Product description Keep Your RC Adventure Going with the Lukaisen 638PCS Heavy-Duty Screw Set Every RC enthusiast knows the frustration: a weekend bash is cut short by a single stripped screw or a lost body pin. Cheap, soft hardware just doesn't cut it when you're pushing your crawler to the limit. That's why we engineered the Lukaisen 10.9 Grade Carbon Steel Kit—the toughest hardware upgrade for your RC fleet. Why Choose 10.9 Grade Carbon Steel? Standard stainless steel is great for rust but often too soft for the high-vibration, high-torque environment of an RC motor mount or chassis. Our 10.9 grade screws provide the tensile strength required to prevent head stripping and snapping, ensuring your expensive upgrades stay securely attached during jumps and tumbles. Designed for the "Basher" Lifestyle We didn't just include screws. We included everything that gets lost or broken: lock nuts that won't vibrate loose, R-pins that actually stay in place, and O-rings for your shock absorbers. It’s a complete field-repair solution in one compact, organized box. Package Content Highlights: M3 & M4 Screws: 10.9 Grade (Round/Flat Head, multiple lengths) Set Screws: For secure pinion gear attachment Hardware Extras: Washers, Hex Nuts, R-Pins, Solid Pins, E-Clips Maintenance Tools: 1.5mm, 2.0mm, 2.5mm Nickel-plated Hex Wrenches O-Rings: 30PCS M262 for shock and seal maintenance Note: These are high-strength carbon steel. For best results, keep the storage box in a dry environment and apply a thin layer of oil after cleaning your RC car with water.
