When you need dependable small hardware, this set of four 4mm flanged lock nuts in purple from Jazrider fits the bill. They provide a simple, low fuss way to lock down parts that see movement or vibration without needing exotic tools.
The integrated flange spreads clamping force and reduces point load on softer surfaces, which is handy on plastic shock towers and other delicate mounts. The bright purple finish makes them quick to identify during teardown and rebuild sessions.
These nuts are well suited to light duty mounting tasks such as securing servo arms, small motor brackets and custom 3D printed parts. Keep a set in your toolbox for routine maintenance and field repairs.
