This Yokomo YOKZCN3APB 3mm aluminum hex nut is supplied in a pack of four and finished in blue anodize. It matches standard 3mm threaded fasteners used throughout model assemblies and is intended to secure wheel hubs, body mounts and other small connection points.
Installation: Engage the nut onto the matching 3mm stud or screw and tighten until secure using the correct hex driver or wrench. Avoid excessive torque to prevent thread damage, especially when fastening into softer materials. Apply thread-lock only where the assembly specifies it.
Tuning role: In tuning and setup, these nuts provide reliable clamping and are often used to mark key adjustments or to visually distinguish upgraded hardware during maintenance.
