These four 4mm purple flanged lock nuts from Jazrider are a straightforward answer to loose fittings. They give a broader seating area than plain nuts and are handy for routine maintenance, upgrades and custom assemblies.
The wider contact of the flange helps avoid concentrated stress that can deform parts. That makes these nuts a sensible choice where components face continual vibration or repeated removal and refit.
Suitable for light duty mounting tasks such as securing small motors, fixing servo horns and tightening brackets on scale and 1/10 models. Keep a set in your spares box for quick roadside fixes.
