Manufactured from 12.9-grade alloy steel with a black oxide finish, this screw delivers high tensile strength and basic corrosion resistance in a compact form factor. It features a 90-degree flat head driven by a 5 mm hex socket and is fully threaded along its 20 mm overall length with an M8x1.25 thread pitch. It is suited for precision mechanical assemblies, tooling fixtures, and structural joints where head protrusion must be minimized. Licensed tradespeople and experienced assemblers install this type of fastener in both industrial and field settings.\u003c\/p\u003e\u003cp\u003eThis flat socket cap screw is commonly used in mechanical, structural, and manufacturing applications where a countersunk, flush-mounted fastener is needed. The M8x1.25 metric thread and 12.9 material grade make it appropriate for high-load joints in machinery, automotive components, and fabricated metal assemblies. The black oxide finish provides a clean appearance and mild surface protection. This screw conforms to DIN 7991 fastener standards and uses metric thread standards throughout.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e12.9-grade alloy steel construction for high tensile and proof load capacity\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish for a clean appearance and mild corrosion resistance\u003c\/li\u003e\n\u003cli\u003e90-degree flat head profile for flush or countersunk installation\u003c\/li\u003e\n\u003cli\u003e5 mm hex socket drive for precise torque application\u003c\/li\u003e\n\u003cli\u003eFully threaded along entire 20 mm length for maximum thread engagement\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 7991 fastener standard with metric thread standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style metric flat socket cap screw for use in countersunk M8 threaded holes conforming to DIN 7991 specifications in industrial, mechanical, and structural assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using a 5 mm hex key or hex socket driver rated for high-strength fasteners.
