Overview
The ARRMA Set Screw M4x35mm (4) is an essential hardware component for RC enthusiasts and model builders who demand precision and reliability in their machine. Whether you're maintaining your RC car UK setup, performing routine tune-ups, or undertaking a complete restoration project, these professional-grade set screws offer the exact specification needed for critical fastening applications. As a dedicated RC model shop, we understand that quality components are the foundation of any well-built RC vehicle, and these ARRMA-manufactured screws deliver the consistency and durability that serious hobbyists expect.
These set screws are specifically engineered for use with ARRMA's range of ready to run RC vehicles and competition models. With their precise M4 thread specification and 35mm length, they provide the perfect solution for applications requiring a grub-head fastener with hex driver compatibility. The pack contains four individually manufactured screws, each produced to exacting standards to ensure proper fit and secure fastening every single time you install them.
Whether you're a seasoned competitor preparing your vehicle for the track, a weekend basher maintaining your brushless RC truck, or a model builder undertaking detailed restoration work on your ARRMA collection, having quality replacement set screws on hand ensures you can quickly address any fastening requirement without compromising performance or safety.
Key Features
- M4 Thread Specification — The M4 metric thread size ensures compatibility with standard ARRMA RC vehicle mounting points and provides a secure, properly-tensioned connection that won't loosen under the vibration and stress of high-performance RC driving.
- 35mm Length — This specific length measurement makes these screws ideal for applications requiring deeper penetration into assembly points, ensuring maximum holding power for critical chassis and drivetrain components on your RC model.
- Grub Head Design — The grub-style head sits flush when installed, eliminating protrusions that could catch on components or create aerodynamic drag on your RC car, whilst maintaining a professional, clean appearance.
- Hex Driver Socket — The hex socket head allows for precise, controlled installation using standard hex key tools, preventing damage to the fastener and ensuring repeatable, correct fastening torque every time.
- Machine Thread Profile — These are engineered machine screws rather than wood screws, meaning they produce clean, consistent threads in pre-drilled holes and metal components, ideal for precision RC applications.
- Black Finish — The professional black coating provides corrosion resistance and protects against oxidation, particularly important if your RC vehicle is used in damp UK conditions or exposed to salt water environments.
- Pack of Four — With four screws included in each pack, you have spares for repairs, replacements, or multiple component assembly, reducing the need for multiple purchases and ensuring you're never caught without a critical fastener.
- ARRMA Quality Standard — Manufactured by ARRMA, a globally recognised brand in RC performance vehicles, these screws meet the same precision tolerances demanded by professional competition models and factory-built RTR vehicles.
Technical Performance
The ARRMA Set Screw M4x35mm represents the kind of precision engineering detail that separates well-maintained RC vehicles from those prone to mechanical failure. Every screw is manufactured to exacting tolerances, ensuring that when you install an M4 fastener into a pre-prepared hole, it seats perfectly without cross-threading, stripping, or requiring excessive force. The machine thread profile means these screws are designed for use in metal components and properly-tapped holes rather than forcing threads into soft materials, which would result in poor holding power and potential component damage. The hex socket head design allows for controlled fastening with a hex key, preventing the slip and damage that can occur with slot-head or Phillips-head fasteners under vibration. At 35mm length, these screws penetrate deeply enough to provide substantial holding power whilst remaining short enough for applications where longer fasteners would protrude or create interference with moving parts. The black finish provides protection against the elements, which is particularly valuable if you're running your brushless RC truck or high-performance RC buggy in the damp UK climate or near coastal areas where salt spray can cause rapid corrosion. These are precision components suitable for applications ranging from chassis assembly and suspension mounting to drivetrain component fastening, making them an essential part of any serious RC enthusiast's spare parts collection.

Frequently Asked Questions
- What ARRMA RC vehicles are these set screws compatible with? — These M4x35mm screws are confirmed compatible with the ARRMA INFRACTION 4X4 1/8 3S BLX Resto-Mod Truck RTR, which is available in both Teal and Gold colour options. However, given their standard M4 specification, they will also work with other ARRMA RC models that utilise M4 fastening points. We recommend checking your specific vehicle's documentation or contacting our team if you're unsure about compatibility with your particular model.
- Are these suitable for beginners working on RC vehicles? — Yes, absolutely. These set screws are straightforward to install using a standard hex key tool. Beginners will find them easier to work with than Phillips-head or slot-head fasteners because the hex socket prevents slipping and stripping. They're an excellent choice if you're learning to maintain and repair your RC car UK or undertaking your first customisation projects.
- What tools do I need to install these set screws? — You'll need a hex key (Allen key) in the appropriate size to fit the socket head. The specific hex size isn't detailed in the source specifications, so we recommend checking your vehicle's manual or contacting our team to confirm the exact key size required for your application.
- Can I use these screws for applications other than ARRMA vehicles? — The M4x35mm specification is a standard metric size, so these screws may be compatible with other RC brands and components that utilise M4 fastening points, including other brushless RC trucks, buggies, and scale models. However, we always recommend verifying compatibility with your specific vehicle or component manufacturer before installation.
- Why should I buy replacement set screws rather than reusing the originals? — Repeated removal and reinstallation of fasteners can damage the thread profile, especially in softer materials, leading to loose, insecure connections. Having fresh set screws on hand ensures optimal holding power, particularly important for high-vibration applications like RC driving where even slight loosening can lead to component failure and safety issues.
- What makes these ARRMA screws different from generic hardware store fasteners? — ARRMA manufactures these screws to the precise tolerances required for RC applications, ensuring consistent thread quality, proper fit in OEM mounting holes, and reliable performance under the unique stresses of RC vehicle operation. Generic fasteners may have looser tolerances, leading to poor fit and potential component damage.
