Acer XR342CK screw size
M4 · 8 to 10 mm long
The screws used on Acer XR342CK are M4 in lengths from 8 to 10 mm.
There are 3 separate fitment records for it, including stand (qty 4) (M4), vesa mount (qty 4) (M4) and vesa mount (qty 4) (M4).
3 of the 3 records are marked confirmed, drawn from 1 source (global-download.acer.com).
An M4 screw is 4 mm in diameter with a 0.7 mm pitch, tapped with a 3.3 mm drill; imperial look-alike: #8-32 (4.17 mm) — the standard US PC/rack screw, close but not the same.

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 M4 screw measures about 4 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
- Pitch: 0.7 mm from one thread crest to the next (14.29 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 8–10 mm, which means different positions take different lengths — match each hole to its own screw.
- Driver: the source does not name the drive. Standard M4 heads take PH2 for Phillips and T20 for Torx, and a 3 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 M4 is about 2.0-3.0 N·m into metal threads and 0.8-1.4 N·m into plastic bosses; snug it up and stop.
Common mix-ups with M4
- VESA fixes the hole pattern and max thread depth, not screw length — length depends on the panel back and any spacers.
- VESA thread size is set by pattern class: M4 for 75x75/100x100, M6 or M8 for the big 200mm+ patterns. Check the plate on the back of the display.

Questions about Acer XR342CK screws

- M4 × 10 mm for stand (qty 4); M4 × 10 mm for vesa mount (qty 4); M4 × 8 mm for vesa mount (qty 4).
- How long are the screws in Acer XR342CK?
- The records range from 8 to 10 mm depending on the position, so match each screw to its own hole.
- What is the thread pitch of an M4 screw?
- 0.7 mm (coarse), which is the standard pitch for M4 machine screws; a 0.5 mm fine pitch exists but is uncommon. The tap drill is 3.3 mm and the normal clearance hole is 4.5 mm.
- What screwdriver do I need for Acer XR342CK?
- The sources do not name the drive. For M4, Phillips heads normally take PH2 and Torx heads T20; socket heads take a 3 mm hex key.
- Can I use an imperial screw instead of M4?
- No. Imperial look-alike: #8-32 (4.17 mm) — the standard US PC/rack screw, close but not the same. Use a true M4 screw so it does not cross-thread or strip the hole.
