How long are the screws in CubeSat Kit solar panel clips and chassis?

The records range from 4 to 5 mm depending on the position, so match each screw to its own hole.

What is the thread pitch of an M3 screw?

0.5 mm (coarse), which is the standard pitch for M3 machine screws; a 0.35 mm fine pitch exists but is uncommon. The tap drill is 2.5 mm and the normal clearance hole is 3.4 mm.

What screwdriver do I need for CubeSat Kit solar panel clips and chassis?

The sources do not name the drive. For M3, Phillips heads normally take PH1 and Torx heads T10; socket heads take a 2.5 mm hex key.

Can I use an imperial screw instead of M3?

No. Imperial look-alike: #5-40 (3.18 mm) or #4-40 — neither interchanges with M3. Use a true M3 screw so it does not cross-thread or strip the hole.

Where can I buy replacement screws for CubeSat Kit solar panel clips and chassis?

TechSpareWarehouse (our own store) lists M3 x 4mm and M3 x 5mm, which match lengths in the records above.

CubeSat Kit solar panel clips and chassis screw size

M3 · 4 to 5 mm long

CubeSat Kit solar panel clips and chassis takes M3 metric screws in lengths from 4 to 5 mm.

Where it is used: non-standard solar panel clip fixed with an M3 x 4 mm pan-head stainless screw and lock washer; base plate to chassis walls and cover plate each use six M3 x 5 screws.

Head and drive, as the source states them: pan head.

This entry is marked confirmed and comes from cubesatkit.com.

For reference, M3 is 3 mm across the threads at 0.5 mm pitch. The imperial size people confuse it with: #5-40 (3.18 mm) or #4-40 — neither interchanges with M3.

How to check the screw before you buy

If several screws hold the same part, check that they are all the same length before assuming they are.
Diameter: across the threads an M3 screw measures about 3 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
Pitch: 0.5 mm from one thread crest to the next (20 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 records span 4–5 mm, which means different positions take different lengths — match each hole to its own screw.
Driver: the source does not name the drive. Standard M3 heads take PH1 for Phillips and T10 for Torx, and a 2.5 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 M3 is about 80-130 N·cm into metal threads and 35-60 N·cm into plastic bosses; snug it up and stop.

Common mix-ups with M3

Part numbers can embed a thread code (e.g. ifm fibre fittings with 'M3') that refers to a fitting thread, not a chassis screw.
The bioprinter M3 reference is a tube-connector thread spec, not a structural chassis screw; verify before assuming interchangeability with fastener screws.
