🔩 M2 Phillips Countersunk Machine Screws – Nickel or Black Zinc Plated, Fully Threaded (3–8mm Overall Length)
You’re fixing a tiny electronic device, mounting a small PCB, or repairing a laptop – and you need an M2 screw that sits flush, drives easily, and won’t rust. These M2 countersunk screws are made from carbon steel with a choice of nickel or black zinc plating. The flat 90° head sinks perfectly into a pre‑drilled countersink, leaving a smooth, professional surface. The Phillips drive works with precision crosshead screwdrivers. Available in overall lengths from 3mm to 8mm (including the head). Fully threaded for maximum grip. Perfect for computers, mobile phones, cameras, model making, and any miniature assembly where a flush finish and corrosion resistance are required.
✨ Key Features – M2 Countersunk Phillips Screws
- 🔽 Countersunk flat head (90°) – Sits flush with the surface after proper countersinking. Smooth, snag‑free finish.
- 📏
Phillips drive – Standard cross recess works with precision screwdrivers (#00 or #0). Good torque control.
- 🎨 Two finish options – Bright nickel (silver, good corrosion resistance) or black zinc (matte, low‑glare). Both provide moderate rust protection.
- 💪 Carbon steel construction – Strong and durable for light‑duty fastening.
- 📏 M2 metric thread (2mm diameter) – Ideal for very small electronics, watches, and instruments.
- 📐 Overall lengths 3, 4, 5, 6, 8mm (including head) – Example: M2 x 5mm means total length from top of head to tip is 5mm. Fully threaded.
- 🔧 Widely used – Computers, mobile phones, cameras, model making, furniture decoration, and precision DIY.

❓ Frequently Asked Questions – M2 Countersunk Screws
1. How do I measure the length of a countersunk screw?
For countersunk screws, the length is measured overall – from the top of the head to the tip. So an “M2 x 5mm” screw has a total length of 5mm 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. For a flush finish, drill a matching 90° countersink hole. For M2, use a tiny countersink bit (or carefully use a larger drill bit).
3. Are these screws fully threaded? What about longer lengths?
Yes – all M2 screws in this range (3–8mm) are fully threaded from under the head to the tip, giving you maximum grip in shallow holes or when using nuts.
4. Will the nickel or black zinc plating rust? Can I use these screws outdoors?
Both finishes provide moderate corrosion resistance – fine for indoor use and occasional light outdoor exposure. For continuous outdoor or marine environments, we recommend stainless steel. For most electronic and indoor applications, these are perfectly adequate.
5. What screwdriver do I need for M2 Phillips screws?
Use a #000 or #00 Phillips precision screwdriver. Regular household drivers are too large. Always match the bit size 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 a standard M2 metric nut (0.4mm pitch). For very small sizes, we recommend tapping the hole directly for best results.
