🔩 M2–M12 Countersunk Phillips Machine Screws – White / Colour Zinc Plated, Carbon Steel

You’re assembling a piece of furniture, installing a hinge, or fastening metal parts together – and you want a clean, flush finish that looks professional. These countersunk flat head screws sink perfectly into a pre‑drilled countersink, leaving a smooth surface with no snags. Made from high‑strength carbon steel with a choice of white zinc or colour zinc plating, they resist moderate corrosion and look great. The Phillips drive works with standard crosshead screwdrivers. Available in diameters from M2 up to M12, with a full range of lengths (select from dropdown). Fully threaded for maximum grip. Perfect for industrial use, furniture assembly, and decorative metalwork where a flush, rust‑resistant fastener is needed.

✨ Key Features – Countersunk Phillips Machine Screws (Zinc Plated)

🔽 Countersunk flat head (90°) – Sits flush with the surface after proper countersinking. No protruding heads – safe and professional.
📏
Phillips drive – Standard cross recess works with common screwdrivers. Good torque transfer with reduced cam‑out.
🎨 White or colour zinc plating – Choose bright white zinc for a clean, silver finish, or colour zinc (e.g., yellow, blue, black) for decorative or color‑coding needs.
💪 Carbon steel construction – High strength, good heat resistance, and durability. Zinc plating adds moderate corrosion protection.
📏 Wide metric range M2 to M12 – M2, M2.5, M3, M4, M5, M6, M8, M10, M12. Covers everything from tiny electronics to heavy machinery.
📐 Fully threaded, coarse pitch – Thread runs the entire length under the head. Maximum grip in blind holes or through‑nut applications.
🏭 Widely used – Industrial equipment, furniture assembly, automotive trim, decorative hardware, and metal part fastening.

❓ Frequently Asked Questions – Countersunk Zinc Plated Screws

1. How do I measure the length of a countersunk screw?

For countersunk flat head screws, the length is measured overall – from the top of the head to the tip. So an “M5 x 8mm” screw has a total length of 8mm including the head. This matches our listing.

2. Do I need to countersink the hole for these screws to sit flush?

Yes – these are true 90° countersunk screws. To achieve a flush or slightly recessed finish, drill a matching 90° countersink hole. Use a countersink bit of the appropriate size.

3. Are these screws fully threaded? What about longer lengths?

Yes – all screws in this range (up to the maximum length available) are fully threaded from under the head to the tip, giving you maximum grip in blind holes or through‑nut applications.

4. Will the zinc plating rust? Can I use these screws outdoors?

Zinc plating provides moderate corrosion resistance – fine for indoor use and occasional light outdoor exposure (e.g., garden furniture under cover). For continuous outdoor, marine, or high‑humidity environments, we recommend stainless steel screws. For most furniture, appliances, and indoor fastening, zinc plated screws are perfectly adequate.

5. What Phillips screwdriver size do I need for M2 to M12?

For M2–M2.5: #000 or #00; M3–M4: #0 or #1; M5–M6: #2; M8–M10: #2 or #3; M12: #3. Always use a driver that fits snugly to avoid cam‑out and head damage.

6. Can I use these screws with a nut? What size nut fits?

Yes – these are machine screws. Use standard metric nuts of the same thread size and pitch (e.g., M6 nut for M6 screw). They will also thread into pre‑tapped holes. Not self‑tapping – for wood or plastic, use a threaded insert or nut on the back.
