M2*5mm Motor Mounting Screws (motor screws)
These stainless steel hex screws are commonly known in the hobby as motor screws. However these are 5mm long instead of the classic 4mm.
They are intended to be used with 3d printed flywheel cages and/or metal/cast plastic cages combined with the Silicone Motor Spacers.
You need 2 screws per motor, so total 4 per cage but I sell them in packs of 5 so you have a spare one.
