I have noticed in recent tournaments that some teams appear to have been using parts that originate from VRC field kits. I understand that polycarbonate can be legal assuming that it fits within the sizing restrictions but our question specifically centers around Nuts. Rule R11 gives a detailed explanation of legal fasteners for robots as listed which seems pretty straightforward.
Ive noticed that some teams may be using larger nuts as part of their endgame expansion projectiles that look like they could be the 1/4" lock nuts used in the VRC field perimeter. What i would like to clarify is whether these nuts are competition legal. the vex website lists the field perimeter as being VRC Legal under the V5 platform; however, i am unsure if this might fall into the bounds of the red box in rule R6 as listed below due to being "competiton support materials".
Clarification would be appreciated, thank you!
