right I need a dog point grub screw like the one below but I have no idea on sizes.

All I know is that the one I need is

- 11-12mm In Total Lenght

- 3mm Dog Point End

- 8-9mm Thread Lenght

- 5mm Across The Thread Width

- 1mm Cpacing Between Threads

- Hex Socket For Allen Key.

Can anyone work anything out from this / or find the right grub screw for me.

It needs to fit AP coilovers (if anyone knows the size from them).

Thanks,

Pete.

If its 5mm across the thread then its going to be M5 ,also Because you say its 1mm between threads then it may be a fine M5 thread, This is because standard pitch (distance between peaks of thread) of an M5 thread is 0.8mm ,

I could probably knock you one up and get it sent out to you if you want, How do you know the size of it by the way? As in distance between threads etc,

Because I've got 3 already and need a fourth, so I measured one.

what did you measure with? to get the pitch like? thread gauge?

Ruler, measured between the threads.

Is this what I need?
