Manufactured from alloy steel with a Material Grade 12.9 rating, it delivers exceptional tensile and yield strength suited for demanding industrial and trade use. The screw features a black oxide coating that provides mild corrosion resistance and a clean, low-reflectance finish. The 90 mm length under head accommodates thick assemblies and flanged joints where positive clamping force is critical. Installation requires a hex socket driver or Allen key of the appropriate metric size. This fastener meets ANSI B1.13M, ISO 4762, and ISO 898-1 standards.\u003c\/p\u003e\n\u003cp\u003eThe HOLO-KROME 76585 is used across industrial machinery, heavy equipment assembly, structural steel fabrication, and mechanical systems requiring high-strength metric fasteners. The M30 thread size places this fastener in heavy-duty service categories typical of commercial and industrial installations rather than light residential work. Maintenance technicians, millwrights, pipefitters, and heavy equipment mechanics frequently specify Grade 12.9 alloy steel socket cap screws for critical joint applications where standard hardware-grade fasteners would be inadequate.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM30 x 3.50 metric thread  -  heavy-duty size for high-load structural and mechanical joints\u003c\/li\u003e\n  \u003cli\u003e90 mm length under head  -  accommodates thick flanges and deep-stack assemblies\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank for maximum thread engagement along the entire fastener length\u003c\/li\u003e\n  \u003cli\u003eGrade 12.9 alloy steel construction  -  among the highest standard strength grades for metric fasteners\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion resistance and reduced surface reflectance\u003c\/li\u003e\n  \u003cli\u003eMeets 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 M30 x 3.50 metric threaded applications conforming to ISO 4762 socket head cap screw geometry and ISO 898-1 mechanical property requirements.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a properly sized metric hex socket key or driver rated for Grade 12.9 fastener torque loads  -  use calibrated torque tooling appropriate to the joint specification. Always degrease or treat mating surfaces per the assembly specification before installation. De-energize or lock out any equipment before servicing fastened assemblies in electrical or mechanical systems. Do not substitute a lower-grade fastener in any joint originally 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: M30 x 3.50 Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 90 mm\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 Coating\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\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: 76585\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51740672229682,"sku":"76585","price":75.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2816fc3ea1a0de3ebbded6c00312548_8673d67f-d273-49b6-93ff-e5f898c872a1.jpg?v=1788826623","url":"https:\/\/voomisupply.com\/products\/holo-krome-76585-hex-socket-cap-screw-m30-x-3-50-metric","provider":"Voomi Supply","version":"1.0","type":"link"}
