Manufactured from alloy steel to material grade 12.9, this screw delivers the elevated tensile and proof-load strength required in demanding structural and equipment installations. The black oxide finish provides mild corrosion resistance and reduces light reflection on exposed fasteners. With a thread size of M20 x 2.50 and a fully threaded shank measuring 65 mm under the head, this screw is driven with a standard hex socket tool. It meets ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 standards.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for mechanical assemblies, equipment mounting, and structural connections where high clamp load and precision thread engagement are critical. Fully threaded along the 65 mm length under head, it is appropriate for through-bolt configurations and short-grip fastening scenarios. Typical installers include millwrights, pipefitters, mechanical contractors, and maintenance technicians working with industrial machinery, HVAC equipment frames, pump assemblies, and structural steel components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlloy steel construction rated to material grade 12.9 for high tensile strength\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank at M20 x 2.50 thread pitch over 65 mm length under head\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating for mild corrosion resistance and surface protection\u003c\/li\u003e\n  \u003cli\u003eHex socket drive for positive torque engagement with standard allen-key tooling\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI B1.13M, DIN 912, 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 a standard DIN 912 and ISO 4762 metric hex socket cap screw suitable for any M20 x 2.50 threaded application requiring a grade 12.9 alloy steel fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or tradesperson familiar with metric fastener torque requirements for grade 12.9 hardware. Always verify thread engagement depth and mating material before assembly. Use a calibrated torque wrench sized for M20 fasteners to achieve proper clamp load without yielding the fastener. Inspect threads in the receiving component for damage or contamination before installation.\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: 65 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 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: 0.555 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: 76504\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51732790444338,"sku":"76504","price":17.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2816fc3ea1a0de3ebbded6c00312548_bc7ce498-4aab-4cd2-a6f8-8218e79d0567.jpg?v=1788746843","url":"https:\/\/voomisupply.com\/products\/holo-krome-76504-hex-socket-cap-screw-m20-x-2-50-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
