It features a 90-degree flat head driven by a 3 mm hex socket, and is manufactured from 316 austenitic stainless steel to Grade A4 specification. The M5x0.8 thread pitch and 20 mm overall length make this screw a standard choice in metric assemblies. Partial threading provides full thread engagement in the fastened material while allowing clearance in the through-hole portion. Plumbers, HVAC technicians, electricians, and general trade professionals reach for Grade A4 stainless fasteners where corrosion resistance is a priority.\u003c\/p\u003e\u003cp\u003eThis screw is suited for metric assemblies in corrosive or wet environments, including marine, chemical, and outdoor installations. The 316 stainless steel composition provides superior resistance to chloride-bearing environments compared to 304-grade fasteners. Packaged in quantities of 25 per pack with a minimum order of one pack, the A410391 is appropriate for both maintenance stock and project-specific purchasing. Applications include equipment panels, pipe supports, enclosures, and mechanical assemblies where a flush-mount fastener is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e90-degree flat head for flush or countersunk seating\u003c\/li\u003e\n\u003cli\u003e3 mm hex socket drive compatible with standard metric Allen keys and bits\u003c\/li\u003e\n\u003cli\u003eM5x0.8 thread size conforming to metric thread standard\u003c\/li\u003e\n\u003cli\u003eManufactured to DIN 7991 fastener standard\u003c\/li\u003e\n\u003cli\u003e316 austenitic stainless steel, Grade A4, for high corrosion resistance\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank for clearance-hole applications\u003c\/li\u003e\n\u003cli\u003eSold in a pack of 25 with a minimum order quantity of 1 pack\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 M5 tapped holes with 0.8 mm thread pitch in corrosion-resistant assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 3 mm hex socket driver or Allen key; confirm the mating hole is properly countersunk at 90 degrees to achieve full head seating.
