Dell Latitude 7520 screw size
M1.6 / M2 / M2.5 · 1.7 to 5 mm long
If you are replacing a screw on Dell Latitude 7520, the thread is M1.6, M2 and M2.5 in lengths from 1.7 to 5 mm.
There are 24 separate fitment records for it, including keyboard (qty 20) (M1.6), power button (qty 2) (M1.6) and display (qty 2) (M2), plus 21 more in the table below.
24 of the 24 records are marked confirmed, drawn from 1 source (dl.dell.com).
For reference, M1.6 is 1.6 mm across the threads at 0.35 mm pitch. The imperial size people confuse it with: #1-72 UNF (1.85 mm) is larger; there is no true imperial equivalent.

How to check the screw before you buy
- 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).
- Diameter: across the threads an M1.6 screw measures about 1.6 mm with calipers (usually a hair under). This device also uses M2 / M2.5, so measure each screw rather than assuming they match.
- Pitch: 0.35 mm from one thread crest to the next (28.57 crests per centimetre). A thread pitch gauge or the pitch-gauge tool settles it in seconds.
- Length: measure from under the head to the tip for pan, button, wafer and cap heads; countersunk (flat) heads are measured overall.
- The records span 1.7–5 mm, which means different positions take different lengths — match each hole to its own screw.
- Driver: the source does not name the drive. Standard M1.6 heads take PH00 for Phillips and T4–T5 for Torx, and a 1.5 mm hex key for socket heads; a bit that fits loosely will cam out and strip the head.
- Tightening: no device-specific torque is published in these records. The site's general figure for M1.6 is about 12-20 N·cm into metal threads and 6-10 N·cm into plastic bosses; snug it up and stop.
Common mix-ups with M1.6 / M2 / M2.5
- 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 Latitude 7520?
- The records range from 1.7 to 5 mm depending on the position, so match each screw to its own hole.
- What is the thread pitch of an M1.6 screw?
- 0.35 mm (coarse), which is the standard pitch for M1.6 machine screws; a 0.2 mm fine pitch exists but is uncommon. The tap drill is 1.25 mm and the normal clearance hole is 1.8 mm.
- What screwdriver do I need for Dell Latitude 7520?
- The sources do not name the drive. For M1.6, Phillips heads normally take PH00 and Torx heads T4–T5; socket heads take a 1.5 mm hex key.
- Can I use an imperial screw instead of M1.6?
- No. Imperial look-alike: #1-72 UNF (1.85 mm) is larger; there is no true imperial equivalent. Use a true M1.6 screw so it does not cross-thread or strip the hole.
- Where can I buy replacement screws for Dell Latitude 7520?
- TechSpareWarehouse (our own store) lists M2 x 2mm, M2 x 2.5mm and M2 x 3mm, which match lengths in the records above.
