47: Non-Vex Screws & Nuts - aluminum / nylon


24365A
9-Aug-2018

<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 (nominal), and any commercially available nut and/or washer to fit these screws. The intent of the rule is to allow teams to purchase their own commodity hardware without introducing additional functionality not found in standard VEX equipment. It is up to inspectors to determine whether the non-VEX hardware has introduced additional functionality or not.

Are we allowed to use aluminum and nylon/plastic screws & nuts (examples below) as long as they are commercially available, are sizes listed above, and are only up to 2" long?

Yes, these would be legal.

In general, as long as the screws do not provide additional functionality beyond a standard screw (such as an eye bolt), "any screw" means "any screw". Properties like material type or color are irrelevant.
