(10) #0-80 thread, plated steel jam nuts to use on your HO scale slot car axles. Direct replacement parts for use on vintage threaded axles that were commonly found on AFX, Aurora, Tyco and AJ's (to name a few) slot cars. They're the same as the originals, but steel instead of brass. I do have brass ones listed separately as well. Look through the pictures carefully because they provide a better description of the items actual condition than I can. If you have any questions, please ask them prior to purchase. Thanks!
