Koswork 3x25mm Hex Hardened Steel RC Screw Set (8) - KOSSS325

The Koswork KOSSS325 is a set of 3x25mm hardened steel hex set screws designed for use in RC cars and buggies where secure, reliable fastening is essential. Set screws of this type are commonly used to lock components such as motor pinions, wheel hexes, and drive shafts in place, preventing slippage under load. Hardened steel construction gives these screws significantly greater resistance to stripping and shearing compared to standard mild steel fasteners, making them a practical choice for anyone maintaining or building a competition or high-use RC vehicle.
