How to check the screw before you buy

  1. A screw that is even 1 mm too long in a laptop base can push into the keyboard, battery or a board trace, so match the length position by position.
  2. Diameter: across the threads an M1.2 screw measures about 1.2 mm with calipers (usually a hair under). This device also uses M1.6 / M2 / M2.5 / M3, so measure each screw rather than assuming they match.
  3. Pitch: 0.25 mm from one thread crest to the next (40 crests per centimetre). A thread pitch gauge or the pitch-gauge tool settles it in seconds.
  4. Length: measure from under the head to the tip for pan, button, wafer and cap heads; countersunk (flat) heads are measured overall.
  5. The records span 1.9–9 mm, which means different positions take different lengths — match each hole to its own screw.
  6. Driver: the source does not name the drive. Standard M1.2 heads take PH000 / JIS 00 for Phillips and T1–T2 for Torx; a bit that fits loosely will cam out and strip the head.
  7. Tightening: no device-specific torque is published in these records. The site's general figure for M1.2 is about 5-8 N·cm into metal threads and 3-5 N·cm into plastic bosses; snug it up and stop.

Common mix-ups with M1.2 / M1.6 / M2 / M2.5 / M3

  • Framework lists both M1.2 x 3.0 silver and M1.6 x 3.0 black expansion-card screws; they look identical in the tray but are not interchangeable.
  • M1.6 is the most common laptop-internal micro screw after M2 — Dell XPS keyboards specifically call out M1.6 x 1.5mm, and generic M2 substitutes strip the bracket.
  • The standard M.2 SSD screw is M2 x 3mm, but some laptops and handhelds use non-standard lengths or head shapes.
  • Dell/HP/Lenovo manuals often list screws only by torque or head shape, so community teardowns are needed for diameter.

How long are the screws in Dell Alienware m17?
The records range from 1.9 to 9 mm depending on the position, so match each screw to its own hole.
What is the thread pitch of an M1.2 screw?
0.25 mm (coarse), which is the standard pitch for M1.2 machine screws. The tap drill is 0.95 mm and the normal clearance hole is 1.4 mm.
What screwdriver do I need for Dell Alienware m17?
The sources do not name the drive. For M1.2, Phillips heads normally take PH000 / JIS 00 and Torx heads T1–T2.
Can I use an imperial screw instead of M1.2?
No. Imperial look-alike: #0-80 UNF (1.52 mm) is the closest imperial screw, but it is bigger — not a substitute. Use a true M1.2 screw so it does not cross-thread or strip the hole.
Where can I buy replacement screws for Dell Alienware m17?
TechSpareWarehouse (our own store) lists M1.2 x 2mm, M2 x 2mm and M2 x 2.5mm, which match lengths in the records above.
