The WA21-N003 is a Nylok lock nut from World American, sized M16-2.0. It interchanges with several common references including PTRHWC12501, 27-01223-016, ENC16MM, M5215, and PTR-HWC12501, making it a useful cross-reference part for hardware replacement. This nut uses a nylon insert to resist loosening from vibration, a common design for driveline and chassis hardware.
