Thread pitch BRM 1/24 wheel grub screws

[noddaz]

That IS the question...
I need some grub screw and found that they are listed as 3x3mm.
But the secret is the thread pitch... Which I do not have a tool to measure...
.7 or .5?
Please help?

Seeing as nobody else is answering I will PITCH in.

Unless I am mistaken the standard for M3 is 0.5mm pitch with fine thread being 0.35mm: I have not seen reference to a .7mm pitch. As I believe it is possible to force a 4-40 screw in where a M3 is required and the thread pitch for that is 0.65mm I do not believe setscrews are fine thread.

Ergo: I believe the standard 0.5mm pitch should be it.
