Very wide to make maximum surface contact. Very aggressive stepping on contact surface to reduce unwanted movement. These wheel nuts are exactly what I’ve been looking for, for. Very long time. I run a slash 4x4 with a 3s 50c lipo. It generates a ton of torque and a big issue I’ve had is the nuts backing off little by little till I send a wheel flying down the street at 60mph. I do recommend red thread locket with these as they don’t have a nylon insert.
