Unnoficial answer to Screw Length

[Ethan_W]

Here is the ruling in the game manual

<R7> Robots are allowed the following additional “non-VEX” components:
c. Any commercially available #4, #6, #8, M2, M2.5, M3 or M4 screw up to 2" long, and any
commercially available nut and/or washer to fit these screws.

Just use .5 standoffs with a nylock on both sides to make a longer screw for whatever you want. it’s way better than shafts for joints
