A2 Stainless Steel DIN 965 Countersunk Phillips Machine Screws — Extra Long Flush-Fit Fasteners for Demanding Applications
When a standard-length screw won't reach through thick panels, structural timbers, or stacked assemblies — and you still need a clean, flush finish — you need a fastener that combines reach with precision. These DIN 965 countersunk Phillips machine screws are engineered for builders, fabricators, and engineers who require a flush-seated, corrosion-resistant fastener in lengths that are genuinely hard to find off the shelf.
Manufactured from 304 stainless steel (Grade A2-70) with precision-rolled metric threads, these screws feature a 90° countersunk flat head that sits flush with or below the workpiece surface when driven into a pre-drilled countersunk hole. Available in thread sizes M2 through M12 and lengths from 30mm to 200mm (1.18" to 7.87"), covering micro-precision to heavy-duty structural applications.
Suited for furniture assembly, door and window hardware, marine deck fittings, industrial machinery frames, renewable energy installations, and any application where a flush, low-profile fastener with extended reach is required. The polished bright finish also suits visible or decorative fastening points.
✅
Compatible with standard metric tapped holes — M2 through M12. Driven with a Phillips (cross-recessed) screwdriver: PH1 for M2–M3, PH2 for M4–M6, PH3 for M8–M12.

Size Reference: Product images show measurement reference points only. Proportions in photos do not represent actual visual scale. Please refer strictly to the size parameters listed in the variant selector (e.g., M4*60 = M4 thread × 60mm length). A countersunk pilot hole is required for a flush finish.
❓ Frequently Asked Questions
What material are these screws made from?
These screws are made from 304 stainless steel (Grade A2-70), providing excellent corrosion resistance for indoor, outdoor, and light marine applications.
What standard do these screws conform to?
These screws conform to DIN 965, the standard for countersunk flat head Phillips (cross-recessed) machine screws with a flush-fit profile.
What sizes are available?
Available in metric thread sizes M2, M2.5, M3, M3.5, M4, M5, M6, M8, M10, and M12, with lengths typically ranging from 30mm to 200mm depending on the diameter. Select your exact size using the variant options above.
What does 'countersunk' mean and why does it matter?
A countersunk head has a tapered underside that sits flush with or below the surface of the material when driven into a pre-drilled countersunk hole. This eliminates protrusion, creating a smooth, snag-free surface — essential for furniture, panels, and any application where a clean finish is required.
What drive tool do I need?
These screws use a Phillips (cross-recessed) drive. A standard Phillips screwdriver or bit of the appropriate size is required: typically PH1 for M2–M3, PH2 for M4–M6, and PH3 for M8–M12.
Are these screws suitable for outdoor or marine use?
Yes. 304 stainless steel provides good resistance to atmospheric corrosion and oxidation, making these screws suitable for typical outdoor environments. For highly corrosive or saltwater marine environments, 316 stainless steel is generally recommended.
Why are these called 'extra long' screws?
These screws are offered in longer lengths than typically stocked in hardware stores, starting from 30mm and extending up to 200mm for M5 and M6 sizes. This makes them suitable for deep-seated fastening through thick materials such as structural timbers, stacked panels, or heavy machinery frames.
Do I need to pre-drill a countersunk hole?
Yes. For a flush finish, you should pre-drill a pilot hole and then use a countersink bit to create the tapered recess that matches the screw head angle (90° for DIN 965). This ensures the head sits level with the surface. Driving into an unprepared hole will leave the head proud of the surface.
