Quick question on the legality of nylon standoffs.
Certain non-VEX screws, nuts, and washers are allowed. Robots may use any commercially available #4, #6, #8, M3, M3.5, or M4 screw up to 2” (50.8mm) long (nominal), and any commercially available nut, washer, and/or spacer (up to 2” / 50.8mm long) to fit these screws.

As noted in R12, it will ultimately be at the inspector's discretion to determine whether or not a nylon screw has introduced additional functionality. In general, if the screw could be replaced with a standard VEX screw with no resulting functional changes to the mechanism in question, then they would be legal. However, if the mechanism takes advantage of a functional difference between the two screws (such as the additional flexibility of a nylon vs metal fastener), then they would likely be ruled illegal.

...standoffs are not considered nuts.
Should standoffs be considered nuts when interpreting R12 and Q&A 747?
