I was just wondering if anyone has a preference of the type of Loctite they apply to VEX screws. I’m looking for a way to fasten the small, long screws into the motors without them falling out (at each competition and even when practicing I’ve had where the two screws on both drive motors fall out, and I DO NOT want that to happen in Dallas. And yes, thread locker IS legal). However, I would still need to unscrew them with the Allen wrenches in case I need to repair the motors (but I just don’t want them vibrating out, so Loctite is the best bet).
There are several variants of locktite thread locker available but the type you will most likely be selecting from at the store is the red or the blue version. The blue is temporary or removable while the red is permanent or not-easily-removable. We have used both on various screws during our robot builds however I recommend using the blue on the motor screws. Either red or blue is good for the other structural screws. Make sure you don’t go crazy with it because a little dab will do ya. By the way, teflon tape is not allowed according to the competition rules.
This is what we use. It is low strength so you can get it out. It is purple.
The one issue is that it will ruin plastic, particularly the small black plastic spacers. We have had issues in the past at getting all the other versions apart.
