Built from 12.9 grade alloy steel with a black oxide finish, this screw delivers corrosion resistance and a clean appearance in demanding assemblies. The 90-degree flat head seats fully into a countersunk hole, eliminating protrusion above the mating surface. Drive engagement is through a 5 mm hex socket. Thread size is M8x1.25 with full threading along the 45 mm overall length. Licensed trades and industrial maintenance technicians specify this grade for structural and high-stress fastening work.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for precision mechanical assemblies, industrial equipment, tooling fixtures, and structural connections where a countersunk profile is required. The 12.9 material grade makes it appropriate for high-load applications in both light manufacturing and heavy-duty machinery. It meets ANSI B1.13M and ISO 10642 standards, making it a direct fit in metric engineering designs that call for those specifications. Fully threaded construction allows maximum thread engagement across the full screw length, which is important in thin-material or through-bolt applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e12.9 alloy steel construction for high tensile and proof load ratings\u003c\/li\u003e\n  \u003cli\u003e90-degree flat head profile seats flush in countersunk holes\u003c\/li\u003e\n  \u003cli\u003e5 mm hex socket drive for standard allen key or bit engagement\u003c\/li\u003e\n  \u003cli\u003eFull threading along the 45 mm length maximizes thread engagement\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and low-glare appearance\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI B1.13M and ISO 10642 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 metric flat socket cap screw for assemblies specifying M8x1.25 thread, 90-degree countersunk head geometry, and ISO 10642 or ANSI B1.13M compliance.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by millwrights, maintenance technicians, or mechanical assemblers using a calibrated hex key or socket bit sized to 5 mm. Ensure the mating countersink is machined to the correct 90-degree angle and diameter to seat the head fully before torquing. Use a calibrated torque tool appropriate for 12.9 grade M8 fasteners and follow the assembly engineering specifications for the applicable joint. Avoid reusing fasteners removed from high-stress applications, as cyclic loading can reduce clamp load reliability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M8x1.25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 45 mm overall\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: 90 degree Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 17.92 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 4.96 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Fit Class\u003c\/strong\u003e: 4G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric\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\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ANSI B1.13M, ISO 10642\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\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: 87143\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51743325716786,"sku":"87143","price":1936.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4e14fa2f3ded20955a633a001935bb0_31e7af74-867e-4141-8622-ce937d8df750.jpg?v=1788845656","url":"https:\/\/voomisupply.com\/products\/holo-krome-87143-flat-socket-cap-screw-m8x1-25-45mm","provider":"Voomi Supply","version":"1.0","type":"link"}
