Manufactured from alloy steel to material grade 12.9, this screw delivers exceptional tensile strength and is finished with a black oxide coating for moderate corrosion resistance. The M24 x 3.00 thread size paired with a 200 mm length under head makes it well-suited for heavy-duty bolted connections where precision and clamping force are critical. It is partially threaded, conforming to ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 standards. Installation is performed with a hex socket drive tool.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in demanding mechanical, structural, and industrial assembly applications requiring grade 12.9 alloy steel fasteners. Typical install scenarios include machine bases, heavy equipment frames, die sets, fixtures, and other assemblies where high preload and reliable clamping are required. The black oxide finish is suited for interior or protected environments where light rust inhibition is acceptable. Machinists, millwrights, and industrial maintenance technicians are the primary installers of this fastener size and grade.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 12.9 alloy steel construction for maximum tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides light corrosion resistance and reduces light glare on exposed hardware\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows for precise shear-load transfer in bolted joints\u003c\/li\u003e\n  \u003cli\u003eHex socket drive type for high-torque installation in confined or recessed spaces\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 standards for metric fastener compliance\u003c\/li\u003e\n  \u003cli\u003eM24 x 3.00 thread pitch conforms to standard metric coarse thread series\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard DIN 912 and ISO 4762 metric socket cap screw suitable for any M24 x 3.00 tapped hole application requiring a grade 12.9 partially threaded fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a properly sized hex socket key or socket drive tool matched to the M24 cap screw drive. De-energize and lock out any machinery before fastener installation or removal per OSHA lockout-tagout requirements. Apply thread lubricant or fastener-grade anti-seize as appropriate for the joint design before torquing to the engineer-specified value. Do not substitute a lower-grade fastener in any joint designed for grade 12.9 hardware.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M24 x 3.00\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 200 mm (approximately 7.87 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially 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 Coating\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standards\u003c\/strong\u003e: ANSI B1.13M, DIN 912, ISO 4762, ISO 898-1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.975 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: HOLO-KROME\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 76579\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51739532755250,"sku":"76579","price":60.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2816fc3ea1a0de3ebbded6c00312548_77858476-03cd-4a5a-a480-801709100d5d.jpg?v=1788815824","url":"https:\/\/voomisupply.com\/products\/holo-krome-76579-hex-socket-cap-screw-m24-x-3-00-200mm","provider":"Voomi Supply","version":"1.0","type":"link"}
