Drive Shaft Nut Coarse Thread
This is the coarse thread 5/8 nut that threads onto the end of some drive shafts. Typically in upper drive shafts we find this thread pitch on early models. Lower direct drive crank assemblies almost always use this nut.
Installation Note : Be sure to use a thread locking agent such as RED LOC-TITE when installing this nut.
