It features a 90-degree flat head with a 3.00 mm hex socket drive and is manufactured from grade 12.9 alloy steel, giving it high tensile strength suited to demanding mechanical connections. The black oxide finish provides mild corrosion resistance and a low-reflectance appearance. With an M5x0.8 thread size and an overall length of 40.00 mm, this screw is partially threaded and carries a thread fit class of 4G. Licensed trades and industrial maintenance professionals install this fastener where a low-profile head is required to sit flush with a mating surface.\u003c\/p\u003e\u003cp\u003eThis flat socket cap screw is used in applications that demand a recessed, flush-mount fastener  -  common in machine tool assemblies, fixture plates, robotics frames, and mechanical enclosures. The 90-degree countersunk head mates with standard metric countersunk hole profiles. The hex socket drive accepts a 3.00 mm hex key, making it suitable for tight-clearance installations where a wrench cannot be used. Partially threaded shanks provide improved clamping force between joined parts. This screw is sold in packages of one unit with a minimum order quantity of 10 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 12.9 alloy steel construction for high tensile and proof load strength\u003c\/li\u003e\n\u003cli\u003e90-degree flat head seats flush in standard metric countersunk holes\u003c\/li\u003e\n\u003cli\u003e3.00 mm hex socket drive for use with a standard hex key in tight spaces\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish for mild corrosion resistance and low reflectance\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank for improved clamping between mating components\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI B1.13M and ISO 10642 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style metric flat socket cap screw conforming to ANSI B1.13M and ISO 10642, suitable for use in any application requiring an M5x0.8 countersunk hex socket fastener with a 40.00 mm overall length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by machinists, millwrights, or mechanical assemblers. Before installation, ensure the mating countersunk hole is drilled and chamfered to the correct 90-degree angle and diameter for an M5 flat socket screw. Use the correct 3.00 mm hex key to drive the fastener; an undersized or worn key risks rounding the socket. Grade 12.9 fasteners should not be reused in critical load-bearing joints once they have been torqued to specification on a prior installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M5x0.8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 40.00 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: 3.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 11.20 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 3.1000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially 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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 87078\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51739640594738,"sku":"87078","price":1008.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4e14fa2f3ded20955a633a001935bb0_75fdf969-c740-4a45-b530-6bc0abb420c3.jpg?v=1788817242","url":"https:\/\/voomisupply.com\/products\/holo-krome-87078-flat-socket-cap-screw-m5x0-8-40mm","provider":"Voomi Supply","version":"1.0","type":"link"}
