Technical Performance

The Traxxas 4x14mm Button-Head Machine Screws represent precision engineering at the component level, demonstrating the attention to detail that characterises Traxxas's approach to RC vehicle manufacturing. These machine screws are engineered to withstand the intense vibration, shock loads and dynamic stresses that occur in high-performance brushless RC vehicles operating at speed across rough terrain. Whether your RC buggy is tackling challenging off-road tracks, your short course truck is competing in stadium racing, or your monster truck is performing high-speed bashings, these fasteners maintain their grip through hundreds of cycles. The M4 size with 14mm length positions them for critical chassis and drivetrain assembly points where secure fastening is essential for vehicle integrity. The hexagonal drive design distributes clamping force evenly across the fastening point, reducing the risk of stripped heads or cross-threaded engagement—a common problem with inferior fasteners. The black finish provides UV resistance and corrosion protection, crucial for RC vehicles that may be stored outdoors or exposed to wet conditions during water crossing runs or after wet terrain bashings. These are not generic hardware store screws; they are manufactured to the exacting tolerances required by Traxxas to ensure that your brushless RC models perform reliably race after race and bash after bash.
