Made from alloy steel with a black oxide coating, it carries a material grade of 12.9, indicating high tensile strength suited for demanding structural and mechanical fastening applications. The hex socket drive accepts a standard hex key for installation. This fastener is fully threaded along its length under head and conforms to ANSI B1.13M, ISO 4762, and ISO 898-1 standards. It is used across industrial, heavy equipment, and precision mechanical assemblies where high-strength metric fastening is required.\u003c\/p\u003e\n\u003cp\u003eThis screw is appropriate for use in industrial machinery, structural assemblies, tooling fixtures, and heavy-duty mechanical connections where a high-clamp-load metric fastener is specified. The M30 x 3.50 thread is a coarse-pitch metric thread common in large-diameter fastener applications. Grade 12.9 alloy steel construction makes this screw suitable for high-stress environments including hydraulic equipment, press assemblies, and machine frames. It is installed by maintenance technicians, millwrights, and mechanical assemblers working to metric fastener standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM30 x 3.50 coarse-pitch metric thread for large-diameter high-load applications\u003c\/li\u003e\n  \u003cli\u003e80 mm (approximately 3.15 inches) length under head, fully threaded\u003c\/li\u003e\n  \u003cli\u003eGrade 12.9 alloy steel construction for maximum tensile and proof load capacity\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduced light reflection\u003c\/li\u003e\n  \u003cli\u003eHex socket (internal hex) drive for high-torque installation with a hex key or socket tool\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI B1.13M, ISO 4762, and ISO 898-1 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style and aftermarket replacement hex socket cap screw for applications specifying an M30 x 3.50 fully threaded Grade 12.9 metric cap screw per ISO 4762 or ANSI B1.13M standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified millwrights, maintenance technicians, or mechanical assemblers familiar with metric fastener torque specifications for Grade 12.9 hardware. Always consult the equipment manufacturer or applicable engineering specifications for required torque values before installation. Ensure mating threads are clean and free of debris before driving the fastener. Use a properly sized hex key or hex socket to avoid rounding the drive recess.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M30 x 3.50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 80 mm (approximately 3.15 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 12.9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ANSI B1.13M, ISO 4762, ISO 898-1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: HOLO-KROME\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 76584\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51739477639474,"sku":"76584","price":69.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/08ab9b997f18c610bfec509098d16a95.jpg?v=1788815021","url":"https:\/\/voomisupply.com\/products\/holo-krome-76584-hex-socket-cap-screw-m30-x-3-50-80mm","provider":"Voomi Supply","version":"1.0","type":"link"}
