This four pack of 4mm purple flanged lock nuts from Jazrider provides a reliable, easy to fit fastening solution for common RC applications. The flange distributes clamp force and reduces stress on mate points, making these nuts a useful component for routine maintenance and practical upgrades.
The flange offers a larger bearing surface that helps prevent pull through on softer materials and gives a more secure seating under vibration. The purple finish aids quick identification in a mixed parts drawer or when working under time pressure.
These M4 flanged nuts are suitable for light mounting roles such as servo attachments, small bracket fastenings and finishing touches on custom assemblies. They are not a structural substitute for specialised hardware but are a sensible, durable choice for everyday hobby use.
