When a standard pan head just isn’t wide enough, these Phillips flanged pan head self‑tapping screws give you a built‑in washer‑like bearing surface. The extra‑wide flange spreads clamping force more evenly, reducing the chance of pull‑through in thin sheet metal, plastic, or wood – without the trouble of adding separate washers. Made from hardened carbon steel with a clean black zinc finish, they offer reliable corrosion resistance for indoor electronics, automotive trim, furniture assembly, and general shop use. The sharp, coarse self‑tapping thread cuts its own path instantly as you drive, so there’s no need for pre‑tapped holes or nuts. Covering all common micro to small‑duty diameters from M1.2 up to M4 and lengths from 3 mm to 20 mm (excluding head), this range lets you stock your workbench with the exact sizes you reach for most.
| Thread Size | Thread Diameter | Available Lengths (mm)* | Head Style | Drive | Material & Finish |
|---|---|---|---|---|---|
| M1.2 | 1.2 mm | 3, 4, 5, 6 | Flanged Pan | Phillips | Carbon Steel, Black Zinc |
| M1.4 | 1.4 mm | 3, 4, 5, 6, 8 | Flanged Pan | Phillips | Carbon Steel, Black Zinc |
| M1.7 | 1.7 mm | 4, 5, 6, 8, 10 | Flanged Pan | Phillips | Carbon Steel, Black Zinc |
| M2 | 2.0 mm | 4, 5, 6, 8, 10, 12 | Flanged Pan | Phillips | Carbon Steel, Black Zinc |
| M2.3 | 2.3 mm | 5, 6, 8, 10, 12, 16 | Flanged Pan | Phillips | Carbon Steel, Black Zinc |
| M2.6 | 2.6 mm | 6, 8, 10, 12, 16 | Flanged Pan | Phillips | Carbon Steel, Black Zinc |
| M3 | 3.0 mm | 6, 8, 10, 12, 16, 20 | Flanged Pan | Phillips | Carbon Steel, Black Zinc |
| M4 | 4.0 mm | 8, 10, 12, 16, 20 | Flanged Pan | Phillips | Carbon Steel, Black Zinc |
* Lengths are thread length only (excluding head). Exact length options depend on the size selected. All screws conform to GB/T equivalent standards.
The flanged pan head has a wider, slightly raised bearing surface around the recess. It acts like a built‑in washer, spreading clamping force wider to resist pull‑through in thin sheet metal, plastic, or wood. You often don’t need a separate washer, which saves assembly time.
Black zinc provides good corrosion resistance for indoor and light outdoor use. It’s not marine‑grade, but it will resist everyday moisture and humidity. For damp environments, a light protective oil or occasional inspection will keep them looking fresh longer.
They are self‑tapping, meaning the thread will form its own path when driven. In thin sheet metal (up to about 1 mm) and soft plastics, you can drive them directly. For thicker metals or hardwoods, a small pilot hole makes driving easier and will extend the life of the thread.
Sizes M1.2–M2 generally take a #0 Phillips bit. M2.3–M3 use a #0 or #1, and M4 uses a #1 bit. Always use a bit that fits snugly – a worn bit can easily cam out and damage the head.
