Years ago I installed an anti-fade axle lock nut. Now I need to tighten it but the Allen bolt that runs through it has seized. I don't remember if I forgot to anti-seize it or it washed off or dried out. I'm planning to use a hacksaw blade to saw through the Allen bolt. Then I will be able to remove the locknut and evaluate whether to extract the bolt or go back to the stock locknuts that I have in the basement. That way I can see if the nut being loose was making the axle move or if I need new carrier bearings. Are these anti-fade locknuts worth keeping? The one I have just looks like a big nut with an allen in it, not the fancier kind that looks like a doorknob.
