HP E24d G4 / E27d G4 monitor screw size
M3 / M4 · 3 to 10 mm long
Our records put HP E24d G4 / E27d G4 monitor on M3 and M4 screws in lengths from 3 to 10 mm.
There are 5 separate fitment records for it, including internal chassis frame machine screws (14) (M3), interface and power board pan-head screws (10) (M3) and small bracket retention screws (2) (M3), plus 2 more in the table below.
Head and drive, as the sources state them: pan head.
5 of the 5 records are marked confirmed, drawn from 1 source (HP E24d/E27d G4 Maintenance and Service Guide).
For reference, M3 is 3 mm across the threads at 0.5 mm pitch. The imperial size people confuse it with: #5-40 (3.18 mm) or #4-40 — neither interchanges with M3.

How to check the screw before you buy
- VESA holes are threaded inserts in the back cover; if a screw stops early, back it out rather than forcing it, because a bottomed-out screw can crack the panel housing.
- Diameter: across the threads an M3 screw measures about 3 mm with calipers (usually a hair under). This device also uses M4, so measure each screw rather than assuming they match.
- Pitch: 0.5 mm from one thread crest to the next (20 crests per centimetre). A thread pitch gauge or the pitch-gauge tool settles it in seconds.
- Length: for pan head screws, measure from under the head to the tip (countersunk heads are the exception: they are measured overall).
- The records span 3–10 mm, which means different positions take different lengths — match each hole to its own screw.
- Driver: the source does not name the drive. Standard M3 heads take PH1 for Phillips and T10 for Torx, and a 2.5 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 M3 is about 80-130 N·cm into metal threads and 35-60 N·cm into plastic bosses; snug it up and stop.
Common mix-ups with M3 / M4
- Power-tool gearcase and clamshell screws are usually thread-forming (marked "ST") even when the parts list gives an M-size — a normal machine screw of the same size may not hold in the plastic boss.
- Many gas-detector and sensor manuals only give a torque spec (e.g. '0.5 N·m max') without repeating the thread size at every mention — the explicit M3 callout is usually only in the accessories/spare-parts table, not the main installation steps.
- Festo sensor brackets are named after the sensor interface (DASP-M4-...), but the bracket's own fixing screws are often a different size (M5/M6/M8).
- Some rackmount KVM switch kits pair M4x10 bracket-to-rack screws with M3.2x4.5 bracket-to-chassis screws (non-standard M3.2, not a true M3), so kits are not fully interchangeable with generic M3/M4 hardware.

Questions about HP E24d G4 / E27d G4 monitor screws
- What size screw does HP E24d G4 / E27d G4 monitor use?
- M3 × 3 mm for internal chassis frame machine screws (14); M3 × 6 mm for interface and power board pan-head screws (10); M3 × 4 mm for small bracket retention screws (2); M4 × 10 mm for back cover / main housing screws (4); M4 × 9 mm for power washer screw, ground / power board.
- How long are the screws in HP E24d G4 / E27d G4 monitor?
- The records range from 3 to 10 mm depending on the position, so match each screw to its own hole.
- What is the thread pitch of an M3 screw?
- 0.5 mm (coarse), which is the standard pitch for M3 machine screws; a 0.35 mm fine pitch exists but is uncommon. The tap drill is 2.5 mm and the normal clearance hole is 3.4 mm.
- What screwdriver do I need for HP E24d G4 / E27d G4 monitor?
- The sources do not name the drive. For M3, Phillips heads normally take PH1 and Torx heads T10; socket heads take a 2.5 mm hex key.
- Can I use an imperial screw instead of M3?
- No. Imperial look-alike: #5-40 (3.18 mm) or #4-40 — neither interchanges with M3. Use a true M3 screw so it does not cross-thread or strip the hole.
- Where can I buy replacement screws for HP E24d G4 / E27d G4 monitor?
- TechSpareWarehouse (our own store) lists M3 x 3mm, M3 x 6mm and M3 x 4mm, which match lengths in the records above.
