Description
The Losi LOS3959 is a pack of ten set screws sized M4 x 5mm with a flat point design, constructed from strong steel alloy for consistent strength. Set screws thread into a hub, collar, or gear and press against a shaft to prevent unwanted rotation or slippage, and the flat point profile distributes contact pressure evenly across the mating surface for a stable, non-marring hold. Built to genuine Losi factory specifications, these fasteners provide dependable thread engagement and maintain their clamping force under the vibration and shock loads typical of RC driving. This hardware set serves as a direct factory replacement, making it suitable for routine maintenance, full rebuilds, or replacing set screws that have loosened, stripped, or been lost during regular use. The steel alloy construction resists rounding out at the hex socket, helping preserve reliable tool engagement over repeated adjustments. Ten pieces are included per package, giving you enough hardware to complete a repair or maintain a stock of spares for future work on your RC vehicle.
