Overview
The ARRMA M3x11.5mm Motor Screw Set Z-ARA311171 is an essential replacement spare part for RC enthusiasts who own ARRMA brushless monster trucks, desert trucks, and short course trucks. This genuine OEM spare component is specifically engineered to secure your brushless motor to the chassis, ensuring reliable performance during high-speed runs and competitive racing. Whether you're a weekend basher enjoying high-octane RC fun or a serious competitor pushing your machine to the limit, having quality motor fasteners on hand is crucial for maintaining your RC car UK investment.
ARRMA has established itself as a leading manufacturer of high-performance RC vehicles, and their spare parts maintain the same exacting standards as their ready-to-run RTR models. The M3x11.5mm motor screw set is specifically compatible with a comprehensive range of ARRMA's most popular brushless RC trucks, including the legendary BIG ROCK 223S, GRANITE 223S, SENTON 223S, and the impressive MOJAVE 4X4 desert truck. This compatibility across multiple scales and vehicle types makes it an invaluable addition to any serious RC enthusiast's spares box.
Motor screws are subject to significant stress during operation, particularly when driving over rough terrain or during high-speed acceleration. The vibration and shock loads transmitted through your RC truck's chassis can gradually loosen fasteners, potentially leading to motor misalignment or loss of critical components. Having a dedicated replacement screw set ensures you can maintain peak performance and extend the lifespan of your brushless motor and associated electronics.

Frequently Asked Questions
- Which ARRMA RC trucks are compatible with the M3x11.5mm Motor Screw Set? — This screw set is compatible with six popular ARRMA brushless models: the 1/10 BIG ROCK 223S DSC 4X4 RTR (available in Black, Blue, and Green), the 1/10 GRANITE 223S DSC 4X4 RTR (available in Blue, Gun Metal, and Red), the 1/8 MOJAVE 4X4 4S BLX Desert Truck RTR (available in Blue and White), and the 1/10 SENTON 223S BLX Brushless 4X4 Short Course Truck RTR (available in Red, Yellow, and Blue/Purple). If you own any of these ready-to-run brushless RC trucks, this screw set will provide compatible replacement fasteners.
- Why do I need replacement motor screws for my brushless RC truck? — Motor screws secure your brushless motor directly to the chassis and experience continuous stress from acceleration, deceleration, and terrain vibration. Over time, fasteners can loosen, be stripped during maintenance, or occasionally be lost during field use. Having a dedicated replacement screw set ensures you can quickly restore your RC truck to full functionality without waiting for spare parts orders, keeping your brushless RC car UK ready for action.
- Are these genuine ARRMA parts or aftermarket alternatives? — These are genuine ARRMA OEM (Original Equipment Manufacturer) motor screws manufactured to ARRMA's exact specifications. Using genuine spare parts ensures perfect fitment and compatibility with your brushless RC truck, avoiding potential clearance issues or sub-standard fastening that might occur with generic alternatives.
- What size is this screw set and why does that matter? — The M3x11.5mm specification means a metric thread size of 3mm diameter with 11.5mm overall length. This precise sizing is critical because it's engineered specifically for ARRMA's motor mounting bracket depth and the threaded inserts in the chassis. Using correctly sized fasteners ensures proper engagement without stripped threads or components that protrude and interfere with moving parts.
- Can I use these screws on other RC brands or models? — These motor screws are specifically engineered for ARRMA's motor mounting system and the six compatible models listed. While M3 fasteners are common in RC vehicles, using them on different brands could result in improper fitment, poor thread engagement, or interference with other components. Always use manufacturer-specific spare parts for optimal performance and reliability.
- How many screws come in this set? — The source material specifies this is the Motor Screw Set but does not detail the exact quantity of individual screws included. For specific information about screw quantity, we recommend contacting our team of experienced RC enthusiasts at RC Model Shop, who can provide complete details about the exact contents and help you determine if additional fasteners are needed for your repairs.
