Dell Pro 24 Plus monitor (P2425DE) screw size
M2 / M3 / M4 · 2 to 10 mm long
If you are replacing a screw on Dell Pro 24 Plus monitor (P2425DE), the thread is M2, M3 and M4 in lengths from 2 to 10 mm.
There are 5 separate fitment records for it, including keypad board screws (3) (M2), lens/proximity board screw (M2) and metal shield to panel (2) (M3), plus 2 more in the table below.
5 of the 5 records are marked confirmed, drawn from 1 source (cdn.iceshop.nl).
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
- For a wall or arm mount, the screw has to engage the threaded insert by several turns but must not bottom out, so measure the insert depth and add the thickness of the bracket and any spacers.
- Diameter: across the threads an M2 screw measures about 2 mm with calipers (usually a hair under). This device also uses M3 / M4, so measure each screw rather than assuming they match.
- 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.
- 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 2–10 mm, which means different positions take different lengths — match each hole to its own screw.
- 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.
- 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 / M3 / M4
- M2 (2.00mm, 0.4mm pitch) is NOT the same as #2-56 UNC (2.18mm) — close enough to cross-thread and strip if forced.
- LED strip clips strip easily — M3x12 into thin plastic should be hand-driven, never with a power driver.
- Display mounts mix systems: the screen side is metric M4/M6, but the wall side of many mounts uses imperial wood screws such as #14 x 2.5in.
