The 3RACING M4WD-18/BK socket button screw in black is a small but practical M2 x 5 fastener intended for Tamiya Mini 4WD models. It is a common spare used by hobbyists for tidy, secure fits around the chassis.
Use this socket button screw where a low-profile, reliable fix is needed, such as securing body posts, small brackets, or accessory mounts. The finish blends with darker kits for a cleaner look.
Install with the correct hex driver and avoid overtightening to protect plastic threads. Inspect screws after a run and replace if deformation is visible.
