It features an M20 x 2.50 thread size with a 130 mm length under head, partial threading, and a hexagonal socket drive. The fastener is manufactured from alloy steel to material grade 12.9, the highest common grade for socket cap screws, indicating exceptional tensile and yield strength. A black oxide coating provides moderate corrosion resistance and a uniform matte finish. This screw is installed using a hex key or Allen driver and is commonly specified by millwrights, maintenance technicians, and mechanical contractors.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for heavy-duty mechanical assemblies, machine frames, tooling fixtures, and structural joints requiring a high-clamp-load fastener. The partial threading allows the unthreaded shank to function as a precise locating feature, reducing shear load on the threads. It conforms to ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 standards, making it appropriate for metric-specified engineering drawings in both OEM manufacturing and MRO replacement contexts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM20 x 2.50 thread size with 130 mm length under head\u003c\/li\u003e\n  \u003cli\u003eMaterial grade 12.9 alloy steel for maximum tensile strength\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for precise location and shear resistance\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating for corrosion resistance and low-reflectance finish\u003c\/li\u003e\n  \u003cli\u003eHex socket drive compatible with standard Allen keys and hex bit drivers\u003c\/li\u003e\n  \u003cli\u003eCompliant with ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard metric hex socket cap screw per DIN 912 and ISO 4762, suitable for any M20 x 2.50 tapped hole application requiring a grade 12.9 high-strength fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by millwrights or mechanical technicians using a properly sized hex key or driven hex bit. Always verify the mating tapped hole meets the M20 x 2.50 metric thread specification and confirm the hole depth accommodates the partially threaded shank before assembly. De-energize and lockout any equipment before fastener replacement on live machinery per applicable safety codes. Do not substitute a lower material grade fastener in applications specifying 12.9.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M20 x 2.50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 130 mm\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 Standard\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 pound\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: 76536\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51739419509042,"sku":"76536","price":47.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2816fc3ea1a0de3ebbded6c00312548_baa532fc-4a0f-4dce-b52d-56cc9f9f402c.jpg?v=1788814398","url":"https:\/\/voomisupply.com\/products\/holo-krome-76536-hex-socket-cap-screw-m20-x-2-50-metric","provider":"Voomi Supply","version":"1.0","type":"link"}
