It features a 90-degree flat head with a hex socket drive and is manufactured from grade 10.9 alloy steel with a black oxide finish. The 10.9 material grade indicates high tensile strength, making this screw appropriate for joints that require controlled clamping force and resistance to loosening under vibration. Black oxide provides moderate corrosion resistance and reduces light reflection in finished assemblies. This fastener is installed using a standard hex key or Allen driver.\u003c\/p\u003e\u003cp\u003eThis screw is suited for use in metric-standard mechanical assemblies, industrial equipment, and structural fixtures where a low-profile countersunk head is required. The M6x1 thread size and 40mm overall length make it a common choice in general-purpose machine work, jig and fixture building, and equipment maintenance. The partial threading allows for a shank section that provides shear strength in close-tolerance bores. Sold individually, with a minimum order quantity of 25 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 10.9 alloy steel for high tensile strength and fatigue resistance\u003c\/li\u003e\n\u003cli\u003e90-degree flat head profile for flush countersunk installation\u003c\/li\u003e\n\u003cli\u003eHex socket drive accepts standard 4mm hex key\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish for moderate corrosion resistance and low reflectivity\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank for improved shear load performance\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 7991 fastener standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DIN 7991-compliant metric flat socket cap screw suitable for countersunk M6 threaded holes in metric-standard machinery, fixtures, and structural assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 4mm hex key or Allen driver torqued to the appropriate value for a grade 10.9 M6 fastener per the applicable assembly specification. Ensure the mating countersink is machined to 90 degrees to achieve full head contact. Do not install into non-metric or inch-standard threaded holes.
