alloy steel requires carbide-tipped tooling and appropriate coolant to prevent work hardening and tool damage. Welding of pre hardened alloy steel should follow qualified preheat and post-weld heat treatment procedures per applicable shop standards. Always wear appropriate PPE including eye protection and gloves when cutting or grinding steel stock. Consult applicable OSHA and shop safety guidelines before machining.\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\u003eOverall Length\u003c\/strong\u003e: 36 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 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: 0.71 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: 81175499\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":52040373436722,"sku":"81175499","price":106.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_5a773fe8-25a5-4e4f-95a6-f5932ecf5538.jpg?v=1790026993","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-81175499-flat-stock-4142","provider":"Voomi Supply","version":"1.0","type":"link"}
