We are all sick of stripping hexes. It's one of the worst feelings, because you know the work and money involved in removing the tire, buying new wheels, just to do it again. I have been gluing my hexes in and it worked until this week when I finally stripped one. Other's have turned to upgrading to 17mm, but that's not cheap and wheel selection is limited, not to mention modding the wheels and/or tires. Here is my solution, which only takes 15 minutes or less for all four.
One stripped JConcepts Rulux, a 12mm hex and an M2x6mm cap head screw.
Using a 5/64 bit, drill a hole through the side of the hex perpendicular to the pin notches (see last photo in post). It must be slightly forward of center.
Screw in your cap head screw just until you see it poke out in the hole. You want it flush on the inside.
Using an exacto or box cutter, notch your wheel hex. Smaller is better. It's easier to widen it as needed. Go all the way down to the flat part inside the hex.
Insert your newly modded hex. It should sit flat in the wheel. Use an L wrench if you need to tighten the screw down a bit. Just make sure it's not sticking out in the hole. You could put another screw on the opposite side for extra strength and security.
