Dumb question of the day...UL1 Motor Screw size?

As the title says...can anyone help me out. You would think after 20 years of RC Boats I would know this.

m3, the length depends on the thickness of the motor mount, you don't want the stem to be too long to damage the copper windings of the stator. I use M3x8 ( 8mm length).

Thanks.. That's what I thought.
