eSet the universal joints (one is fixed with 2 x M3*10 inner hexagon screw and another is fixed with 2 x M3 screw). The diagonal supporting arm is fixed on universal joint (1 x M3*10 inner hexagon screw + 1 x M3 rubber-washer screw).
My questions are:
What is the length of the described "2 x M3" screws in the first half?
What exactly is an "M3 rubber-washer screw"?
Is there anyway I can get a close up of this part?
Thank you in advance.
