This is a set of 2.5x11mm shoulder screws designed for RC chassis applications where a controlled pivot or offset mounting point is required. Unlike standard straight screws, shoulder screws include an unthreaded “shoulder” section that helps guide or space components while allowing smooth movement or precise alignment. In RC use, they are commonly found in suspension-related or steering-adjacent mounting points where parts need to rotate or sit with consistent spacing without binding. The IMX16399 is typically used in structural areas where precision fitment and strength are both required, such as linkage mounts or chassis connection points. The shoulder design helps reduce wear on plastic parts and improves durability under repeated movement and vibration.
