For anyone serious about maintaining their RC hobby or building the perfect RC setup, having a collection of quality fasteners is essential for avoiding delays and ensuring every repair or upgrade goes smoothly.
Key Features
- M4x30mm Specification — This metric size provides the ideal balance between holding power and compatibility for a wide range of RC applications, making these screws suitable for suspension mounts, chassis connections, and other critical fastening points on RC models.
- Cap Head Design — The distinctive cap head profile allows for easy access and removal using a hex driver, whilst providing a clean, professional appearance to your RC build and ensuring positive engagement during installation and removal.
- Machine Thread — Precision machine threading guarantees consistent engagement with threaded holes and fastening points, eliminating the frustration of stripped threads or loose connections that can compromise your RC vehicle's performance and reliability.
- Hex Driver Type — Compatible with standard hex driver tools, these screws make installation and maintenance straightforward, requiring only basic RC tools that any RC enthusiast should have in their workshop.
- Pack of Four — With four screws included, you'll have spares for repairs, replacements, or future upgrades to your RC collection, ensuring you're always prepared for maintenance on your RC car or truck.
- Black Finish — The black coating provides both aesthetic consistency with ARRMA RC models and added corrosion resistance for durability, particularly important if you're using your RC vehicle in outdoor or damp conditions.
- OEM Quality — As genuine ARRMA components, these screws meet manufacturer specifications and quality standards, guaranteeing compatibility and performance across ARRMA's range of RC vehicles and potential compatibility with other RC platforms.
Technical Performance
These ARRMA Cap Head Screws represent precision engineering at the fastener level, a detail that separates casual RC hobbyists from committed builders who understand that vehicle reliability depends on every component, no matter how small. The M4x30mm dimension provides substantial holding power whilst remaining practical for the scale of most RC vehicles, from 1/8 scale buggies to larger rock crawlers and monster trucks. The machine thread design ensures that when you insert the screw into a properly tapped hole, you experience immediate, solid engagement without wobbling or cross-threading—a critical factor when working on precision RC models where tight tolerances are essential. The black finish isn't merely cosmetic; it provides a layer of protection against corrosion and oxidation, particularly valuable for RC enthusiasts who take their vehicles off-road or use them in variable weather conditions across the UK. The hex driver compatibility means these screws work with the standard Allen keys or hex bits found in most RC toolkits, and the cap head profile provides sufficient surface area for positive tool engagement, reducing the risk of stripping the drive and ruining the screw during removal—a frustration any RC builder has experienced. Whether you're reassembling a modified RC chassis, installing new suspension components, or performing scheduled maintenance on your ARRMA RC model, these screws deliver the reliability and precision expected from genuine manufacturer components.

Frequently Asked Questions
- Are these screws compatible with ARRMA Outcast 4X4 8S BLX and other ARRMA models? — Yes, these cap head screws are genuine ARRMA components specifically engineered for compatibility with ARRMA RC vehicles. The source confirms compatibility with the ARRMA 1/5 Outcast 4X4 8S BLX EXB Brushless Stunt Truck RTR, though M4x30mm screws are applicable across many ARRMA platforms requiring this specification for suspension, chassis, and structural fastening.
- What is the difference between cap head screws and other types of RC screws? — Cap head screws feature a distinctive cylindrical head with a hex drive, distinguishing them from flat-head, pan-head, or button-head screws. This design provides excellent load distribution, is easy to grip and remove using standard hex drivers, and offers a clean appearance on finished RC models. They're ideal for applications where access is straightforward and strength is important.
- Why should I choose genuine ARRMA screws over generic alternatives? — Genuine ARRMA cap head screws are manufactured to precise specifications, ensuring perfect fitment in ARRMA-designed fastening points and maintaining the integrity of your RC vehicle. Generic screws may have slightly different dimensions, thread pitches, or materials that could result in poor fitment, loosening during use, or difficulty with removal—compromising your RC model's reliability and your enjoyment.
- How many screws will I need for a typical RC model? — This depends on your specific RC model and intended modifications. The pack of four provides spares for replacement, repair, and future upgrades. Many RC builders keep multiple packs of fasteners in various sizes on hand for ongoing maintenance and customisation of their RC collection.
- What tools do I need to install these screws? — You'll need a hex driver or Allen key that fits the M4 cap head. Most RC tool kits include a set of metric hex drivers, making installation straightforward for anyone experienced with RC maintenance. Ensure your threaded hole is properly tapped and clean before installation.
