It features a 90-degree flat head driven by a 5 mm hex socket and is fully threaded along its 16 mm overall length. Grade 12.9 indicates a high-strength fastener suited for demanding mechanical assemblies where precise clamping force and a flush or countersunk head profile are required. Machinists, maintenance technicians, and mechanical assemblers use this type of fastener when a standard cap screw head would protrude beyond a surface or interfere with mating components.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in metric mechanical assemblies across industrial, manufacturing, and maintenance applications. The fully threaded M8x1.25 shank makes it appropriate for through-hole and short-depth blind-hole installations. The black oxide finish provides mild corrosion resistance and reduces light reflection, which is common in tooling, fixtures, and machine component applications. It conforms to DIN 7991, a recognized international standard for countersunk socket screws, making it a direct fit wherever that standard is specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\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 profile seats flush in countersunk holes\u003c\/li\u003e\n  \u003cli\u003e5 mm hex socket drive for precise torque application with standard hex keys or socket tooling\u003c\/li\u003e\n  \u003cli\u003eFully threaded M8x1.25 shank along the entire 16 mm length\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion resistance and low-reflectance surface\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 7991 fastener standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in metric fastener applications requiring a DIN 7991 countersunk socket cap screw with an M8x1.25 thread and 16 mm overall length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists or mechanical technicians using a calibrated torque wrench and a 5 mm hex key or hex bit socket. Ensure the mating hole is properly countersunk to 90 degrees before seating the fastener. Do not exceed the rated torque for grade 12.9 M8 fasteners as specified by your engineering documentation or applicable standards. Verify thread engagement depth meets minimum requirements before applying final torque.\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: 16 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\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: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: DIN 7991\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 43155\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692192006450,"sku":"43155","price":23.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/828f3ce9dc6e0d4d07b05111a8bfdadc.jpg?v=1788294368","url":"https:\/\/voomisupply.com\/products\/value-collection-43155-flat-socket-cap-screw-m8x1-25","provider":"Voomi Supply","version":"1.0","type":"link"}
