🔩 M2–M4 Flanged Button Head Phillips Screws – Black Zinc or Nickel Plated Carbon Steel

These flanged button head screws combine a low‑profile dome with an integrated washer – no more hunting for separate washers. The wide flange distributes clamping pressure evenly, making them perfect for plastic panels, sheet metal, and electronics enclosures. Choose black zinc for a stealth, matte finish or nickel for a bright, corrosion‑resistant surface. Made from high‑strength carbon steel with your choice of plating, they offer solid durability for indoor and light outdoor use. Available in M2, M2.5, M3, and M4, with lengths from 3mm to 16mm (under head). The Phillips drive centers easily and resists cam‑out – ideal for quick assembly work.

✨ Why These Flanged Button Head Screws Belong in Your Shop

🔧 Integrated flange (built‑in washer) – Saves time and ensures consistent clamping. No loose washers to drop or misplace.
⚫ Two durable finishes – Black zinc (matte, mild corrosion protection) or nickel (bright, higher corrosion resistance). Choose the look and protection level you need.
📏
Phillips drive with self‑centering cross – The cross recess helps center the bit, reduces wobble, and prevents drilling at odd angles. Fast, firm locking without slipping.
💪 High‑strength carbon steel – Stronger than low‑grade steel. Good toughness and wear resistance for long service life.
📏 Compact metric sizes M2 to M4 – Perfect for small electronics, 3D printers, RC models, appliances, and furniture repairs. Lengths from 3mm to 16mm (under head).
🏭 Wide application range – Furniture connection and repairs, chemical machinery, wind power, home appliances, office equipment, electronic devices, ship assembly, communications industry.

❓ Frequently Asked Questions – Flanged Button Head Screws (M2–M4)

1. What’s the advantage of a flanged button head over a regular pan head?

The flange acts as a built‑in washer – wider bearing surface prevents pull‑through in soft materials like plastic or thin sheet metal. The button head has a lower profile than a standard pan head, so it’s less obtrusive. Plus, you never lose a separate washer.

2. Which finish is more corrosion resistant – black zinc or nickel?

Nickel plating generally offers better corrosion resistance, especially in humid or slightly wet environments. It also has a bright, decorative appearance. Black zinc provides mild protection and a matte, stealth look. For outdoor use in damp conditions, choose nickel. For indoor or dry environments, black zinc is fine.

3. Can I use these screws with nuts or into tapped holes?

Yes – they are standard machine screws. Use them with matching metric nuts (M2, M2.5, M3, M4) or into pre‑tapped holes. The flange often eliminates the need for a washer on the screw side, but you may still want a flat washer under the nut.

4. What Phillips bit size do I need for these screws?

M2–M2.5 use PH0, M3–M4 use PH1 or PH2 (PH1 fits better). Using the correct bit prevents stripping and ensures full torque transfer.

5. Are these screws fully threaded?

For all lengths listed (3–16mm), these screws are fully threaded. The thread runs continuously from just under the head to the tip. This provides maximum grip in thin materials.

6. Can I use these screws outdoors?

Nickel plated version is suitable for light outdoor use (e.g., covered patio furniture, garden tool repairs). Black zinc is more for indoor use. Neither is as corrosion‑resistant as stainless steel. For full outdoor exposure or coastal areas, we recommend A2 or A4 stainless screws.
