Key Features

• Dual-pack content — This pack provides two different screw sizes in a single convenient package: 6 pieces of 3x28mm cap-head machine screws plus 6 pieces of 3x6mm ELW screws, giving you flexibility to address multiple fastening needs across your RC model.
• M3 machine thread specification — The screws feature precision machine threading on the M3 diameter, ensuring secure fastening and compatibility with standard M3 threaded holes found throughout Traxxas RC vehicles.
• Hex drive system — All screws in this pack feature hex (Allen key) drive heads, allowing you to use standard hex tools for installation and removal without stripping the heads, which is critical for repeated maintenance and adjustments.
• Cap-head design — The 3x28mm screws use a professional cap-head design that provides a clean, compact profile and sits flush once installed, ideal for areas where clearance is important or where you want a finished appearance on your RC car.
• Silver finish — The screws feature a silver metallic finish that provides excellent corrosion resistance, ensuring they remain reliable and functional even after exposure to moisture, dirt and the elements during outdoor RC car UK sessions.
• Genuine Traxxas manufacture — These are authentic factory-produced Traxxas fasteners, not third-party alternatives, guaranteeing they meet strict engineering standards and will fit perfectly with your Traxxas RC vehicle every time.
• Compact storage pack — The complete set comes in an organised package with both screw sizes clearly identified and separated, making it easy to store and locate exactly what you need when you require replacements.

Technical Performance

The Traxxas TRX3963 screw pack represents a fundamental but essential component of proper RC vehicle maintenance and repair. The 3x28mm cap-head machine screws are engineered to provide secure fastening with a low-profile cap head design that's ideal for sensitive areas of your RC car where space is at a premium. The M3 machine threading specification ensures compatibility with the threaded inserts and holes featured throughout Traxxas' range of brushless and electric RC vehicles, from entry-level ready to run models through to high-performance competition builds. The hex drive system eliminates the risk of stripping fasteners during installation or removal, a critical consideration when you're working on valuable RC equipment. Meanwhile, the 3x6mm ELW screws provide a smaller fastening option for securing components where the larger screws would be unsuitable. The silver finish applied to both screw types offers genuine corrosion protection, which is essential for maintaining reliability when your RC car is exposed to moisture, muddy conditions, or coastal salt-air environments common across the UK. Every screw in this pack has been manufactured to precise tolerances at Traxxas' production facilities, ensuring dimensional accuracy and material consistency that guarantees perfect fitment and reliable performance across multiple assembly and disassembly cycles.
