❓ Frequently Asked Questions – Flat Head Machine Screws for Laptops
1. How do I measure the length of a flat head (countersunk) screw?
For flat head screws, length is measured overall – from the top of the head to the tip. So an “M3 x 6mm” screw has a total length of 6mm including the head. This is the standard for countersunk fasteners.
2. Are these screws fully threaded?
Yes – all screws in this range (M2 to M8, up to 50mm) are fully threaded from under the head to the tip, giving you maximum grip in shallow holes or when using nuts.
3. Can I use these screws to replace stripped laptop case screws?
Absolutely. Many laptops use M2, M2.5, or M3 flat head screws for bottom covers and internal components. Check your original screw for diameter and length, then select the matching size from our dropdown.
4. Do I need a countersink to make the head flush?
Yes – these are true 90° countersunk screws. To achieve a flush finish, the hole must have a matching 90° countersink. Most laptop case screw holes are already countersunk – just replace the screw.
5. What screwdriver should I use for M2–M8 Phillips screws?
For M2–M2.5: #00 or #0 Phillips. M3–M4: #0 or #1. M5–M6: #2. M8: #2 or #3. Always use a driver that fits snugly to avoid cam‑out and head damage.
6. Can I use these screws for other applications besides laptops?
Yes – they are also perfect for tablets, smartphones, mechanical models, furniture assembly, industrial equipment repairs, and small device installations. The A2 stainless steel makes them suitable for outdoor and humid environments too.
