Dell Precision 3560 screw size

M2 / M2.5 · 2 to 5 mm long

The screws used on Dell Precision 3560 are M2 and M2.5 in lengths from 2 to 5 mm.

There are 20 separate fitment records for it, including keyboard (qty 26) (M2), power button (qty 2) (M2) and LED board (qty 1) (M2), plus 17 more in the table below.

20 of the 20 records are marked confirmed, drawn from 1 source (dl.dell.com).

For reference, M2 is 2 mm across the threads at 0.4 mm pitch. The imperial size people confuse it with: #2-56 UNC (2.18 mm) is close but not interchangeable.

How to check the screw before you buy

  1. Laptop covers and brackets often mix two or three lengths of the same thread, so lay the screws out in the order they came out (a magnetic mat or a sheet of paper with the hole pattern drawn on it works).
  2. Diameter: across the threads an M2 screw measures about 2 mm with calipers (usually a hair under). This device also uses M2.5, so measure each screw rather than assuming they match.
  3. Pitch: 0.4 mm from one thread crest to the next (25 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 2–5 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 M2 heads take PH0 for Phillips and T6 for Torx, and a 1.5 mm hex key for socket heads; 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 M2 is about 25-40 N·cm into metal threads and 12-20 N·cm into plastic bosses; snug it up and stop.

Common mix-ups with M2 / M2.5

  • M.2 SSD mounting screws (M2 x 3mm) are frequently mislabeled generically as 'M.2 screws' which can be confused with the M2 metric thread designation — they do coincide numerically here but are conceptually distinct (M.2 = card format, M2 = thread size).
  • 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.
  • M2.5 and M3 look the same to the naked eye — you need calipers on the shank to tell them apart.

Questions about Dell Precision 3560 screws

What size screw does Dell Precision 3560 use?
M2 × 2 mm for keyboard (qty 26); M2 × 2 mm for power button (qty 2); M2 × 3 mm for LED board (qty 1); M2 × 3 mm for bracket (qty 2); M2 × 3 mm for card reader (qty 2); M2 × 3 mm for chassis/frame (qty 12); M2 × 3 mm for display (qty 2); M2 × 3 mm for fan (qty 2); M2 × 3 mm for heat sink (qty 1); M2 × 3 mm for power button (qty 1); M2 × 3 mm for system board (qty 3); M2 × 4 mm for battery (qty 3); M2 × 4 mm for SSD (qty 1); M2 × 4 mm for USB-C board (qty 3); M2 × 5 mm for fan (qty 2); M2.5 × 3.5 mm for display (qty 4); M2.5 × 3.5 mm for hinge (qty 4); M2.5 × 3.5 mm for unspecified (qty 4); M2.5 × 5 mm for display (qty 6); M2.5 × 5 mm for hinge (qty 6).
How long are the screws in Dell Precision 3560?
The records range from 2 to 5 mm depending on the position, so match each screw to its own hole.
What is the thread pitch of an M2 screw?
0.4 mm (coarse), which is the standard pitch for M2 machine screws; a 0.25 mm fine pitch exists but is uncommon. The tap drill is 1.6 mm and the normal clearance hole is 2.4 mm.
What screwdriver do I need for Dell Precision 3560?
The sources do not name the drive. For M2, Phillips heads normally take PH0 and Torx heads T6; socket heads take a 1.5 mm hex key.
Can I use an imperial screw instead of M2?
No. Imperial look-alike: #2-56 UNC (2.18 mm) is close but not interchangeable. Use a true M2 screw so it does not cross-thread or strip the hole.
Where can I buy replacement screws for Dell Precision 3560?
TechSpareWarehouse (our own store) lists M2 x 2mm, M2 x 3mm and M2 x 4mm, which match lengths in the records above.
