Key Features

• M4 Thread Size — These screws feature a standard M4 machine thread, making them compatible with the threaded mounting points found throughout Traxxas chassis, chassis plates, and assembly components. The precise pitch and thread profile ensure a secure, repeatable fit every time you install or reinstall them.
• 16mm Length — The 16mm length is engineered for specific Traxxas applications where deeper fastening is required, such as interior chassis assemblies, suspension linkages, and body mounting points. This length prevents over-tightening whilst providing sufficient engagement for a secure hold.
• Button-Head Profile — The distinctive rounded button head sits flush with components when fastened, providing a clean aesthetic finish whilst protecting the screw head from impact damage and snagging. This design is especially important for visible assembly areas on your RC model.
• Hex-Drive Head — The hex socket drive accepts standard hex keys and provides superior grip compared to Phillips or slot-head alternatives. This minimises the risk of cam-out or stripping the fastener head, which is critical when working with precision RC components that must be repeatedly maintained and adjusted.
• Black Finish — These screws feature a professional black finish that matches Traxxas components and provides a factory-authentic appearance throughout your model. The finish also offers enhanced corrosion resistance, which is essential for RC vehicles used in outdoor terrain or challenging weather conditions.
• Pack of Six — Each pack contains six individual screws, giving you sufficient spare capacity for multiple repairs, upgrades, or as consumable inventory in your RC maintenance kit. Having multiple spares means you're never caught short during a rebuild or when accident damage occurs.
• Genuine OEM Traxxas Parts — These are authentic original equipment manufacturer fasteners, ensuring they meet Traxxas engineering specifications and quality standards. Using genuine OEM screws guarantees compatibility and maintains the integrity of your Traxxas RC vehicle.

Technical Performance

The Traxxas Screws TRX3933 represent precision fastening engineering developed for the demands of high-performance RC vehicles. Manufactured to strict OEM specifications, these machine-thread screws deliver reliable performance across Traxxas' extensive product range, including brushless electric RC trucks, crawlers, and specialist models. The M4 x 16mm dimensions are carefully calculated to provide optimal engagement depth whilst maintaining component compatibility across multiple assembly points. The hex-drive mechanism distributes fastening force evenly across the socket, reducing stress concentration points and improving longevity compared to Phillips or slot-head alternatives. The black finish provides both aesthetic consistency with Traxxas' design language and practical corrosion resistance for RC vehicles subjected to outdoor use, moisture exposure, and thermal cycling. These screws are engineered to withstand the vibration, shock loads, and repeated fastening cycles that characterise modern brushless RC running, whether you're operating high-speed electric buggies, scale crawlers, or mammoth 8S monster trucks. The machine-thread profile ensures consistent thread engagement without the risk of stripping, which is essential for maintaining structural integrity through multiple maintenance cycles.

Frequently Asked Questions

• What models do these Traxxas screws fit? — These M4 x 16mm button-head screws are compatible with numerous Traxxas models including the Rustler Ultimate VXL, Sledge Belted monster truck, entire TRX-4 crawler range, X-Maxx series, and XRT models. Check your vehicle manual or contact us to confirm compatibility with your specific model, as Traxxas produces many variants and generations with different fastening requirements.
• Why should I use genuine OEM Traxxas fasteners instead of generic alternatives? — Genuine OEM Traxxas screws are engineered to exact specifications for your vehicle, ensuring proper fit, thread engagement, and structural integrity. Using non-genuine or incorrectly sized fasteners risks stripped threads, loose components, poor assembly alignment, and potential damage to expensive RC components. Authentic Traxxas parts maintain the engineering standards that make these vehicles reliable performers.
• Are these screws waterproof or weatherproof for outdoor use? — The black finish provides corrosion resistance suitable for typical outdoor RC use, though these screws themselves are metal fasteners and not sealed components. The water resistance of your vehicle depends on the overall design and sealing of internal electronics and bearing points. For vehicles used in wet conditions, ensure all appropriate waterproofing measures are in place on motors, servos, and ESC components.
• How often will I need replacement screws? — Regular maintenance typically involves removing and reinstalling screws multiple times during a vehicle's lifespan without requiring replacement. However, accident damage, over-tightening, or aggressive maintenance can strip threads or damage screw heads. Keeping spare screws in your maintenance kit ensures you're never stranded if a fastener becomes damaged.
• What tools do I need to install these screws? — These button-head machine screws feature hex-drive heads, so you'll need a hex key (Allen key) of the appropriate size to install or remove them. Traxxas typically includes the required hex tools with their vehicles, though having a quality precision hex key set is essential for any serious RC enthusiast maintaining brushless electric trucks and crawlers.
