Key Features

• Machine Thread Design — These screws feature precision machine thread construction that provides consistent grip and secure fastening, essential for holding components in place during aggressive driving, jumps, and high-speed runs.
• Flat-Head Profile — The flat-head design allows the screw to sit flush with the mounting surface, eliminating protrusions that could catch on terrain or cause damage during off-road driving or racing sequences.
• Hex-Drive Head — The hex (Allen key) drive system provides superior grip compared to Phillips or slot-drive alternatives, reducing the risk of stripping and ensuring reliable installation and removal every time you service your RC vehicle.
• M3 Size Specification — At M3 (3mm diameter) with 15mm length, these screws are perfectly proportioned for servo mounting, internal chassis fastening, and component assembly on mid-size RC vehicles including the Traxxas Slash and similar models.
• Black Finish — The black colour matches Traxxas components and chassis elements, maintaining the professional appearance of your RC build whilst resisting rust and corrosion in outdoor conditions.
• Set of Six — With six screws included in each pack, you have enough fasteners for multiple repairs or complete servo installations, making this a cost-effective spare parts solution for RC car maintenance.
• Genuine Traxxas OEM — These are authentic Traxxas manufacturer parts (part number 3646), guaranteeing compatibility with your Traxxas RC vehicle and delivering the quality standards you expect from the world-leading RC brand.

Technical Performance

These Traxxas machine screws represent precision engineering in fastener design, critical for maintaining the structural integrity of your RC vehicle. The M3 diameter with 15mm length has been specifically engineered for Traxxas applications where secure fastening of servo mechanisms, chassis panels, and internal components is essential. The machine thread profile (as opposed to wood screws or thread-forming alternatives) creates a consistent, repeatable grip that resists loosening during vibration and repeated use. The hex-drive head is manufactured to precise tolerances, ensuring that standard 3mm hex keys engage fully without slipping or stripping. Build quality is paramount in RC applications—loose fasteners can result in component failure, loss of vehicle control, or damage during jumps and rough terrain navigation. These genuine Traxxas screws deliver the reliability required for both casual weekend bashing with brushless RC trucks and competitive racing where every component must perform flawlessly. The black finish is applied using Traxxas-standard processes that resist corrosion from moisture, dirt, and the chemicals found in racing fuel and maintenance solvents. Whether you're repairing a ready-to-run RC car or maintaining a competition-grade build, these screws provide the fastening reliability that separates quality restorations from temporary fixes.

• Why should I use genuine Traxxas screws instead of generic fasteners? — Genuine Traxxas OEM screws are engineered to exact specifications for your specific RC vehicle, ensuring perfect fit and compatibility.

Using authentic Traxxas parts guarantees you're getting the exact same quality and engineering that went into your vehicle.
• What is the difference between machine screws and other screw types? — Machine screws feature uniform threading designed to work with pre-drilled holes and threaded inserts, delivering consistent grip and secure fastening.

• Are these screws suitable for beginners working on RC cars? — Yes, these machine screws are ideal for any RC enthusiast regardless of experience level. The hex-drive head design is easy to use with a standard hex key, and the 3x15mm size is forgiving for general servo mounting and chassis assembly. They're perfect replacement parts for maintaining your ready-to-run RC car without requiring specialist tools or expertise.
• How many screws do I need to complete a servo installation? — A typical servo installation on an RC vehicle requires two to four screws depending on the servo mount design. With six screws in this pack, you have enough for multiple servo installations, repairs, or to keep as spares for future maintenance.
