Key Features

• Genuine Traxxas OEM Part — This is the authentic original equipment manufacturer screw designed by Traxxas engineers specifically for their RC vehicles, ensuring perfect compatibility and reliability that you simply cannot guarantee with aftermarket alternatives.
• Countersunk Head Design — The countersunk profile sits flush with the mounting surface, providing a clean appearance and ensuring components fit together properly without protruding fasteners interfering with movement or operation of your RC car.
• Hex Drive Head — The hex socket drive allows precise torque application using a hex wrench or Allen key, giving you excellent control when tightening or removing these screws without the risk of cam-out that can occur with Phillips or slot drives.
• Precise 3x20mm Dimensions — The 3mm diameter shaft and 20mm length are specifically engineered to fit Traxxas mounting points, providing the correct clamping force and thread engagement for structural integrity in high-stress RC applications.
• Machine Thread Type — These screws feature machine threads rather than wood or self-tapping threads, meaning they work with threaded inserts or pre-drilled holes for consistent, repeatable assembly every time you need to maintain your RC vehicle.
• Pack of Six — You receive six screws in each pack, giving you enough for typical repairs or maintenance jobs on your Traxxas RC car, with spares remaining for future use.

Technical Performance

These 3x20mm countersunk machine screws are engineered to the highest standards expected of Traxxas components. The combination of a 3mm diameter shaft and 20mm length provides optimal clamping force for the chassis, servo mounts, body posts, suspension components, and other critical assemblies found on modern Traxxas RC vehicles including the popular Rustler, Stampede, X-Maxx, and X-Monster chassis families. The hex drive head design delivers superior torque transfer compared to Phillips or slot-drive alternatives, reducing the risk of stripped heads during installation or removal—a critical advantage when working on valuable RC equipment. The countersunk profile ensures that when properly installed, the screw head sits flush with the mounting surface, maintaining the clean lines of your RC car and ensuring that adjacent components can move freely without obstruction. The machine thread design means these screws require pre-threaded holes or threaded inserts, which is exactly how Traxxas RC vehicles are designed. The black finish provides corrosion resistance for UK outdoor use, protecting the fasteners during wet conditions or salt-laden environments. With proper installation and maintenance, these genuine Traxxas screws will provide years of reliable service in both casual bashing and competitive racing applications.

Check your vehicle manual or contact our team if you're unsure whether these are compatible with your specific RC car.
• Can I use standard M3x20 screws from a hardware shop instead? — We strongly recommend against substituting these with generic hardware store screws. Traxxas parts are engineered with specific metallurgy, thread tolerances, and head geometry to ensure proper fit and function. Using non-genuine parts risks stripping threads, improper clamping force, and potential damage to your RC vehicle's components.
• How do I know if I need these screws? — If a screw has broken, become stripped, or been lost during maintenance of your Traxxas RC vehicle, or if you're building a new vehicle from parts, these genuine replacements ensure proper assembly. The 3x20mm size is clearly marked on Traxxas parts lists and manuals.
• Do these come with washers or springs? — These are the screws only. Depending on your application, you may need separate washers or lock washers, which are available as separate Traxxas parts. Consult your vehicle manual for specific assembly requirements.
• Are these suitable for beginners? — Yes, absolutely. Anyone maintaining, repairing, or building a Traxxas RC vehicle can use these screws with basic tools like a hex wrench. They require no special skills beyond careful hand-tightening to avoid over-torquing.
• What tools do I need to install these screws? — You will need a 3mm hex wrench or Allen key to tighten and remove these screws. A torque wrench calibrated to the specifications in your Traxxas manual ensures you apply the correct clamping force without damaging components.
