Zodiac Vortex 3 Saphir robotic pool cleaner screw size
M4 · 25 mm long
Zodiac Vortex 3 Saphir robotic pool cleaner takes M4 metric screws, 25 mm long.
It is listed for genuine OEM spare part is an A2 stainless steel pan head Pozi machine screw explicitly specified as M4×25 mm, used in the robot's structural assembly.
Head and drive, as the source states them: pan head and Pozidriv drive.
This entry is marked confirmed and comes from poolparthub.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
- Into printed plastic, the screw either self-taps or needs a heat-set insert; machine screws straight into plastic strip easily.
- 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 pan head screws, measure from under the head to the tip (countersunk heads are the exception: they are measured overall).
- The record states 25 mm. Going longer risks bottoming out or touching parts behind the hole; going shorter loses thread engagement.
- Driver: the source names a Pozidriv drive. For comparison, standard M4 heads take PH2 (Phillips) or T20 (Torx), or a 3 mm hex key.
- 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
- Camera rig/cage accessories (SmallRig, Wooden Camera/Metabones) frequently mix M4 structural screws with 1/4-20 and 3/8-16 imperial mounting points on the same product — verify which specific fastener a manual is referencing before ordering replacements.
- Grounding-lug screws on Siemens and Beckhoff gear (M4) are earth hardware, not structural mounting screws — don't reuse them to hold a module.

Questions about Zodiac Vortex 3 Saphir robotic pool cleaner screws
- What size screw does Zodiac Vortex 3 Saphir robotic pool cleaner use?
- M4 × 25 mm for genuine OEM spare part is an A2 stainless steel pan head Pozi machine screw explicitly specified as M4×25 mm, used in the robot's structural assembly.
- How long are the screws in Zodiac Vortex 3 Saphir robotic pool cleaner?
- The record gives 25 mm. Measure the original from under the head (overall for a countersunk head) to confirm before ordering.
- 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 Zodiac Vortex 3 Saphir robotic pool cleaner?
- The source lists a Pozidriv drive. Standard M4 heads otherwise take PH2 (Phillips) or T20 (Torx), or 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.
