Koswork M4 Aluminium Serrated Nuts Black RC Nut - KOSN1005

The Koswork KOSN1005 M4 Aluminum Serrated Nuts are black anodised hardware components designed for use across a wide range of RC cars and buggies. Supplied in a set of eight with a storage container, these M4 serrated lock nuts resist vibration and help prevent fasteners from working loose during hard running. The serrated flange bites into the mating surface to maintain clamping force without relying on a nylon insert, making them a practical choice for areas of the car that see repeated heat or stress.
