It is listed for service manual torque table: M5 3-6 Nm.
This entry is marked confirmed and comes from invacare.co.uk.
For reference, M5 is 5 mm across the threads at 0.8 mm pitch. The imperial size people confuse it with: #10-32 (4.83 mm) — the other common rack thread; check before mixing.

How to check the screw before you buy
- Where the manufacturer publishes a torque value, use a torque driver rather than feel.
- Diameter: across the threads an M5 screw measures about 5 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
- Pitch: 0.8 mm from one thread crest to the next (12.5 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 M5 heads take PH2 for Phillips and T25 for Torx, and a 4 mm hex key for socket heads; a bit that fits loosely will cam out and strip the head.
Common mix-ups with M5
- Wheelchair and mobility OEM screws specify an exact standard and strength class (ISO 7045 CL4.8, ISO 4762 CL12.9). Matching only the thread size can cause a failure under load.
- Carbon bosses strip easily: 2-4 Nm torque and the right length so the bolt doesn't bottom out.

Questions about Invacare Action3 NG wheelchair frame/axle fastener screws
- What size screw does Invacare Action3 NG wheelchair frame/axle fastener use?
- M5 for service manual torque table: M5 3-6 Nm.
- How long are the screws in Invacare Action3 NG wheelchair frame/axle fastener?
- None of the sources states a length. Remove one screw and measure it from under the head to the tip (overall for a countersunk head).
- What is the thread pitch of an M5 screw?
- 0.8 mm (coarse), which is the standard pitch for M5 machine screws; a 0.5 mm fine pitch exists but is uncommon. The tap drill is 4.2 mm and the normal clearance hole is 5.5 mm.
- What screwdriver do I need for Invacare Action3 NG wheelchair frame/axle fastener?
- The sources do not name the drive. For M5, Phillips heads normally take PH2 and Torx heads T25; socket heads take a 4 mm hex key.
- Can I use an imperial screw instead of M5?
- No. Imperial look-alike: #10-32 (4.83 mm) — the other common rack thread; check before mixing. Use a true M5 screw so it does not cross-thread or strip the hole.
- How tight should the M5 screw on Invacare Action3 NG wheelchair frame/axle fastener be?
- The source gives 3-6 Nm for service manual torque table: M5 3-6 Nm.
