Dell Inspiron 13 5390 Wifi screw size

Dell Inspiron 13 5390 Wifi screw specifications

One row per fitment record. Head, drive are shown only where the source states them; pitch is the ISO coarse pitch for the thread.

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 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.
3. 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.
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 2–6 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 M1.6 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.
7. 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.

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.

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.
