The YIKONG YK4107 RC Car Parts Pan Head Hex Socket Screws M3×26 (21141) may become loose due to continuous vibration, especially during off-road driving, jumps, or rough terrain. Using incorrect tightening methods, insufficient thread engagement, or installing screws without proper thread locking on metal-to-metal connections can also increase the risk of loosening.
To prevent this issue, make sure the screws are tightened evenly with the correct hex driver. For metal-to-metal connections, apply a small amount of medium-strength (blue) thread locker. Regularly checking the screws after off-road sessions helps keep your YIKONG YK4107 RC Car components securely assembled.
