Key Features
- Strong and durable steel construction — Made from quality steel material, these cap head hex machine screws are engineered to withstand the stresses and vibrations of RC driving, whether you're bashing casually or competing seriously with your RC monster truck or RC short course truck.
- Precision manufactured threads — The threads are manufactured to precise tolerances, ensuring consistent fit every time you assemble or reassemble components, which means faster servicing, easier maintenance, and reliable fastening performance that won't let you down during a race or bash session.
- Cap head hex configuration — The cap head design provides excellent grip surface for your hex driver, allowing you to apply proper torque without slipping, whilst the distinctive appearance makes these screws easy to identify and handle during maintenance of your RC car UK setup.
- M3 x 16mm metric specification — At 3mm diameter and 16mm overall length, these screws are sized perfectly for numerous ARRMA chassis and assembly points, making them one of the most commonly needed fasteners across the ARRMA range.
- Pack of 4 screws — Each pack contains four individual screws, providing multiple replacement options so you can tackle multiple repairs or maintain spare assemblies for your RC vehicles without needing to purchase multiple packs.
Technical Performance
These cap head hex machine screws are manufactured to professional standards using quality steel that resists corrosion and maintains structural integrity through repeated use, fastening cycles, and the occasional impact or vibration that comes with aggressive RC driving. The precision-engineered threads ensure that fastening is predictable and reliable, with no stripped threads or loose connections that could compromise your RC truck's structural integrity. The metric M3 specification means a 3mm diameter shaft with threads that grip securely into ARRMA chassis and component holes, whilst the 16mm overall length positions them perfectly for numerous assembly points across ARRMA's extensive model range, including 1/10 scale brushless RC monster trucks like the GRANITE, KRATON, SENTON and VORTEKS, 1/10 scale brushed models, and even larger scale vehicles including 1/7 and 1/8 scale RC buggies and stadium trucks. The cap head design isn't just aesthetic — it provides a wide gripping surface that distributes torque evenly and prevents the hex driver from slipping, which is crucial when you're servicing a vehicle after a day of racing or bashing. Whether you're replacing fasteners that have corroded, stripped, or simply gone missing, or building additional chassis assemblies from spare parts, these ARRMA screws deliver the quality and reliability that competitive and casual RC enthusiasts alike have come to expect from genuine manufacturer components.

Frequently Asked Questions
- Are these ARRMA screws compatible with my specific RC model? — Yes, these M3 x 16mm cap head hex machine screws are listed as compatible parts for dozens of ARRMA vehicles across 1/10, 1/7, and 1/8 scales, including popular models such as the BIG ROCK, FURY, GORGON, GRANITE, KRATON, OUTCAST, SENTON, VORTEKS, and TYPHON ranges. If you own any ARRMA ready to run RC truck, buggy, or stadium truck, there's a very good chance these screws will be compatible with at least some assembly points on your vehicle. We recommend checking your vehicle's manual or contacting our team if you need clarification on fitment to your specific model.
- Why would I need replacement cap head hex screws for my RC car? — During normal RC driving, vibration and impacts can loosen fasteners, and aggressive bashing or racing can cause screws to strip, bend, or go missing entirely. Having genuine ARRMA replacement screws means you can keep your RC vehicle in perfect working condition without ordering expensive complete replacement assemblies. Regular maintenance and the occasional fastener replacement are part of responsible RC vehicle ownership.
- What makes these better than generic machine screws? — These are genuine ARRMA-manufactured parts engineered specifically for ARRMA vehicles, with thread specifications and materials that match the original components perfectly. Using genuine parts ensures precise fit, proper torque characteristics, and longevity that generic fasteners simply cannot match. For anyone serious about maintaining their RC truck or RC buggy, genuine parts are the only choice.
- How many screws come in each pack and how many do I need? — Each pack contains four M3 x 16mm cap head hex machine screws. The number you'll need depends on which assembly or repair you're undertaking — some component replacements might need just one screw, whilst others might require multiple fasteners. Having a pack of four means you'll have spares for future servicing.
- Are these screws suitable for beginners? — Absolutely. These are simple fastening components with no complexity whatsoever, making them perfect for beginners learning to service and maintain their RC vehicles. Learning to properly install fasteners and apply appropriate torque is an essential skill for any RC enthusiast, and these quality screws from a trusted manufacturer like ARRMA are ideal for that learning process.
