It is, which means they are load-bearing screws - if I were to use something with a larger angle like the Banggood screws, they may not be able to take the radial loading of the hub → sleeve, which could cause issues.
I appreciate your help and research though. I feel like we are closer but maybe they just had to go and make a custom one. Which sounds SOL to me because Landwheel is kinda dissolved. Unless @pkasanda has some extras laying around or if Jason from Landwheel does, then this is gonna be tough.
I’ll measure the pitch again and when I get around to it I can check and see if an M3 fits the threading.
This seems like a recipe for a runaway sleeve lol
