The 90-degree flat head seats flush with or below the mating surface when countersunk, eliminating protrusion in tight clearance assemblies. Manufactured from grade 12.9 alloy steel with a black oxide finish, this screw delivers high tensile strength and moderate corrosion resistance. The M8x1.25 thread is fully threaded along the 30 mm overall length. Drive engagement is through a 5 mm hex socket, requiring a matching Allen key or hex bit driver. Installers in mechanical, HVAC bracket, and equipment assembly work rely on this grade for high-load fastening.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in metal-to-metal fastening where a flush or countersunk head profile is required. Typical applications include machine frames, HVAC equipment panels, electrical enclosures, pump housings, and structural brackets. The 12.9 material grade meets the demands of high-stress mechanical assemblies. This screw conforms to DIN 7991, making it a direct fit where that fastener standard is specified. Sold individually with a minimum order quantity of 25 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree flat head seats flush in countersunk holes for a low-profile finish\u003c\/li\u003e\n  \u003cli\u003eGrade 12.9 alloy steel provides high tensile and proof-load strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish offers moderate corrosion protection and reduces light reflection\u003c\/li\u003e\n  \u003cli\u003eFully threaded M8x1.25 shaft along full 30 mm overall length\u003c\/li\u003e\n  \u003cli\u003e5 mm hex socket drive for standard Allen key or hex bit installation\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 7991 fastener standard for metric flat socket cap screws\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 7991-compliant metric flat socket cap screw for use in any M8x1.25 countersunk threaded application requiring a grade 12.9 fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 5 mm hex key or hex socket bit driver. Ensure the receiving hole is properly countersunk to 90 degrees to achieve full head seating and correct clamp load. Follow equipment manufacturer torque specifications for grade 12.9 M8 fasteners as outlined in applicable mechanical codes. Inspect threads in the mating material for damage before installation to prevent galling or cross-threading.\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: 30 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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 25\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: 43158\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692898976050,"sku":"43158","price":19.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c8758c0d4dc415dc4b7546687e9e99fb.jpg?v=1788304684","url":"https:\/\/voomisupply.com\/products\/value-collection-43158-m8x1-25-flat-socket-cap-screw-12-9","provider":"Voomi Supply","version":"1.0","type":"link"}
