Cap head screws are fundamental components in RC vehicle assembly and maintenance. They secure critical chassis components, body panels, suspension mounts and other vital assemblies that keep your brushless RC truck or electric RC car operating safely and efficiently. The M4x35mm specification makes these screws ideal for medium-duty applications across ARRMA's range of 1/5 scale off-road RC models. Whether you're rebuilding after a crash, performing routine maintenance, or building a new RC vehicle from scratch, having genuine ARRMA fasteners on hand means you can get back to enjoying your hobby without delays.
As a trusted UK RC retailer, RC Model Shop stocks authentic ARRMA spare parts and accessories to support your RC hobby. These cap head screws represent the quality and attention to detail you expect from ARRMA, one of the most respected manufacturers in the RC car UK market. With their distinctive hexagonal drive socket, cap head screws offer superior grip and reduced risk of stripping compared to standard slotted fasteners, making them the preferred choice for precision RC work.
Key Features
- Machine Thread Construction — These screws utilise machine thread design, which provides consistent, reliable engagement with threaded holes and ensures secure fastening without requiring a nut, making installation quicker and more convenient when working on your RC model.
- M4 Diameter with 35mm Length — The M4x35mm specification is precisely engineered to fit ARRMA's design requirements, ensuring perfect compatibility with mounting points throughout your RC truck, RC buggy or RC crawler without risk of incorrect sizing or fitment issues.
- Hexagonal Cap Head Design — The distinctive cap head shape with hexagonal socket provides a large bearing surface that distributes clamping force evenly, reducing the risk of pulling through soft materials whilst the hex socket driver ensures a secure, positive grip that minimises the chance of stripping or slipping during installation.
- Black Finish — The black colour coating protects against corrosion and provides a professional appearance that matches ARRMA's standard aesthetic across their RC vehicle range, whether you're restoring an existing model or customising your RC car.
- Pack of Four — Each pack contains four screws, providing sufficient fasteners for multiple repair jobs, component replacement, or building new assemblies without needing to purchase multiple packs for common maintenance tasks.
- Genuine ARRMA Component — These are authentic manufacturer fasteners rather than generic alternatives, guaranteeing the exact metallurgy, thread pitch, and dimensional accuracy required for safe operation of your ARRMA RC vehicle.
Technical Performance
The ARRMA Cap Head Screw M4x35mm represents precision engineering in fastener design. The M4 diameter (4 millimetre nominal diameter) combined with the 35 millimetre length provides an ideal balance between holding power and installation depth for ARRMA's 1/5 scale RC trucks and buggies. The machine thread type creates a strong, permanent connection when fastened into pre-threaded holes, eliminating the need for washers or nuts on most applications. The hexagonal socket head design delivers superior torque transmission compared to Phillips or slot-head alternatives, reducing the likelihood of bit slippage that could damage both the screw and your RC model. The black finish provides corrosion resistance, which is especially important when operating your RC car in damp UK conditions or after water crossings common in RC crawling and off-road RC racing. Whether you're performing scheduled maintenance on your brushless RC truck, repairing damage from aggressive bashing, or assembling new components, these genuine ARRMA fasteners ensure your RC vehicle maintains structural integrity and reliable performance across all driving conditions.

Frequently Asked Questions
- What is a cap head screw and why does my RC truck need them? — Cap head screws, also called socket head cap screws, are fasteners with a cylindrical head containing a hexagonal socket. They're essential in RC vehicles because they secure critical components like suspension mounts, body posts, chassis braces and drivetrain elements. The larger bearing surface of the cap head distributes clamping force more effectively than traditional screws, reducing the risk of pulling through softer materials common in RC plastic chassis and composite bodies. They also provide superior grip for your hex key driver, minimising the chance of stripping the socket during assembly and disassembly.
- Will these screws fit my ARRMA RC model? — The M4x35mm specification is designed specifically for ARRMA vehicles. The pack lists compatibility with the ARRMA 1/5 Outcast 4X4 8S BLX EXB Brushless Stunt Truck RTR, though they're suitable for other ARRMA models with M4 threaded holes at this depth. Always check your vehicle's manual or contact RC Model Shop to confirm compatibility with your specific RC truck or buggy before purchase.
- What tools do I need to install these screws? — You'll need a hexagonal Allen key (hex wrench) in the appropriate size to fit the socket head of the M4 cap head screw. ARRMA typically uses standard metric hex sizes, and most hobby tool sets include the necessary driver. Avoid over-tightening, as this can strip the threads in softer materials commonly used in RC vehicle chassis.
- How many screws do I need? — This pack contains four screws, which typically covers one or two component replacements or repairs on an ARRMA RC vehicle. For major rebuilds or if you're building multiple RC models, you may wish to order several packs to ensure you have sufficient fasteners. Keeping spare screws in your RC spares box is essential for uninterrupted hobby enjoyment.
- Are genuine ARRMA screws better than generic fasteners? — Yes, genuine ARRMA components are manufactured to exacting standards with precise thread pitch, metallurgical composition and dimensional accuracy. Generic fasteners may have inconsistent quality, incorrect thread specifications, or substandard materials that could fail under the vibration and stress encountered in RC racing or bashing. Using genuine manufacturer parts ensures your RC vehicle remains safe and reliable.
- Can I use these screws on other RC brands? — Whilst the M4x35mm specification is a standard metric size that may fit some other RC vehicles, always verify compatibility before use. Different manufacturers may use slightly different thread pitches or hole depths. Stick with genuine ARRMA fasteners for ARRMA vehicles to guarantee perfect fitment and safe operation of your RC truck or buggy.
