The HKS M8-1.25 self-locking nut is a single replacement fastener meant to restore secure clamp or bracket connections during maintenance. As a lock nut, it helps resist loosening under vibration when reassembling engine or turbo hardware. Keep spare locking nuts available when servicing components that require thread-locking reliability for safe, long-term operation.
