I want to use 12mm hex wheels on my SCT 410.3. In a previous post it was recommended to use these.

Has anyone used these hex adapters, what retains the pin?
Does anyone know of a another method to use 12mm hex wheels?
I believe that those were recommended only if you are running the 8mm stub axles for the EB48SL https://www.teknorc.com/shop/tkr5570-17-17mm-hub-adapter-set-sct410-18-buggy-width-2pcs/
To answer your question on how the pins are held in place there is a grub screw that threads in the end of the stub axle.
My question for you, why do you need the 12mm hexes for your SCT410.3? The SCT410.3 comes with 12mm hexes. The parts below are what should come stock on a SCT410.3
