A silver screw head on a black panel or dark enclosure stands out immediately — and a protruding head on a flush-mount surface is both a snag point and an eyesore. These black zinc-plated Phillips countersunk flat head machine screws in M2, M2.5, and M3 solve both problems: the 90° tapered head sits flush with or below the surface, and the matte black zinc finish blends cleanly into dark enclosures, PC cases, and electronics assemblies.
Available in 24 size combinations from M2×3mm (0.12”) to M3×16mm (0.63”) — measured including the head per standard metric countersunk convention. Pack sizes from 10 to 500 pieces cover single repairs through production stock. The Phillips drive is compatible with standard PH0–PH1 precision screwdrivers.
Typical applications include PC case and electronics enclosure assembly, where a flush black finish is required (M3), laptop and precision electronics fastening (M2–M2.5), panel and bracket mounting, where the head must sit flush (M2.5–M3), and workshop stock for the most common black countersunk micro fastener sizes.

For countersunk screws, length is measured including the head (total length). The screw should sit flush with or just below the surface when fully driven into a properly countersunk hole at 90°. Available lengths: 3mm (0.12”) to 16mm (0.63”) depending on the diameter. When in doubt, size up.
Black zinc plating (black zinc electroplating) provides corrosion resistance and a matte black finish. It reduces light reflection and gives a clean, low-profile appearance suitable for PC builds, dark enclosures, and electronics assemblies where a silver screw head would stand out.
A Phillips precision screwdriver: PH0 for M2–M2.5, PH1 for M3. Always use a well-fitting driver to avoid stripping, especially on M2 and M2.5 sizes. A quality precision screwdriver set is strongly recommended for M2 screws.
These screws use a 90° countersunk head angle, which is the standard for metric machine screws (DIN 965 / ISO 7046). Ensure your material has a properly countersunk hole at 90° for a flush fit. A 82° countersunk hole (US standard for imperial screws) will not give a flush result.
Yes. M2–M2.5 are standard sizes for laptop and precision electronics assembly. M3 is widely used in PC cases, electronics enclosures, and panel mounting. The black finish suits dark builds where a flush, low-visibility fastener is preferred.
Yes — these are machine screws, not self-tapping. They require a pre-tapped M-series hole or a matching metric nut in the same thread size. They will not cut their own thread into plastic or metal.
Available in packs of 10, 20, 50, 100, and 500 pieces. The 100 and 500-piece packs offer the best per-unit value for workshops and production use. Select your preferred quantity using the Amount option above.
