Manufactured from 12.9 grade alloy steel with a black oxide finish, this screw delivers high tensile strength and moderate corrosion resistance in a compact, low-profile head. It features an M8x1.25 thread and measures 40 mm in overall length, fully threaded from head to tip. The 90-degree flat head seats cleanly into countersunk holes, making it a dependable choice where a protruding head would interfere with mating surfaces or moving components.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for precision mechanical assemblies, tooling fixtures, machine bases, and industrial equipment where high clamping force and a flush finish are required. The hex socket drive accepts a 5 mm hex key, allowing high torque application in tight clearances. Both manufacturing and maintenance technicians working on metalworking equipment, automation systems, and structural machine components regularly specify this type of fastener.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e12.9 grade alloy steel construction for high tensile and proof load capacity\u003c\/li\u003e\n  \u003cli\u003e90-degree flat head profile seats flush in standard countersunk holes\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides a uniform matte appearance with light corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eFully threaded along the entire 40 mm length for maximum engagement in thin or shallow materials\u003c\/li\u003e\n  \u003cli\u003e5 mm hex socket drive compatible with standard hex keys and hex-bit drivers\u003c\/li\u003e\n  \u003cli\u003eConforms to 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 metric flat socket cap screw for use in standard M8x1.25 countersunk holes conforming to ISO 10642 and ANSI B1.13M specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a 5 mm hex key or hex-bit driver. Ensure the mating countersink angle is machined to 90 degrees to achieve full head seating and proper load distribution. Verify hole depth and thread engagement before final torquing. De-grease mating surfaces and inspect thread fit class 4G compatibility before assembly.\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\u003eOverall Length\u003c\/strong\u003e: 40 mm\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 decimal equivalent (metric-spec part)\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\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: 87144\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51741984063794,"sku":"87144","price":9173.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4e14fa2f3ded20955a633a001935bb0_470ce43f-88f6-4118-8fdb-615af03e699e.jpg?v=1788834730","url":"https:\/\/voomisupply.com\/products\/holo-krome-87144-flat-socket-cap-screw-m8x1-25-40mm","provider":"Voomi Supply","version":"1.0","type":"link"}
