Manufactured from 12.9 grade alloy steel with a black oxide finish, this screw delivers high tensile strength and moderate corrosion resistance. The 90-degree flat head seats into countersunk holes to sit flush with or below the mating surface. Drive engagement is achieved with a 3.00 mm hex socket. The M5x0.8 thread size with 40 mm overall length and partial threading configuration make it well suited for precision assemblies where thread engagement depth matters. Installed by machinists, maintenance technicians, and mechanical assemblers.\u003c\/p\u003e\u003cp\u003eThis flat socket cap screw is used in machine tool fixtures, precision mechanical assemblies, enclosures, and structural components where a flush head profile is critical. The black oxide finish reduces light reflection and provides a degree of surface protection in dry or lightly oiled environments. Partial threading is appropriate for applications requiring a smooth shank section to bear shear loads or to clamp materials of defined thickness. Conforms to DIN 7991 fastener standard.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e90-degree flat head profile for flush countersunk installation\u003c\/li\u003e\n\u003cli\u003e12.9 grade alloy steel for high tensile and proof load strength\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish for reduced reflectivity and light surface protection\u003c\/li\u003e\n\u003cli\u003e3.00 mm hex socket drive for positive torque engagement\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank per DIN 7991 standard\u003c\/li\u003e\n\u003cli\u003eMetric thread standard M5x0.8 for precise thread fit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DIN 7991 metric flat socket cap screw compatible with standard M5x0.8 countersunk hex socket applications in machine assemblies and fixtures.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a calibrated 3.00 mm hex key or socket driver. Countersink the mating material to a 90-degree included angle to achieve proper head seating. De-energize, depressurize, or lock out any equipment before fastener replacement or assembly work. Avoid over-torquing 12.9 grade fasteners without consulting applicable engineering torque specifications for the joint design.\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\u003eThreading\u003c\/strong\u003e: Partially 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\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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 43143\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723387207986,"sku":"43143","price":18.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/747bfafd92c3706102b0f1417b3e0a69.jpg?v=1788604297","url":"https:\/\/voomisupply.com\/products\/value-collection-43143-m5x0-8-flat-socket-cap-screw-12-9","provider":"Voomi Supply","version":"1.0","type":"link"}
