1.3mm hex grub screw for encoder knob, OG tracker

Hi I finally got round to replacing the encoder and managed to get the wrong one that’s stepless but it seems to work ok. The only issue now is I lost the tiny Allen key/hex screw that secures the large metal knob to the new encoder.

Anyone know the exact model of screw I need? Is it a M2.5?

I’m in the UK anyone got a link or idea what one I should buy?

Thanks.

I think it is a M3 x 3mm grub screw? But i‘m not entirely sure.

I‘ve already passed the question on to Polyend and will update here once i know more! :flexed_biceps:

It‘s a M2.5 x 6 DIN 913 BK according to Polyend:

That’s amazing I couldn’t find this any where thanks you!
