How to check the screw before you buy
- Check whether the mount uses a VESA pattern or a vendor bracket before buying screws.
- 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: for binding head screws, measure from under the head to the tip (countersunk heads are the exception: they are measured overall).
- The record states 12 mm. Going longer risks bottoming out or touching parts behind the hole; going shorter loses thread engagement.
- 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.
Common mix-ups with M4
- Robot vacuum, air purifier and baby monitor teardowns list screws by driver and length only — length is not a thread size.
- Parts lists that say 'Taptite T-20 screw' are naming the driver, not the thread - only trust the separate M-size callout.
