This coarse thread slotted nut is a 7/8"-9 castellated/slotted nut designed to be secured with a cotter pin through a drilled bolt or spindle, helping prevent loosening in rotating or vibration-prone assemblies. It’s a common hardware choice for axles, hubs, and other mechanical applications where positive locking is needed.
