When your fastening job calls for a dark, low‑profile finish that still cuts its own thread, these black zinc Phillips pan head self‑tapping screws are exactly what you need. Precision‑machined from hardened carbon steel and finished in matte black zinc, they provide dependable corrosion resistance for indoor electronics, RC models, metal brackets, and appliance repair. The sharp, fully‑formed self‑tapping thread penetrates sheet metal, plastic, wood, and composites without a pilot hole in most thin materials, making assembly faster and cleaner. The classic pan head sits nearly flush, and the Phillips recess grips your driver firmly to prevent cam‑out. Offered in eight precise metric diameters — M1, M1.2, M1.4, M1.7, M2, M2.2, M2.6, and M3 — this micro‑range covers everything from eyeglass screws to light‑duty brackets.
| Size | Thread Diameter (d) | Head Diameter (dk) | Head Thickness (k) | Typical Lengths (mm)* | Head Style | Drive | Material & Finish |
|---|---|---|---|---|---|---|---|
| M1 | 1.0 mm | 1.7 mm | 0.6 mm | 3 – 6 | Pan Head | Phillips | Carbon Steel, Black Zinc |
| M1.2 | 1.2 mm | 1.9 mm | 0.6 mm | 3 – 8 | Pan Head | Phillips | Carbon Steel, Black Zinc |
| M1.4 | 1.4 mm | 2.3 mm | 0.8 mm | 3 – 10 | Pan Head | Phillips | Carbon Steel, Black Zinc |
| M1.7 | 1.7 mm | 3.1 mm | 1.0 mm | 4 – 12 | Pan Head | Phillips | Carbon Steel, Black Zinc |
| M2 | 2.0 mm | 3.4 mm | 1.3 mm | 4 – 16 | Pan Head | Phillips | Carbon Steel, Black Zinc |
| M2.2 | 2.2 mm | 3.8 mm | 1.5 mm | 5 – 20 | Pan Head | Phillips | Carbon Steel, Black Zinc |
| M2.6 | 2.6 mm | 4.2 mm | 1.7 mm | 6 – 25 | Pan Head | Phillips | Carbon Steel, Black Zinc |
| M3 | 3.0 mm | 5.3 mm | 1.9 mm | 6 – 30 | Pan Head | Phillips | Carbon Steel, Black Zinc |
* Lengths are thread length only (measured from under the head). Exact length options vary per size — choose from the listing drop‑down. Head dimensions follow GB/T equivalent standards.
Black zinc provides strong surface protection against mild moisture and oxidation. It won’t peel like paint, and in normal indoor or light outdoor use, it holds up well. For constant wet environments, consider stainless steel, but for electronics and hobby projects, the black finish stays clean and low‑profile.
In very thin sheet metal (up to ~0.8 mm), soft plastics, and wood, you can drive them directly. For thicker or harder materials, a small pilot hole — about 80% of the thread diameter — will reduce driving torque and help prevent snapping the smallest sizes (M1–M1.4).
No. All listed lengths are the thread length only, measured from directly under the pan head to the tip. This makes it easy to know exactly how much material the screw will go through.
The smallest sizes (M1–M1.4) require a #0 Phillips precision bit. M1.7–M2.2 use #0 or #1, and M2.6–M3 generally use a #1 bit. Using a sharp, well‑fitting bit prevents cam‑out and preserves the screw head.
