Overview
The ARRMA Set Screw M4x8mm (10) is an essential replacement and maintenance component for RC car enthusiasts throughout the UK. Whether you're a serious competitor, a weekend basher, or new to the world of RC models, having a reliable stock of quality fasteners is crucial for keeping your RC vehicles in peak condition. Set screws are fundamental hardware components used across countless RC car assemblies, from suspension components to motor mounts and transmission parts. This genuine ARRMA pack contains 10 precision-engineered M4x8mm set screws, ensuring you have the right fasteners on hand whenever you need them.
When building or maintaining your RC car, using genuine manufacturer parts ensures perfect compatibility and reliability. ARRMA is recognised globally as one of the leading RC vehicle manufacturers, producing everything from entry-level ready-to-run models to competition-grade machines. Their attention to quality extends to every component, including these precision set screws. For RC enthusiasts in the UK looking to maintain their ARRMA vehicles or build custom setups, having genuine ARRMA fasteners ensures your build meets the manufacturer's specifications and performs as intended.
Set screws are small but vital components that hold numerous parts in place on your RC car. Unlike regular bolts that rely on a head to grip against a surface, set screws use their threaded length to create a secure connection, making them ideal for certain applications where space is limited or where a flush fit is required. The M4x8mm specification makes these versatile fasteners suitable for a wide range of ARRMA RC vehicles and custom projects.

Technical Performance
ARRMA set screws are engineered with precision manufacturing standards that ensure consistent quality across every unit in the pack. The M4x8mm specification represents a commonly used fastener size across the RC hobby, particularly for applications where a threaded fastener without a head is required. Steel construction provides excellent strength-to-weight ratio and resistance to corrosion under normal usage conditions. The thread form is precisely machined to ISO metric standards, ensuring smooth installation and reliable holding power without stripping. Whether you're performing routine maintenance on your RC car, replacing worn fasteners, or building a custom setup, having genuine ARRMA set screws ensures your assembly meets manufacturer specifications. These fasteners are suitable for use in various RC car applications where secure, flush connections are required, from motor mounting points to transmission components and beyond. The quality of these set screws directly impacts the reliability of your RC vehicle, as improper fastening can lead to component movement, misalignment, and ultimately poor performance or damage during operation.

Frequently Asked Questions
- What are set screws used for on RC cars? — Set screws are precision fasteners used to secure components in place where a flush fit is required or space is limited. On RC cars, they're commonly used for motor pinion retention, suspension mounting, transmission assembly and various other assembly points where a threaded fastener without a protruding head is ideal. Unlike regular bolts with external heads, set screws use their entire threaded length to grip and hold components securely.
- Why should I buy genuine ARRMA set screws instead of generic alternatives? — Genuine ARRMA fasteners are manufactured to the exact specifications that ARRMA RC vehicles are engineered for. Using authentic components ensures perfect compatibility, correct thread pitch, appropriate hardness and the right material composition. Generic fasteners may have slight dimensional variations that can lead to loose fits, stripped threads, or component movement during operation. For RC enthusiasts who want reliable performance and longevity from their vehicles, genuine manufacturer parts are always the better choice.
- Will these set screws fit my ARRMA RC vehicle? — The M4x8mm specification is a standard fastener size used across many ARRMA models. However, specific applications may vary between different vehicle platforms. These set screws are genuine ARRMA components, so they're designed to work with ARRMA vehicles. If you're unsure whether they're suitable for your specific model, we recommend checking your vehicle's manual or contacting our RC experts at RC Model Shop for guidance.
- How many times can I reuse these set screws? — Set screws can typically be reused multiple times if removed carefully and inspected for damage. However, if threads become damaged or stripped, or if the screw becomes bent, it should be replaced. Having a pack of 10 ensures you have spares available for replacement when needed, whether due to wear, damage, or simply needing extras for additional projects.
- Are these set screws suitable for beginners? — Yes, absolutely. These are standard maintenance and assembly components suitable for RC enthusiasts of all skill levels. Beginners will find them essential for basic maintenance and repairs, whilst experienced builders will appreciate having genuine OEM fasteners for custom builds and upgrades. Understanding how to properly install and torque set screws is a fundamental skill in RC car maintenance.
- What tools do I need to install these set screws? — Set screws typically require an appropriately sized hex key or Allen wrench for installation and removal. The specific tool size depends on the socket head design of the set screw. Most ARRMA set screws use standard hex socket heads, and having a quality set of metric hex keys will cover most RC fastening tasks. Always ensure you're using the correct tool size to avoid stripping the socket.
