The screw features an M20 x 2.50 thread profile with a 300 mm length under head and is partially threaded, allowing it to bear shear loads across unthreaded shank sections. Manufactured from alloy steel to material grade 12.9, it delivers high tensile strength suitable for demanding load-bearing connections. A black oxide coating provides moderate corrosion resistance and reduces light reflection. Licensed contractors, millwrights, and mechanical assemblers are the typical installers for fasteners of this class.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for heavy-duty bolted connections in manufacturing equipment, hydraulic assemblies, machine frames, and structural fixtures where a high-clamp-load metric fastener is required. The hex socket drive accepts a standard Allen or hex key, making it ideal for installations where recessed-head clearance is needed and torque must be applied precisely. Partial threading keeps the unthreaded shank within the joint interface, which is standard practice for shear-loaded joints in industrial equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM20 x 2.50 metric thread with 300 mm length under head for deep-reach fastening\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank to handle shear loads and maintain joint alignment\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction at material grade 12.9 for maximum tensile and proof-load strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion protection and low-glare appearance\u003c\/li\u003e\n  \u003cli\u003eHex socket drive for high-torque input in tight or recessed clearance applications\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI B1.13M, 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 conforming to ISO 4762 and ANSI B1.13M, compatible with any M20 x 2.50 tapped hole or nut meeting the same metric thread standard in industrial and mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified millwright, maintenance technician, or mechanical assembler familiar with metric fastener torque requirements for grade 12.9 hardware. Always verify the tapped hole thread class and depth before driving the fastener. Use a calibrated torque wrench with the appropriate hex key bit to achieve the required clamp load without overdriving. De-energize and lock out any equipment before performing fastener replacement or assembly work on live machinery.\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: 300 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\u003eStandards\u003c\/strong\u003e: ANSI B1.13M, ISO 4762, ISO 898-1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.78 pounds\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: 760005440\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51787879383346,"sku":"760005440","price":95.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2816fc3ea1a0de3ebbded6c00312548_c2c346a8-4b74-4617-b816-027352d4e9c7.jpg?v=1789219649","url":"https:\/\/voomisupply.com\/products\/holo-krome-760005440-hex-socket-cap-screw-m20-x-2-50","provider":"Voomi Supply","version":"1.0","type":"link"}
