HKS FLANGE SELF LOCK NUT

When you're working on the engine, especially if you're rebuilding or replacing components, having the right hardware is crucial. This flange self-lock nut from HKS is designed to keep things securely fastened in critical areas.

This nut features a flange, which is a built-in washer that helps distribute the load over a wider surface area, preventing damage to the mating surface. The self-locking mechanism means it has a built-in locking feature, so it won't vibrate loose over time, which is especially important in a high-vibration environment like an engine bay. It's a well-built piece of hardware from a reputable brand known for performance parts.
