In the game manual, it states:
<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.
Does that mean it is legal to use nylon screws as they are commercially available?
