Built to DIN 7991 standard, it features an M8x1.25 thread and a 5.00 mm hex socket drive. The screw is fully threaded along its 30.00 mm overall length and manufactured from grade 12.9 alloy steel, providing high tensile strength suited to demanding mechanical assemblies. The metric blue finish offers a degree of corrosion resistance while serving as a visual identifier for metric-dimensioned fasteners. This fastener is installed by machinists, millwrights, and mechanical contractors working on precision assemblies.\u003c\/p\u003e\u003cp\u003eThis flat socket cap screw is used in applications where a standard hex socket cap head would protrude above the mating surface and interfere with adjacent components or movement. The 90-degree flat head seats flush into a countersunk hole, making it well suited for machine guards, frame assemblies, brackets, and fixtures where a smooth surface profile is required. Its fully threaded shank allows engagement along the entire length, which is advantageous in shallow or through-hole applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDIN 7991 standard flat socket cap screw for consistent dimensional accuracy\u003c\/li\u003e\n\u003cli\u003eGrade 12.9 alloy steel construction for high tensile and shear strength\u003c\/li\u003e\n\u003cli\u003eM8x1.25 metric thread with full threading along the 30.00 mm overall length\u003c\/li\u003e\n\u003cli\u003e5.00 mm hex socket drive for standard Allen key or hex bit installation\u003c\/li\u003e\n\u003cli\u003e90-degree flat head profile for flush, countersunk seating\u003c\/li\u003e\n\u003cli\u003eMetric blue finish for corrosion resistance and metric identification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DIN 7991 standard flat socket cap screw in M8x1.25 metric thread, compatible with countersunk holes machined to DIN 7991 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 5.00 mm hex key or hex socket bit. Countersink the mating hole to the appropriate 90-degree angle per DIN 7991 specifications before installation. Ensure the mating thread is clean and free of debris before driving. Grade 12.9 fasteners should not be substituted with lower-grade hardware in high-load or safety-critical joints without engineering review.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 30.00 mm (overall length)\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: 5.00 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\u003eThreading\u003c\/strong\u003e: Fully Threaded\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: Metric Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: DIN 7991\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: METRIC BLUE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: UST184059\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"METRIC BLUE","offers":[{"title":"Default Title","offer_id":67909770445106,"sku":"UST184059","price":1380.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ee2ad8fc51001baf98daab969736b17a_88851b72-db1c-48c9-aa6c-a2a55a7e0dc6.jpg?v=1791191926","url":"https:\/\/voomisupply.com\/products\/metric-blue-ust184059-flat-socket-cap-screw-m8x1-25","provider":"Voomi Supply","version":"1.0","type":"link"}
