Hello fellow SLAP pals. I usually just post stuff for sale on here but wanted to chime in on these "38 specials" axle nuts Ace has been hyping up and give my personal experience. I noticed when I first put the wheel on and tightened down the nut I could barely go more than a couple small turns or else the wheel wouldn't even spin, yet the nut was barely on the axle. Right off the bat I thought something was wrong with these. However, what I ended up doing is tightening down the nut a whole lot, so it was showing 2-3 threads on the outside and the wheel definitely could not even move, then I loosened them up and everything went back to normal. The nut was on the axle properly and locked, and the wheel with the axle washers on both sides spun like it should and still had just that tiny bit of play which I always do. So I think people may be having issues with these new nuts falling off because they don't do the trick I discovered, therefore it never locks onto the axle properly. Hope this helps, I skated for a long time today and they did not come loose, they seem legit. However, if they do start coming loose after many sessions I will report back.
