NUT - SLTD HE M16-1.5 9N (Nissan NI01412-20016)

A damaged slotted nut can compromise threaded joint security, leading to loosening under vibration. This aftermarket replacement part references Nissan catalog number NI01412-20016. The nut is a slotted hex type with M16 thread size and 1.5 mm pitch, rated at strength grade 9N. Its primary mechanical function is to secure a fastener by engaging a cotter pin through the slots. A common failure consequence is that a worn or stripped nut may allow the assembly to separate unexpectedly. During service, checking the nut's slot condition helps prevent fastener loss.
