NUT - NYLOCK JAM 5/16-18 (Yale YT0230885)

A damaged lock nut can compromise the security of a bolted joint, leading to loosening under vibration. The Yale catalog reference YT0230885 identifies this aftermarket replacement part. This nut type uses a nylon insert to resist self-loosening, a plain mechanical function that maintains clamping force. A common failure consequence is gradual fastener backing out, which can cause component misalignment or detachment. Keeping a nylock jam nut in sound condition helps preserve assembly integrity in threaded connections. This part is a 5/16-18 thread size, categorized as a hardware nut.
