Hi !
Does anyone know what the thread size is on the 2.2Kw 80mm RedLine spindle collet nut ? Is it 24mm X 1.0mm ? I was shopping for collet nuts and there’s also 24mm x 1mm, 25mm x 1.5mm, etc…
Don’t want to screw my spindle up 
thanks!
I am sure they use ER20-A which are the 25 X 1.5 mm.
Add them to your cart, but wait for Onefinity to confirm…or someone with the spindle, as the size is often stamped/printed on the bottom of the nut.

25x1.5 for the hex type nut. The 24mm is on the er20 mini, which has slots on it for a special spanner.
