Elesa NT-HD-SST hygienic sealed screw knob screw size
M4 · length not stated in the sources
If you are replacing a screw on Elesa NT-HD-SST hygienic sealed screw knob, the thread is M4. None of the sources we found gives an exact length, so measure the original before you order.
It is listed for variant NT-HD-SST-M4-MT-H.
This entry is marked confirmed and comes from elesa.com.
For reference, M4 is 4 mm across the threads at 0.7 mm pitch. The imperial size people confuse it with: #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.
- 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
- Dashcam mounts advertised as '1/4" M4 screw joint' have two different threads: the 1/4"-20 camera thread and a separate M4 grub screw for the ball joint — don't order the wrong one.
- 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.
